Type.IsEnum Property

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

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

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
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.
