Type.IsEnum Property

Gets a value indicating whether the current Type represents an enumeration.

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

Public ReadOnly Property IsEnum As Boolean
Dim instance As Type
Dim value As Boolean

value = instance.IsEnum

/** @property */
public final boolean get_IsEnum ()

public final function get IsEnum () : boolean

Property Value

true if the current Type represents an enumeration; otherwise, false.

This property returns true for an enumeration, but not for the Enum type itself.

If the current Type represents a constructed generic type, this property applies to the generic type definition from which the type was constructed. For example, if the current Type represents MyGenericType<int> (MyGenericType(Of Integer) in Visual Basic), the value of this property is determined by MyGenericType<T>.

If the current Type represents a type parameter in the definition of a generic type or generic method, this property always returns false.

This property is read-only.

The following example demonstrates how to use the IsEnum property.

Imports System

Public Enum Color
End Enum 'Color
Class TestIsEnum
   Public Shared Sub Main()
        Dim colorType As Type = GetType(Color)
        Dim enumType As Type = GetType([Enum])
        Console.WriteLine("Is Color an enum? {0}.", colorType.IsEnum)
        Console.WriteLine("Is Color a value type? {0}.", colorType.IsValueType)
        Console.WriteLine("Is Enum an enum type? {0}.", enumType.IsEnum)
        Console.WriteLine("Is Enum a value type? {0}.", enumType.IsValueType)
    End Sub 'Main
End Class 'TestType

import System.*;

enum Color
    red, blue, green;
} //Color

class TestIsEnum
    public static void main(String[] args)
        Type colorType = Color.class.ToType();
        Type enumType = Enum.class.ToType();
        Console.WriteLine("Is Color an enum? {0}.", 
        Console.WriteLine("Is Color a value type? {0}.",
        Console.WriteLine("Is Enum an enum Type? {0}.",
        Console.WriteLine("Is Enum a value type? {0}.", 
    } //main
} //TestIsEnum

This code produces the following output:

Is Color an enum? True.
Is Color a value type? True.
Is Enum an enum type? False.
Is Enum a value type? False.
