IDispatchMessageInspector.BeforeSendReply(Message, Object) 메서드

정의

네임스페이스:

System.ServiceModel.Dispatcher

어셈블리:

System.ServiceModel.Primitives.dll

어셈블리:

System.ServiceModel.dll

작업이 반환된 후 회신 메시지를 보내기 전에 호출됩니다.

public:
 void BeforeSendReply(System::ServiceModel::Channels::Message ^ % reply, System::Object ^ correlationState);

public void BeforeSendReply (ref System.ServiceModel.Channels.Message reply, object correlationState);

abstract member BeforeSendReply : Message * obj -> unit

Public Sub BeforeSendReply (ByRef reply As Message, correlationState As Object)

매개 변수

reply

Message

회신 메시지입니다. 작업이 단방향일 경우 이 값은 null입니다.

correlationState

Object

AfterReceiveRequest(Message, IClientChannel, InstanceContext) 메서드에서 반환된 상관 관계 개체입니다.

예제

다음 코드 예제에서는 콘솔이 호출될 때 해당 콘솔에 문자열을 쓰는 기본 IDispatchMessageInspector를 보여 줍니다.

public object AfterReceiveRequest(ref System.ServiceModel.Channels.Message request, IClientChannel channel, InstanceContext instanceContext)
{
  Console.WriteLine("IDispatchMessageInspector.AfterReceiveRequest called.");
  return null;

설명

반환 메시지를 보내기 전에 사용자 지정 동작을 수행하려면 BeforeSendReply 메서드를 사용합니다. correlationState는 인바운드 호출과 아웃바운드 호출 간에 상호 연결을 수행하여 사용자 동작을 지원하는 데 사용할 수 있는 AfterReceiveRequest 메서드에서 반환된 개체입니다.
