Public Overridable ReadOnly Property IsEnum As Boolean

Public ReadOnly Property IsEnum As Boolean

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

The following example demonstrates how to use the IsEnum property.

using namespace System;
enum class Color
{ Red, Blue, Green };

int main()
{
   Type^ colorType = Color::typeid;
   Type^ enumType = Enum::typeid;
   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.

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.

open System
type Color =
    | Red = 0
    | Blue = 1
    | Green = 2

let colorType = typeof<Color>
let enumType = typeof<Enum>
printfn $"Is Color an enum? {colorType.IsEnum}."
printfn $"Is Color a value type? {colorType.IsValueType}."
printfn $"Is Enum an enum Type? {enumType.IsEnum}."
printfn $"Is Enum a value type? {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.

Public Enum Color

Class Example
   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 
End Class
' 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.

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.
