Type.IsEnum Property

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

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

public bool IsEnum { get; }
/** @property */
public final boolean get_IsEnum ()

public final function get IsEnum () : boolean

Not applicable.

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.

using System;
public enum Color 
{
Red, Blue, Green
}
class TestIsEnum 
{
    public static void Main() 
    {
       Type colorType = typeof(Color);
       Type enumType = typeof(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);
   }
}

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}.", 
            System.Convert.ToString(colorType.get_IsEnum()));
        Console.WriteLine("Is Color a value type? {0}.",
            System.Convert.ToString(colorType.get_IsValueType()));
        Console.WriteLine("Is Enum an enum Type? {0}.",
            System.Convert.ToString(enumType.get_IsEnum()));
        Console.WriteLine("Is Enum a value type? {0}.", 
            System.Convert.ToString(enumType.get_IsValueType()));
    } //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.
