TypeBuilder.AddInterfaceImplementation(Type) Method

Definition

Namespace:

System.Reflection.Emit

Assembly:

System.Reflection.Emit.dll

Source:

TypeBuilder.cs

Adds an interface that this type implements.

public:
 void AddInterfaceImplementation(Type ^ interfaceType);

public void AddInterfaceImplementation (Type interfaceType);

member this.AddInterfaceImplementation : Type -> unit

Public Sub AddInterfaceImplementation (interfaceType As Type)

Parameters

interfaceType

Type

The interface that this type implements.

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)
