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

<ComVisibleAttribute(True)> _
Public Shared Function GetName ( _
	enumType As Type, _
	value As Object _
) As String


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

Return Value

Type: System.String
A string containing the name of the enumerated constant in enumType whose value is value; or Nothing if no such constant is found.


enumType or value is Nothing.


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.

Imports System

Public Class GetNameTest

    Enum Colors
    End Enum 'Colors

    Enum Styles
    End Enum 'Styles

    Public Shared Sub Main() 
        Console.WriteLine("The 4th value of the Colors Enum is {0}", [Enum].GetName(GetType(Colors), 3))
        Console.WriteLine("The 4th value of the Styles Enum is {0}", [Enum].GetName(GetType(Styles), 3))
    End Sub 'Main
End Class 'GetNameTest
' The example displays the following output:
'       The 4th value of the Colors Enum is Yellow
'       The 4th value of the Styles Enum is Corduroy
