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 */
public final boolean get_IsInterface ()

public final function get IsInterface () : boolean

Property Value

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 MyIsInterface 
{
    public static void Main(string []args)
    {
        try
        {
            // Get the IsInterface attribute for myIFace.
            bool myBool1 = typeof(myIFace).IsInterface;    
            //Display the IsInterface attribute for myIFace.
            Console.WriteLine("Is the specified type an interface? {0}.", myBool1);
            // Get the attribute IsInterface for MyIsInterface.
            bool myBool2 = typeof(MyIsInterface).IsInterface;    
            //Display the IsInterface attribute for MyIsInterface.
            Console.WriteLine("Is the specified type an interface? {0}.", myBool2);         
        }
        catch(Exception e)
        {
            Console.WriteLine("\nAn exception occurred: {0}.", e.Message);
        }
    }
}

import System.*;

// Declare an interface.
interface myIFace
{
} //myIFace

class MyIsInterface
{
    public static void main(String[] args)
    {
        try {
            // Get the IsInterface attribute for myIFace.
            boolean myBool1 = myIFace.class.ToType().get_IsInterface();

            //Display the IsInterface attribute for myIFace.
            Console.WriteLine("Is the specified type an interface? {0}.",
                System.Convert.ToString(myBool1));

            // Get the attribute IsInterface for MyIsInterface.
            boolean myBool2 = MyIsInterface.class.ToType().get_IsInterface();

            //Display the IsInterface attribute for MyIsInterface.
            Console.WriteLine("Is the specified type an interface? {0}.",
                System.Convert.ToString(myBool2));
        }
        catch (System.Exception e) {
            Console.WriteLine("\nAn exception occurred: {0}.",
                e.get_Message());
        }
    } //main
} //MyIsInterface
