public void AddInterfaceImplementation (Type interfaceType);

[System.Runtime.InteropServices.ComVisible(true)]
public void AddInterfaceImplementation (Type interfaceType);

member this.AddInterfaceImplementation : Type -> unit

[<System.Runtime.InteropServices.ComVisible(true)>]
member this.AddInterfaceImplementation : Type -> unit

Public Sub AddInterfaceImplementation (interfaceType As Type)

Parameters

interfaceType: Type

The interface that this type implements.

Attributes: ComVisibleAttribute

Exceptions

ArgumentNullException

interfaceType is null.

InvalidOperationException

The type was previously created using CreateType().

Examples

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,
      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 );

 // 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);

' Mark the class as implementing 'IHello' interface.
helloWorldTypeBuilder.AddInterfaceImplementation(GetType(IHello))
Dim myMethodBuilder As MethodBuilder = helloWorldTypeBuilder.DefineMethod("SayHello", _
                     MethodAttributes.Public Or MethodAttributes.Virtual, Nothing, Nothing)
' Generate IL for 'SayHello' method.
Dim myMethodIL As ILGenerator = myMethodBuilder.GetILGenerator()
myMethodIL.EmitWriteLine(myGreetingField)
myMethodIL.Emit(OpCodes.Ret)
Dim sayHelloMethod As MethodInfo = GetType(IHello).GetMethod("SayHello")
helloWorldTypeBuilder.DefineMethodOverride(myMethodBuilder, sayHelloMethod)
