How to get the current user in ASP.NET MVC
C#.Netasp.net MvcIisForms AuthenticationC# Problem Overview
In a forms model, I used to get the current logged-in user by:
Page.CurrentUser
How do I get the current user inside a controller class in ASP.NET MVC?
C# Solutions
Solution 1 - C#
If you need to get the user from within the controller, use the User
property of Controller. If you need it from the view, I would populate what you specifically need in the ViewData
, or you could just call User as I think it's a property of ViewPage
.
Solution 2 - C#
I found that User
works, that is, User.Identity.Name
or User.IsInRole("Administrator")
.
Solution 3 - C#
Try HttpContext.Current.User
.
> Public Shared Property Current() As
> System.Web.HttpContext
> Member of System.Web.HttpContext
>
> Summary:
> Gets or sets the System.Web.HttpContext object for the current HTTP request.
>
> Return Values:
> The System.Web.HttpContext for the current
> HTTP request

You can get the name of the user in ASP.NET MVC4 like this:
System.Web.HttpContext.Current.User.Identity.Name
Solution 5 - C#
I realize this is really old, but I'm just getting started with ASP.NET MVC, so I thought I'd stick my two cents in:
Request.IsAuthenticated
tells you if the user is authenticated.Page.User.Identity
gives you the identity of the logged-in user.
Solution 6 - C#
I use:
Membership.GetUser().UserName
I am not sure this will work in ASP.NET MVC, but it's worth a shot :)
Solution 7 - C#
getting logged in username: System.Web.HttpContext.Current.User.Identity.Name
Solution 8 - C#
UserName with:
User.Identity.Name
But if you need to get just the ID, you can use:
using Microsoft.AspNet.Identity;
So, you can get directly the User ID:
User.Identity.GetUserId();
Solution 9 - C#
In order to reference a user ID created using simple authentication built into ASP.NET MVC 4 in a controller for filtering purposes (which is helpful if you are using database first and Entity Framework 5 to generate code-first bindings and your tables are structured so that a foreign key to the userID is used), you can use
WebSecurity.CurrentUserId
once you add a using statement
using System.Web.Security;

We can use following code to get the current logged in User in ASP.Net MVC:
var user= System.Web.HttpContext.Current.User.Identity.GetUserName();
Also
var userName = System.Security.Principal.WindowsIdentity.GetCurrent().Name; //will give 'Domain//UserName'
Environment.UserName - Will Display format : 'Username'

You just need User.Identity.Name
.
Solution 12 - C#
Use System.Security.Principal.WindowsIdentity.GetCurrent().Name
.
This will get the current logged-in Windows user.
Solution 13 - C#
For what it's worth, in ASP.NET MVC 3 you can just use User which returns the user for the current request.
Solution 14 - C#
If you are inside your login page, in LoginUser_LoggedIn event for instance, Current.User.Identity.Name will return an empty value, so you have to use yourLoginControlName.UserName property.
MembershipUser u = Membership.GetUser(LoginUser.UserName);
Solution 15 - C#
You can use following code:
Request.LogonUserIdentity.Name;
Solution 16 - C#
IPrincipal currentUser = HttpContext.Current.User;
bool writeEnable = currentUser.IsInRole("Administrator") ||
...
currentUser.IsInRole("Operator");
Solution 17 - C#
var ticket = FormsAuthentication.Decrypt(
HttpContext.Current.Request.Cookies[FormsAuthentication.FormsCookieName].Value);
if (ticket.Expired)
{
throw new InvalidOperationException("Ticket expired.");
}
IPrincipal user = (System.Security.Principal.IPrincipal) new RolePrincipal(new FormsIdentity(ticket));

If you happen to be working in Active Directory on an intranet, here are some tips:
(Windows Server 2012)
Running anything that talks to AD on a web server requires a bunch of changes and patience. Since when running on a web server vs. local IIS/IIS Express it runs in the AppPool's identity so, you have to set it up to impersonate whoever hits the site.
How to get the current logged-in user in an active directory when your ASP.NET MVC application is running on a web server inside the network:
// Find currently logged in user
UserPrincipal adUser = null;
using (HostingEnvironment.Impersonate())
{
var userContext = System.Web.HttpContext.Current.User.Identity;
PrincipalContext ctx = new PrincipalContext(ContextType.Domain, ConfigurationManager.AppSettings["AllowedDomain"], null,
ContextOptions.Negotiate | ContextOptions.SecureSocketLayer);
adUser = UserPrincipal.FindByIdentity(ctx, userContext.Name);
}
//Then work with 'adUser' from here...
You must wrap any calls having to do with 'active directory context' in the following so it's acting as the hosting environment to get the AD information:
using (HostingEnvironment.Impersonate()){ ... }
You must also have impersonate
set to true in your web.config:
<system.web>
<identity impersonate="true" />
You must have Windows authentication on in web.config:
<authentication mode="Windows" />

In Asp.net Mvc Identity 2,You can get the current user name by:
var username = System.Web.HttpContext.Current.User.Identity.Name;
Solution 20 - C#
In the IIS Manager, under Authentication, disable:
- Anonymous Authentication
- Forms Authentication
Then add the following to your controller, to handle testing versus server deployment:
string sUserName = null;
string url = Request.Url.ToString();
if (url.Contains("localhost"))
sUserName = System.Security.Principal.WindowsIdentity.GetCurrent().Name;
else
sUserName = User.Identity.Name;
