Type.IsEnum Property
Gets a value indicating whether the current Type represents an enumeration.
[Visual Basic] Public ReadOnly Property IsEnum As Boolean [C#] public bool IsEnum {get;} [C++] public: __property bool get_IsEnum(); [JScript] public function get IsEnum() : Boolean;
Property Value
true if the current Type represents an enumeration; otherwise, false.
Remarks
This property returns true for an enumeration, but not for the Enum type itself, which is a class.
This property is read-only.
Example
[Visual Basic, C#, C++] The following example demonstrates using the IsEnum property.
[Visual Basic] Imports System Public Enum Color Red Blue Green 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 [C#] 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); } } [C++] #using <mscorlib.dll> using namespace System; __value enum Color { Red, Blue, Green }; int main() { Type* colorType = __typeof(Color); Type* enumType = __typeof(Enum); Console::WriteLine(S"Is Color an enum? {0}.", __box(colorType->IsEnum)); Console::WriteLine(S"Is Color a value type? {0}.", __box(colorType->IsValueType)); Console::WriteLine(S"Is Enum an enum Type? {0}.", __box(enumType->IsEnum)); Console::WriteLine(S"Is Enum a value type? {0}.", __box(enumType->IsValueType)); }
[Visual Basic, C#, C++] This code produces the following output:
Color is enum? True
Color is valueType? True
Enum is enum Type? False
Enum is value? False
