How can I retrieve the namespace to a string C#

C#StringNamespaces

C# Problem Overview


I am writing a program which needs the namespace of the program but I cant seem to figure out how to retrieve it. I would like the end result to be in a string.

I was able to find an MSDN page about this topic but it proved to be unhelpful to myself. http://msdn.microsoft.com/en-us/library/system.type.namespace.aspx

Any help would be appreciated. The program is written in C#.

EDIT: Sorry guys, this is not a console application.

C# Solutions


Solution 1 - C#

This should work:

var myType = typeof(MyClass);
var n = myType.Namespace;

Write out to the console:

Type myType = typeof(MyClass);
Console.WriteLine("Namespace: {0}.", myType.Namespace);

Setting a WinForm label:

Type myType = typeof(MyClass);
namespaceLabel.Text = myType.Namespace;

Or create a method in the relevant class and use anywhere:

public string GetThisNamespace()
{
   return GetType().Namespace;
}

Solution 2 - C#

To add to all the answers.

Since C# 6.0 there is the nameof keyword.

string name = nameof(MyNamespace);

This has several advantages:

  1. The name is resolved at compile-time
  2. The name will change when refactoring the namespace
  3. It is syntax checked, so the name must exist
  4. cleaner code

Note: This doesn't give the full namespace though. In this case, name will be equal to Bar:

namespace Foo.Bar
{
   string name = nameof(Foo.Bar);
}

Solution 3 - C#

Put this to your assembly:

public static string GetCurrentNamespace()
{
	return System.Reflection.Assembly.GetExecutingAssembly().EntryPoint.DeclaringType.Namespace;
}

Or if you want this method to be in a library used by your program, write it like this:

[System.Runtime.CompilerServices.MethodImpl(MethodImplOptions.NoInlining)]
public static string GetCurrentNamespace()
{
	return System.Reflection.Assembly.GetCallingAssembly().EntryPoint.DeclaringType.Namespace;
}

Solution 4 - C#

This can't go wrong:

MethodBase.GetCurrentMethod().DeclaringType.Namespace

Solution 5 - C#

if you have item x of class A in namespace B you can use:

string s = x.GetType().Namespace;

no s contains "B"

you can also use x.GetType().Name to get the type name or x.GetType().FullName to get both

Solution 6 - C#

You could simply use typeof and then pass in the class (I.e. Program):

Console.WriteLine(typeof(Program).Namespace); 

Which would print:

ConsoleApplication1

Solution 7 - C#

Type myType = typeof(MyClass);
// Get the namespace of the myClass class.
Console.WriteLine("Namespace: {0}.", myType.Namespace);

Building on Joe's comment you can still use

Type myType = typeof(MyClass);
// Get the namespace of the myClass class.
var namespaceName = myType.Namespace.ToString();

with namespaceName being a variable to access the namespace name as a string value.

Solution 8 - C#

If you're executing it from a class in the namespace you need to capture then you can just use:

GetType().Namespace

This works nicely as it then allows you to refactor the namespace and will still work.

Solution 9 - C#

as a roll upp all post answers: getting all columns' values from a table given as a string tableName:

 var tableName = "INVENTORY_PRICE";
            var assembly = Assembly.GetExecutingAssembly();

            var tip = typeof(Form3);

            var t = assembly.GetType(tip.Namespace + "." + tableName);
            if (t != null)
            {
                var foos = db.GetTable(t);

                foreach (var f in foos)
                {
                    Console.WriteLine(f + ":");
                    foreach (var property in f.GetType().GetProperties())
                        if (property != null)
                        {
                            var pv = property.GetValue(f, null);
                            Console.WriteLine("   " + property.Name + ":" + pv);
                        }

                    Console.WriteLine("------------------------------------------------");
                }
            }

it is very easy if we use ado, this sample uses LINQ context...
