The following code sample demonstrates the implementation of an interface on a dynamically created type using AddInterfaceImplementation.

 // Mark the class as implementing 'IHello' interface.
 helloWorldTypeBuilder.AddInterfaceImplementation(typeof(IHello));
 MethodBuilder myMethodBuilder =
    helloWorldTypeBuilder.DefineMethod("SayHello",
                         MethodAttributes.Public|MethodAttributes.Virtual,
                         null,
                         null);
 // Generate IL for 'SayHello' method.
 ILGenerator myMethodIL = myMethodBuilder.GetILGenerator();
 myMethodIL.EmitWriteLine(myGreetingField);
 myMethodIL.Emit(OpCodes.Ret);
MethodInfo sayHelloMethod = typeof(IHello).GetMethod("SayHello");
helloWorldTypeBuilder.DefineMethodOverride(myMethodBuilder,sayHelloMethod);
