Type.IsEnum Property

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

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

'Declaration
Public ReadOnly Property IsEnum As Boolean

Property Value

Type: System.Boolean
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.



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


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.
