Enum.GetName Method

Updated: August 2009

Retrieves the name of the constant in the specified enumeration that has the specified value.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

public static string GetName(
	Type enumType,
	Object value


Type: System.Type
An enumeration type.
Type: System.Object
The value of the underlying type of a particular enumerated constant.

Return Value

Type: System.String
A string containing the name of the enumerated constant in enumType whose value is value, or a null if no such constant is found.


enumType or value is a null.


enumType is not an Enum.


value is neither of type enumType nor does it have the same underlying type as enumType.

If multiple enumeration members have the same underlying value, the GetName method guarantees that it will return the name of one of those enumeration members. However, it does not guarantee that it will always return the name of the same enumeration member. As a result, when multiple enumeration members have the same value, your application code should never depend on the method returning a particular member's name.

The following example illustrates the use of GetName.

using System;

public class Example
   enum Colors { Red, Green, Blue, Yellow };
   enum Styles { Plaid, Striped, Tartan, Corduroy };

   public static void Demo(System.Windows.Controls.TextBlock outputBlock)

      outputBlock.Text += String.Format("The 4th value of the Colors Enum is {0}", Enum.GetName(typeof(Colors), 3)) + "\n";
      outputBlock.Text += String.Format("The 4th value of the Styles Enum is {0}", Enum.GetName(typeof(Styles), 3)) + "\n";
// The example displays the following output:
//       The 4th value of the Colors Enum is Yellow
//       The 4th value of the Styles Enum is Corduroy
