IDispatchMessageInspector.BeforeSendReply(Message, Object) 메서드

정의

네임스페이스:

System.ServiceModel.Primitives.dll

패키지:

System.ServiceModel.Primitives v8.0.0

Source:

IDispatchMessageInspector.cs

작업이 반환된 후 회신 메시지가 전송되기 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 한 가지 방법인 경우 이 값은 null입니다.

correlationState

Object

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

예제

다음 코드 예제에서는 호출될 때 콘솔에 문자열을 쓰는 기본 IDispatchMessageInspector 보여 줍니다.

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

public void BeforeSendReply(ref System.ServiceModel.Channels.Message reply, object correlationState)
{
  Console.WriteLine("IDispatchMessageInspector.BeforeSendReply called.");
}
#endregion

#Region "IDispatchMessageInspector Members"
    Public Function AfterReceiveRequest(ByRef request As System.ServiceModel.Channels.Message, _
                       ByVal channel As IClientChannel, ByVal instanceContext As InstanceContext) _
                       As Object Implements IDispatchMessageInspector.AfterReceiveRequest
        Console.WriteLine("IDispatchMessageInspector.AfterReceiveRequest called.")
        Return Nothing
    End Function

    Public Sub BeforeSendReply(ByRef reply As System.ServiceModel.Channels.Message, ByVal correlationState As Object) _
    Implements IDispatchMessageInspector.BeforeSendReply
        Console.WriteLine("IDispatchMessageInspector.BeforeSendReply called.")
    End Sub
#End Region

다음 코드 예제에서는 DispatchRuntime.MessageInspectors 컬렉션에 InspectorIDispatchMessageInspector 추가 하는 IServiceBehavior 구현 합니다.

#region IServiceBehavior Members
public void AddBindingParameters(
  ServiceDescription serviceDescription,
  ServiceHostBase serviceHostBase,
  System.Collections.ObjectModel.Collection<ServiceEndpoint> endpoints,
  BindingParameterCollection bindingParameters
)
{ return; }

public void ApplyDispatchBehavior(ServiceDescription serviceDescription, ServiceHostBase serviceHostBase)
{
  foreach (ChannelDispatcher chDisp in serviceHostBase.ChannelDispatchers)
  {
    foreach (EndpointDispatcher epDisp in chDisp.Endpoints)
    {
      epDisp.DispatchRuntime.MessageInspectors.Add(new Inspector());
      foreach (DispatchOperation op in epDisp.DispatchRuntime.Operations)
        op.ParameterInspectors.Add(new Inspector());
    }
  }
}

#Region "IServiceBehavior Members"
    Public Sub AddBindingParameters(ByVal serviceDescription As ServiceDescription, _
                   ByVal serviceHostBase As ServiceHostBase, ByVal endpoints As  _
                   System.Collections.ObjectModel.Collection(Of ServiceEndpoint), _
                   ByVal bindingParameters As BindingParameterCollection) Implements IServiceBehavior.AddBindingParameters
        Return
    End Sub

    Public Sub ApplyDispatchBehavior(ByVal serviceDescription As ServiceDescription, _
                                     ByVal serviceHostBase As ServiceHostBase) Implements _
                                     IServiceBehavior.ApplyDispatchBehavior
        For Each chDisp As ChannelDispatcher In serviceHostBase.ChannelDispatchers
            For Each epDisp As EndpointDispatcher In chDisp.Endpoints
                epDisp.DispatchRuntime.MessageInspectors.Add(New Inspector())
                For Each op As DispatchOperation In epDisp.DispatchRuntime.Operations
                    op.ParameterInspectors.Add(New Inspector())
                Next op
            Next epDisp
        Next chDisp
    End Sub

다음 코드 예제에서는 애플리케이션 구성 파일을 사용하여 InspectorIDispatchMessageInspector삽입하는 서비스 동작을 로드하는 방법을 보여 줍니다.

설명

BeforeSendReply 메서드를 사용하여 반환 메시지를 보내기 전에 사용자 지정 동작을 수행합니다. correlationState 동작을 지원하기 위해 인바운드 호출과 아웃바운드 호출 간의 상관 관계를 수행하는 데 사용할 수 있는 AfterReceiveRequest 메서드에서 반환되는 개체입니다.
