TypeBuilder::AddInterfaceImplementation Method

Adds an interface that this type implements.

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

void AddInterfaceImplementation(
	Type^ interfaceType


Type: System::Type
The interface that this type implements.


interfaceType is nullptr.


The type was previously created using CreateType.

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( IHello::typeid );
MethodBuilder^ myMethodBuilder =
   helloWorldTypeBuilder->DefineMethod( "SayHello",
      (MethodAttributes)(MethodAttributes::Public | MethodAttributes::Virtual),
      nullptr );
// Generate IL for 'SayHello' method.
ILGenerator^ myMethodIL = myMethodBuilder->GetILGenerator();
myMethodIL->EmitWriteLine( myGreetingField );
myMethodIL->Emit( OpCodes::Ret );
MethodInfo^ sayHelloMethod = IHello::typeid->GetMethod( "SayHello" );
helloWorldTypeBuilder->DefineMethodOverride( myMethodBuilder, sayHelloMethod );
