How to get the Display Name Attribute of an Enum member via MVC Razor code?

I've got a property in my model called Promotion that its type is a flag enum called UserPromotion. Members of my enum have display attributes set as follows:

[Flags]
public enum UserPromotion
{
    None = 0x0,

    [Display(Name = "Send Job Offers By Mail")]
    SendJobOffersByMail = 0x1,

    [Display(Name = "Send Job Offers By Sms")]
    SendJobOffersBySms = 0x2,

    [Display(Name = "Send Other Stuff By Sms")]
    SendPromotionalBySms = 0x4,

    [Display(Name = "Send Other Stuff By Mail")]
    SendPromotionalByMail = 0x8
}

Now I want to be able to create say a ul in my view to show the selected values of my Promotion property. This is what I have done so far but the problem is that how can I get the display names here?

<ul>
    @foreach (int aPromotion in @Enum.GetValues(typeof(UserPromotion)))
    {
        var currentPromotion = (int)Model.JobSeeker.Promotion;
        if ((currentPromotion & aPromotion) == aPromotion)
        {
        <li>Here I don't know how to get the display attribute of "currentPromotion".</li>
        }
    }
</ul>

One liner - Fluent syntax

public static class Extensions
{
    /// <summary>
    ///     A generic extension method that aids in reflecting 
    ///     and retrieving any attribute that is applied to an `Enum`.
    /// </summary>
	public static TAttribute GetAttribute<TAttribute>(this Enum enumValue) 
            where TAttribute : Attribute
	{
		return enumValue.GetType()
						.GetMember(enumValue.ToString())
					   	.First()
					   	.GetCustomAttribute<TAttribute>();
	}
}

---

Example

public enum Season 
{
   [Display(Name = "It's autumn")]
   Autumn,

   [Display(Name = "It's winter")]
   Winter,

   [Display(Name = "It's spring")]
   Spring,

   [Display(Name = "It's summer")]
   Summer
}

public class Foo 
{
	public Season Season = Season.Summer;
	
	public void DisplayName()
	{
		var seasonDisplayName = Season.GetAttribute<DisplayAttribute>();
		Console.WriteLine("Which season is it?");
		Console.WriteLine (seasonDisplayName.Name);
	} 
}

---

Output

> Which season is it?
> It's summer

UPDATE

First solution was focused on getting display names from enum. Code below should be exact solution for your problem.

You can use this helper class for enums:

using System;
using System.Collections.Generic;
using System.ComponentModel.DataAnnotations;
using System.Linq;
using System.Reflection;

public static class EnumHelper<T>
    where T : struct, Enum // This constraint requires C# 7.3 or later.
{
    public static IList<T> GetValues(Enum value)
    {
        var enumValues = new List<T>();

        foreach (FieldInfo fi in value.GetType().GetFields(BindingFlags.Static | BindingFlags.Public))
        {
            enumValues.Add((T)Enum.Parse(value.GetType(), fi.Name, false));
        }
        return enumValues;
    }

    public static T Parse(string value)
    {
        return (T)Enum.Parse(typeof(T), value, true);
    }

    public static IList<string> GetNames(Enum value)
    {
        return value.GetType().GetFields(BindingFlags.Static | BindingFlags.Public).Select(fi => fi.Name).ToList();
    }

    public static IList<string> GetDisplayValues(Enum value)
    {
        return GetNames(value).Select(obj => GetDisplayValue(Parse(obj))).ToList();
    }

    private static string lookupResource(Type resourceManagerProvider, string resourceKey)
    {
        var resourceKeyProperty = resourceManagerProvider.GetProperty(resourceKey,
            BindingFlags.Static | BindingFlags.Public, null, typeof(string),
            new Type[0], null);
        if (resourceKeyProperty != null)
        {
            return (string)resourceKeyProperty.GetMethod.Invoke(null, null);
        }

        return resourceKey; // Fallback with the key name
    }

    public static string GetDisplayValue(T value)
    {
        var fieldInfo = value.GetType().GetField(value.ToString());

        var descriptionAttributes = fieldInfo.GetCustomAttributes(
            typeof(DisplayAttribute), false) as DisplayAttribute[];

        if (descriptionAttributes[0].ResourceType != null)
            return lookupResource(descriptionAttributes[0].ResourceType, descriptionAttributes[0].Name);

        if (descriptionAttributes == null) return string.Empty;
        return (descriptionAttributes.Length > 0) ? descriptionAttributes[0].Name : value.ToString();
    }
}

And then you can use it in your view as following:

<ul>
    @foreach (var value in @EnumHelper<UserPromotion>.GetValues(UserPromotion.None))
    {
         if (value == Model.JobSeeker.Promotion)
        {
            var description = EnumHelper<UserPromotion>.GetDisplayValue(value);
            <li>@Html.DisplayFor(e => description )</li>
        }
    }
</ul>

Hope it helps! :)

Building on Aydin's great answer, here's an extension method that doesn't require any type parameters.

using System;
using System.ComponentModel.DataAnnotations;
using System.Linq;
using System.Reflection;

public static class EnumExtensions
{
    public static string GetDisplayName(this Enum enumValue)
    {
        return enumValue.GetType()
                        .GetMember(enumValue.ToString())
                        .First()
                        .GetCustomAttribute<DisplayAttribute>()
                        .GetName();
    }
}

NOTE: GetName() should be used instead of the Name property. This ensures that the localized string will be returned if using the ResourceType attribute property.

Example

To use it, just reference the enum value in your view.

@{
    UserPromotion promo = UserPromotion.SendJobOffersByMail;
}

Promotion: @promo.GetDisplayName()

Output

Promotion: Send Job Offers By Mail

Based on Aydin's answer I would suggest a less "duplicatious" implementation (because we could easily get the Type from the Enum value itself, instead of providing it as a parameter :

using System;
using System.ComponentModel.DataAnnotations;
using System.Linq;
using System.Reflection;

public static string GetDisplayName(this Enum enumValue)
{
    return enumValue.GetType().GetMember(enumValue.ToString())
                   .First()
                   .GetCustomAttribute<DisplayAttribute>()
                   .Name;
}

EDIT (based upon @Vahagn Nahapetyan's comment)

public static string GetDisplayName(this Enum enumValue)
{
    return enumValue.GetType()?
                    .GetMember(enumValue.ToString())?
                    .First()?
                    .GetCustomAttribute<DisplayAttribute>()?
                    .Name;
}

Now we can use it very clean in this way:

public enum Season 
{
    [Display(Name = "The Autumn")]
    Autumn,

    [Display(Name = "The Weather")]
    Winter,

    [Display(Name = "The Tease")]
    Spring,

    [Display(Name = "The Dream")]
    Summer
}

Season.Summer.GetDisplayName();

Which results in

> "The Dream"

If you are using MVC 5.1 or upper there is simplier and clearer way: just use data annotation (from System.ComponentModel.DataAnnotations namespace) like below:

public enum Color
{
    [Display(Name = "Dark red")]
    DarkRed,
    [Display(Name = "Very dark red")]
    VeryDarkRed,
    [Display(Name = "Red or just black?")]
    ReallyDarkRed
}

And in view, just put it into proper html helper:

@Html.EnumDropDownListFor(model => model.Color)

Building on Todd's great answer which built on Aydin's great answer, here's a generic extension method which doesn't require any type parameters.

/// <summary>
/// Gets human-readable version of enum.
/// </summary>
/// <returns>effective DisplayAttribute.Name of given enum.</returns>
public static string GetDisplayName<T>(this T enumValue) where T : IComparable, IFormattable, IConvertible
{
    if (!typeof(T).IsEnum)
        throw new ArgumentException("Argument must be of type Enum");

	DisplayAttribute displayAttribute = enumValue.GetType()
												 .GetMember(enumValue.ToString())
												 .First()
												 .GetCustomAttribute<DisplayAttribute>();

	string displayName = displayAttribute?.GetName();

	return displayName ?? enumValue.ToString();
}

I needed this for my project because something like the below code, where not every member of the enum has a DisplayAttribute, throws an exception with Todd's solution:

public class MyClass
{
    public enum MyEnum 
    {
    	[Display(Name="ONE")]
		One,
		// No DisplayAttribute
		Two
	}
    public void UseMyEnum()
    {
        MyEnum foo = MyEnum.One;
        MyEnum bar = MyEnum.Two;
        Console.WriteLine(foo.GetDisplayName());
        Console.WriteLine(bar.GetDisplayName());
    }
}
// Output:
//
// ONE
// Two

If this is a complicated solution to a simple problem, please let me know, but this was the fix I used.

You could use Type.GetMember Method, then get the attribute info using reflection:

// display attribute of "currentPromotion"

var type = typeof(UserPromotion);
var memberInfo = type.GetMember(currentPromotion.ToString());
var attributes = memberInfo[0].GetCustomAttributes(typeof(DisplayAttribute), false);
var description = ((DisplayAttribute)attributes[0]).Name;

There were a few similar posts here:

https://stackoverflow.com/questions/1799370/getting-attributes-of-enums-value

https://stackoverflow.com/questions/6245074/how-to-make-mvc3-displayfor-show-the-value-of-an-enums-display-attribute

For ASP.Net Core 3.0, this worked for me (credit to previous answerers).

My Enum class:

using System;
using System.Linq;
using System.ComponentModel.DataAnnotations;
using System.Reflection;

public class Enums
{
    public enum Duration
    { 
        [Display(Name = "1 Hour")]
        OneHour,
        [Display(Name = "1 Day")]
        OneDay
    }
    
    // Helper method to display the name of the enum values.
    public static string GetDisplayName(Enum value)
    {
        return value.GetType()?
       .GetMember(value.ToString())?.First()?
       .GetCustomAttribute<DisplayAttribute>()?
       .Name;
    }
}

My View Model Class:

public class MyViewModel
{
    public Duration Duration { get; set; }
}

An example of a razor view displaying a label and a drop-down list. Notice the drop-down list does not require a helper method:

@model IEnumerable<MyViewModel> 

@foreach (var item in Model)
{
    <label asp-for="@item.Duration">@Enums.GetDisplayName(item.Duration)</label>
    <div class="form-group">
        <label asp-for="@item.Duration" class="control-label">Select Duration</label>
        <select asp-for="@item.Duration" class="form-control"
            asp-items="Html.GetEnumSelectList<Enums.Duration>()">
        </select>
    </div>
}

In .NET5, I used DisplayTextFor without needing helper or extension methods:

@Html.DisplayTextFor(m => m.SomeEnumProperty)

Where SomeEnumProperty has a value of:

public enum MyEnum
{
    [Display(Name = "Not started")]
    NotStarted = 0,
    [Display(Name = "Weird display name instead of just 'Started'")]
    Started = 1,
}

With Core 2.1,

public static string GetDisplayName(Enum enumValue)
{
  return enumValue.GetType()?
 .GetMember(enumValue.ToString())?[0]?
 .GetCustomAttribute<DisplayAttribute>()?
 .Name;
}

<ul>
    @foreach (int aPromotion in @Enum.GetValues(typeof(UserPromotion)))
    {
        var currentPromotion = (int)Model.JobSeeker.Promotion;
        if ((currentPromotion & aPromotion) == aPromotion)
        {
        <li>@Html.DisplayFor(e => currentPromotion)</li>
        }
    }
</ul>

combining all edge-cases together from above:

• enum members with base object members' names (Equals, ToString)
• optional Display attribute

here is my code:

public enum Enum
{
	[Display(Name = "What a weird name!")]
	ToString,

	Equals
}

public static class EnumHelpers
{
    public static string GetDisplayName(this Enum enumValue)
    {
        var enumType = enumValue.GetType();

        return enumType
                .GetMember(enumValue.ToString())
				.Where(x => x.MemberType == MemberTypes.Field && ((FieldInfo)x).FieldType == enumType)
				.First()
				.GetCustomAttribute<DisplayAttribute>()?.Name ?? enumValue.ToString();
	}
}

void Main()
{
	Assert.Equals("What a weird name!", Enum.ToString.GetDisplayName());
    Assert.Equals("Equals", Enum.Equals.GetDisplayName());
}

You need to use a bit of reflection in order to access that attribute:

var type = typeof(UserPromotion);
var member = type.GetMember(Model.JobSeeker.Promotion.ToString());
var attributes = member[0].GetCustomAttributes(typeof(DisplayAttribute), false);
var name = ((DisplayAttribute)attributes[0]).Name;

I recommend wrapping this method in a extension method or perform this in a view model.

I'm sorry to do this, but I couldn't use any of the other answers as-is and haven't time to duke it out in the comments.

Uses C# 6 syntax.

static class EnumExtensions
{
    /// returns the localized Name, if a [Display(Name="Localised Name")] attribute is applied to the enum member
    /// returns null if there isnt an attribute
    public static string DisplayNameOrEnumName(this Enum value)
    // => value.DisplayNameOrDefault() ?? value.ToString()
    {
        // More efficient form of ^ based on http://stackoverflow.com/a/17034624/11635
        var enumType = value.GetType();
        var enumMemberName = Enum.GetName(enumType, value);
        return enumType
            .GetEnumMemberAttribute<DisplayAttribute>(enumMemberName)
            ?.GetName() // Potentially localized
            ?? enumMemberName; // Or fall back to the enum name
    }

    /// returns the localized Name, if a [Display] attribute is applied to the enum member
    /// returns null if there is no attribute
    public static string DisplayNameOrDefault(this Enum value) =>
        value.GetEnumMemberAttribute<DisplayAttribute>()?.GetName();

    static TAttribute GetEnumMemberAttribute<TAttribute>(this Enum value) where TAttribute : Attribute =>
        value.GetType().GetEnumMemberAttribute<TAttribute>(value.ToString());

    static TAttribute GetEnumMemberAttribute<TAttribute>(this Type enumType, string enumMemberName) where TAttribute : Attribute =>
        enumType.GetMember(enumMemberName).Single().GetCustomAttribute<TAttribute>();
}

Building further on Aydin's and Todd's answers, here is an extension method that also lets you get the name from a resource file

using AppResources;
using System;
using System.ComponentModel.DataAnnotations;
using System.Linq;
using System.Reflection;
using System.Resources;

public static class EnumExtensions
{
    public static string GetDisplayName(this Enum enumValue)
    {
        var enumMember= enumValue.GetType()
                        .GetMember(enumValue.ToString());

        DisplayAttribute displayAttrib = null;
        if (enumMember.Any()) {
            displayAttrib = enumMember 
                        .First()
                        .GetCustomAttribute<DisplayAttribute>();
        }

        string name = null;
        Type resource = null;

        if (displayAttrib != null)
        {
            name = displayAttrib.Name;
            resource = displayAttrib.ResourceType;
        }

        return String.IsNullOrEmpty(name) ? enumValue.ToString()
            : resource == null ?  name
            : new ResourceManager(resource).GetString(name);
    }
}

and use it like

public enum Season 
{
    [Display(ResourceType = typeof(Resource), Name = Season_Summer")]
    Summer
}

I have two solutions for this Question.

> 1. The first solution is on getting display names from enum.

public enum CourseLocationTypes
{
    [Display(Name = "On Campus")]
    OnCampus,
    [Display(Name = "Online")]
    Online,
    [Display(Name = "Both")]
    Both
}

public static string DisplayName(this Enum value)
{
    Type enumType = value.GetType();
    string enumValue = Enum.GetName(enumType, value);
    MemberInfo member = enumType.GetMember(enumValue)[0];

    object[] attrs = member.GetCustomAttributes(typeof(DisplayAttribute), false);
    string outString = ((DisplayAttribute)attrs[0]).Name;

    if (((DisplayAttribute)attrs[0]).ResourceType != null)
    {
        outString = ((DisplayAttribute)attrs[0]).GetName();
    }

    return outString;
}

<h3 class="product-title white">@Model.CourseLocationType.DisplayName()</h3>

> 2. The second Solution is on getting display name from enum name but that will be enum split in developer language it's called patch.

public static string SplitOnCapitals(this string text)
{
        var r = new Regex(@"
            (?<=[A-Z])(?=[A-Z][a-z]) |
             (?<=[^A-Z])(?=[A-Z]) |
             (?<=[A-Za-z])(?=[^A-Za-z])", RegexOptions.IgnorePatternWhitespace);

        return r.Replace(text, " ");
}

 <div class="widget-box pt-0">
     @foreach (var item in Enum.GetNames(typeof(CourseLocationType)))
     {
         <label class="pr-2 pt-1">
             @Html.RadioButtonFor(x => x.CourseLocationType, item, new { type = "radio", @class = "iCheckBox control-label" })&nbsp; @item.SplitOnCapitals()
         </label>
     }
     @Html.ValidationMessageFor(x => x.CourseLocationType)
 </div>

2020 Update: An updated version of the function provided by many in this thread but now for C# 7.3 onwards:

Now you can restrict generic methods to enums types so you can write a single method extension to use it with all your enums like this:

The generic extension method:

public static string ATexto<T>(this T enumeración) where T : struct, Enum {
    var tipo = enumeración.GetType();
    return tipo.GetMember(enumeración.ToString())
    .Where(x => x.MemberType == MemberTypes.Field && ((FieldInfo)x).FieldType == tipo).First()
    .GetCustomAttribute<DisplayAttribute>()?.Name ?? enumeración.ToString();
} 

The enum:

public enum TipoImpuesto { 
IVA, INC, [Display(Name = "IVA e INC")]IVAeINC, [Display(Name = "No aplica")]NoAplica };

How to use it:

var tipoImpuesto = TipoImpuesto.IVAeINC;
var textoTipoImpuesto = tipoImpuesto.ATexto(); // Prints "IVA e INC".

Bonus, Enums with Flags: If you are dealing with normal enums the function above is enough, but if any of your enums can take multiple values with the use of flags then you will need to modify it like this (This code uses C#8 features):

    public static string ATexto<T>(this T enumeración) where T : struct, Enum {

        var tipo = enumeración.GetType();
        var textoDirecto = enumeración.ToString();

        string obtenerTexto(string textoDirecto) => tipo.GetMember(textoDirecto)
            .Where(x => x.MemberType == MemberTypes.Field && ((FieldInfo)x).FieldType == tipo)
            .First().GetCustomAttribute<DisplayAttribute>()?.Name ?? textoDirecto;
        
        if (textoDirecto.Contains(", ")) {

            var texto = new StringBuilder();
            foreach (var textoDirectoAux in textoDirecto.Split(", ")) {
                texto.Append($"{obtenerTexto(textoDirectoAux)}, ");
            }
            return texto.ToString()[0..^2];

        } else {
            return obtenerTexto(textoDirecto);
        }

    } 

The enum with flags:

[Flags] public enum TipoContribuyente {
    [Display(Name = "Común")] Común = 1, 
    [Display(Name = "Gran Contribuyente")] GranContribuyente = 2, 
    Autorretenedor = 4, 
    [Display(Name = "Retenedor de IVA")] RetenedorIVA = 8, 
    [Display(Name = "Régimen Simple")] RégimenSimple = 16 } 

How to use it:

var tipoContribuyente = TipoContribuyente.RetenedorIVA | TipoContribuyente.GranContribuyente;
var textoAux = tipoContribuyente.ATexto(); // Prints "Gran Contribuyente, Retenedor de IVA".

I want to contribute with culture-dependent GetDisplayName enum extension. Hope this will be usefull for anyone googling this answer like me previously:

"standart" way as Aydin Adn and Todd mentioned:

    public static string GetDisplayName(this Enum enumValue)
    {
        return enumValue
            .GetType()
            .GetMember(enumValue.ToString())
            .First()
            .GetCustomAttribute<DisplayAttribute>()
            .GetName();
    }

"Culture-dependent" way:

    public static string GetDisplayName(this Enum enumValue, CultureInfo ci)
    {
        var displayAttr = enumValue
            .GetType()
            .GetMember(enumValue.ToString())
            .First()
            .GetCustomAttribute<DisplayAttribute>();

        var resMan = displayAttr.ResourceType?.GetProperty(@"ResourceManager", BindingFlags.Static | BindingFlags.Public | BindingFlags.NonPublic).GetValue(null, null) as ResourceManager;

        return resMan?.GetString(displayAttr.Name, ci) ?? displayAttr.GetName();
    }

For just displaying enum's display name attribute just use Microsoft.AspNetCore.Mvc.Rendering's

@Html.DisplayFor(x => EnumType.EnumValue)

That's would be enough.

For displaying SelectList write as following:

 <select id="someIdForTheEndPoint" asp-items="Html.GetEnumSelectList<EnumType>()">
     <option selected="selected" value="">Select value</option>
 </select>

Based on previous answers I've created this comfortable helper to support all DisplayAttribute properties in a readable way:

public static class EnumExtensions
    {
        public static DisplayAttributeValues GetDisplayAttributeValues(this Enum enumValue)
        {
            var displayAttribute = enumValue.GetType().GetMember(enumValue.ToString()).First().GetCustomAttribute<DisplayAttribute>();

            return new DisplayAttributeValues(enumValue, displayAttribute);
        }

        public sealed class DisplayAttributeValues
        {
            private readonly Enum enumValue;
            private readonly DisplayAttribute displayAttribute;

            public DisplayAttributeValues(Enum enumValue, DisplayAttribute displayAttribute)
            {
                this.enumValue = enumValue;
                this.displayAttribute = displayAttribute;
            }

            public bool? AutoGenerateField => this.displayAttribute?.GetAutoGenerateField();
            public bool? AutoGenerateFilter => this.displayAttribute?.GetAutoGenerateFilter();
            public int? Order => this.displayAttribute?.GetOrder();
            public string Description => this.displayAttribute != null ? this.displayAttribute.GetDescription() : string.Empty;
            public string GroupName => this.displayAttribute != null ? this.displayAttribute.GetGroupName() : string.Empty;
            public string Name => this.displayAttribute != null ? this.displayAttribute.GetName() : this.enumValue.ToString();
            public string Prompt => this.displayAttribute != null ? this.displayAttribute.GetPrompt() : string.Empty;
            public string ShortName => this.displayAttribute != null ? this.displayAttribute.GetShortName() : this.enumValue.ToString();
        }
    }

I tried doing this as an edit but it was rejected; I can't see why.

The above will throw an exception if you call it with an Enum that has a mix of custom attributes and plain items, e.g.

public enum CommentType
{
    All = 1,
    Rent = 2,
    Insurance = 3,
    [Display(Name="Service Charge")]
    ServiceCharge = 4
}

So I've modified the code ever so slightly to check for custom attributes before trying to access them, and use the name if none are found.

using System;
using System.Collections.Generic;
using System.ComponentModel.DataAnnotations;
using System.Linq;
using System.Reflection;

public static class EnumHelper<T>
{
    public static IList<T> GetValues(Enum value)
    {
        var enumValues = new List<T>();

        foreach (FieldInfo fi in value.GetType().GetFields(BindingFlags.Static | BindingFlags.Public))
        {
            enumValues.Add((T)Enum.Parse(value.GetType(), fi.Name, false));
        }
        return enumValues;
    }

    public static T Parse(string value)
    {
        return (T)Enum.Parse(typeof(T), value, true);
    }

    public static IList<string> GetNames(Enum value)
    {
        return value.GetType().GetFields(BindingFlags.Static | BindingFlags.Public).Select(fi => fi.Name).ToList();
    }

    public static IList<string> GetDisplayValues(Enum value)
    {
        return GetNames(value).Select(obj => GetDisplayValue(Parse(obj))).ToList();
    }

    private static string lookupResource(Type resourceManagerProvider, string resourceKey)
    {
        foreach (PropertyInfo staticProperty in resourceManagerProvider.GetProperties(BindingFlags.Static | BindingFlags.NonPublic | BindingFlags.Public))
        {
            if (staticProperty.PropertyType == typeof(System.Resources.ResourceManager))
            {
                System.Resources.ResourceManager resourceManager = (System.Resources.ResourceManager)staticProperty.GetValue(null, null);
                return resourceManager.GetString(resourceKey);
            }
        }

        return resourceKey; // Fallback with the key name
    }

    public static string GetDisplayValue(T value)
    {
        var fieldInfo = value.GetType().GetField(value.ToString());

        var descriptionAttributes = fieldInfo.GetCustomAttributes(
            typeof(DisplayAttribute), false) as DisplayAttribute[];

        if (descriptionAttributes.Any() && descriptionAttributes[0].ResourceType != null)
            return lookupResource(descriptionAttributes[0].ResourceType, descriptionAttributes[0].Name);

        if (descriptionAttributes == null) return string.Empty;
        return (descriptionAttributes.Length > 0) ? descriptionAttributes[0].Name : value.ToString();
    }
}

Using MVC5 you could use:

public enum UserPromotion
{
   None = 0x0,

   [Display(Name = "Send Job Offers By Mail")]
   SendJobOffersByMail = 0x1,

   [Display(Name = "Send Job Offers By Sms")]
   SendJobOffersBySms = 0x2,

   [Display(Name = "Send Other Stuff By Sms")]
   SendPromotionalBySms = 0x4,

   [Display(Name = "Send Other Stuff By Mail")]
   SendPromotionalByMail = 0x8
}

then if you want to create a dropdown selector you can use:

@Html.EnumDropdownListFor(expression: model => model.PromotionSelector, optionLabel: "Select") 

It is maybe cheating, but it's works:

 @foreach (var yourEnum in Html.GetEnumSelectList<YourEnum>())
 {
     @yourEnum.Text
 }
