Examples

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);
   }
}
// The example displays 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.

Remarks

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.
