Type.IsInterface Property

Gets a value indicating whether the Type is an interface; that is, not a class or a value type.

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

public bool IsInterface { get; }

Property Value

Type: System.Boolean
true if the Type is an interface; otherwise, false.

The ClassSemanticsMask distinguishes a type declaration as class, interface or value type.

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 creates an interface, checks for the interface type, and indicates whether a class has the IsInterface property set.


using System;
// Declare an interface.
interface myIFace
{
}
class Example
{
   public static void Demo(System.Windows.Controls.TextBlock outputBlock)
   {
      try
      {
         // Get the IsInterface attribute for myIFace.
         bool myBool1 = typeof(myIFace).IsInterface;
         //Display the IsInterface attribute for myIFace.
         outputBlock.Text += String.Format("Is the specified type an interface? {0}.", myBool1) + "\n";
         // Get the attribute IsInterface for Example.
         bool myBool2 = typeof(Example).IsInterface;
         //Display the IsInterface attribute for Example.
         outputBlock.Text += String.Format("Is the specified type an interface? {0}.", myBool2) + "\n";
      }
      catch (Exception e)
      {
         outputBlock.Text += String.Format("\nAn exception occurred: {0}.", e.Message) + "\n";
      }
   }
}
