IDispatchMessageInspector.AfterReceiveRequest メソッド

public:
 System::Object ^ AfterReceiveRequest(System::ServiceModel::Channels::Message ^ % request, System::ServiceModel::IClientChannel ^ channel, System::ServiceModel::InstanceContext ^ instanceContext);

public object AfterReceiveRequest (ref System.ServiceModel.Channels.Message request, System.ServiceModel.IClientChannel channel, System.ServiceModel.InstanceContext instanceContext);

abstract member AfterReceiveRequest : Message * System.ServiceModel.IClientChannel * System.ServiceModel.InstanceContext -> obj

Public Function AfterReceiveRequest (ByRef request As Message, channel As IClientChannel, instanceContext As InstanceContext) As Object

パラメーター

戻り値

状態を関連付けるために使用されるオブジェクト。 このオブジェクトは、BeforeSendReply(Message, Object) メソッドで返されます。

例

次のコード例は、呼び出されたときにコンソールに文字列を書き込む基本的な IDispatchMessageInspector を示しています。

#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

次のコード例は、DispatchRuntime.MessageInspectors コレクションに InspectorIDispatchMessageInspector を追加する IServiceBehavior の実装を示しています。

#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

注釈

AfterReceiveRequest メソッドを使用して、受信メッセージ、それを提供したクライアント チャネル、および現在のサービス インスタンスを検査または変更します。 戻り値には、関連付けのために使用する任意のオブジェクトを指定できます。BeforeSendReply メソッドの correlationState パラメーターとして返されます。
