Type.IsEnum Property
Microsoft Silverlight will reach end of support after October 2021. Learn more.
Gets a value indicating whether the current Type represents an enumeration.
Namespace: System
Assembly: mscorlib (in mscorlib.dll)
Syntax
'Declaration
Public ReadOnly Property IsEnum As Boolean
public bool IsEnum { get; }
Property Value
Type: System.Boolean
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.
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.
Examples
The following example demonstrates how to use the IsEnum property.

Public Enum Color
Red
Blue
Green
End Enum 'Color
Class Example
Public Shared Sub Demo(ByVal outputBlock As System.Windows.Controls.TextBlock)
Dim colorType As Type = GetType(Color)
Dim enumType As Type = GetType([Enum])
outputBlock.Text += String.Format("Is Color an enum? {0}.", colorType.IsEnum) & vbCrLf
outputBlock.Text += String.Format("Is Color a value type? {0}.", colorType.IsValueType) & vbCrLf
outputBlock.Text += String.Format("Is Enum an enum type? {0}.", enumType.IsEnum) & vbCrLf
outputBlock.Text += String.Format("Is Enum a value type? {0}.", enumType.IsValueType) & vbCrLf
End Sub 'Main
End Class 'TestType
using System;
public enum Color
{
Red, Blue, Green
}
class Example
{
public static void Demo(System.Windows.Controls.TextBlock outputBlock)
{
Type colorType = typeof(Color);
Type enumType = typeof(Enum);
outputBlock.Text += String.Format("Is Color an enum? {0}.", colorType.IsEnum) + "\n";
outputBlock.Text += String.Format("Is Color a value type? {0}.", colorType.IsValueType) + "\n";
outputBlock.Text += String.Format("Is Enum an enum Type? {0}.", enumType.IsEnum) + "\n";
outputBlock.Text += String.Format("Is Enum a value type? {0}.", enumType.IsValueType) + "\n";
}
}
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.
