public void AfterReceiveReply (ref System.ServiceModel.Channels.Message reply, object correlationState);
abstract member AfterReceiveReply :  * obj -> unit
Public Sub AfterReceiveReply (ByRef reply As Message, correlationState As Object)

Parameters

reply
Message Message Message Message

The message to be transformed into types and handed back to the client application.

correlationState
Object Object Object Object

Correlation state data.

Examples

The following code example shows an implementation that writes strings to the console when the implementation is called.

#region IClientMessageInspector Members
public void AfterReceiveReply(ref System.ServiceModel.Channels.Message reply, object correlationState)
{
  Console.WriteLine("IClientMessageInspector.AfterReceiveReply called.");
  Console.WriteLine("Message: {0}", reply.ToString());
}

public object BeforeSendRequest(ref System.ServiceModel.Channels.Message request, IClientChannel channel)
{
  Console.WriteLine("IClientMessageInspector.BeforeSendRequest called.");
  return null;
}
#Region "IClientMessageInspector Members"
       Public Sub AfterReceiveReply(ByRef reply As System.ServiceModel.Channels.Message, _
                          ByVal correlationState As Object) Implements IClientMessageInspector.AfterReceiveReply
           Console.WriteLine("IClientMessageInspector.AfterReceiveReply called.")
           Console.WriteLine("Message: {0}", reply.ToString())
       End Sub

       Public Function BeforeSendRequest(ByRef request As System.ServiceModel.Channels.Message, _
               ByVal channel As IClientChannel) As Object Implements IClientMessageInspector.BeforeSendRequest
           Console.WriteLine("IClientMessageInspector.BeforeSendRequest called.")
           Return Nothing
       End Function

The following code example shows how to use an System.ServiceModel.Description.IEndpointBehavior to insert the client message inspector in the client endpoint.

#region IEndpointBehavior Members
public void AddBindingParameters(
  ServiceEndpoint endpoint, BindingParameterCollection bindingParameters
) { return; }

public void ApplyClientBehavior(ServiceEndpoint endpoint, ClientRuntime clientRuntime)
{
  clientRuntime.MessageInspectors.Add(new Inspector());
  foreach (ClientOperation op in clientRuntime.Operations)
    op.ParameterInspectors.Add(new Inspector());
}

public void ApplyDispatchBehavior(ServiceEndpoint endpoint, EndpointDispatcher endpointDispatcher)
{
  endpointDispatcher.DispatchRuntime.MessageInspectors.Add(new Inspector());
  foreach (DispatchOperation op in endpointDispatcher.DispatchRuntime.Operations)
    op.ParameterInspectors.Add(new Inspector());
}

public void Validate(ServiceEndpoint endpoint){ return; }
#Region "IEndpointBehavior Members"
       Public Sub AddBindingParameters(ByVal endpoint As ServiceEndpoint, ByVal bindingParameters _
                                       As BindingParameterCollection) Implements IEndpointBehavior.AddBindingParameters
           Return
       End Sub

       Public Sub ApplyClientBehavior(ByVal endpoint As ServiceEndpoint, ByVal clientRuntime As ClientRuntime) _
       Implements IEndpointBehavior.ApplyClientBehavior
           clientRuntime.MessageInspectors.Add(New Inspector())
           For Each op As ClientOperation In clientRuntime.Operations
               op.ParameterInspectors.Add(New Inspector())
           Next op
       End Sub

       Public Sub ApplyDispatchBehavior(ByVal endpoint As ServiceEndpoint, ByVal endpointDispatcher As  _
                                        EndpointDispatcher) Implements IEndpointBehavior.ApplyDispatchBehavior
           endpointDispatcher.DispatchRuntime.MessageInspectors.Add(New Inspector())
           For Each op As DispatchOperation In endpointDispatcher.DispatchRuntime.Operations
               op.ParameterInspectors.Add(New Inspector())
           Next op
       End Sub

Public Sub Validate(ByVal endpoint As ServiceEndpoint) Implements IEndpointBehavior.Validate
	Return
End Sub

Finally, the following code example shows how to modify the client configuration file to use the endpoint behavior with a particular endpoint.

  <client>
      <endpoint 
        address="http://localhost:8080/SampleService" 
        behaviorConfiguration="clientInspectorsAdded" 
        binding="wsHttpBinding"
        bindingConfiguration="WSHttpBinding_ISampleService" 
        contract="ISampleService"
        name="WSHttpBinding_ISampleService"
      >
      </endpoint>
  </client>
<behaviors>
  <endpointBehaviors>
    <behavior name="clientInspectorsAdded">
      <clientInterceptors />
    </behavior>
  </endpointBehaviors>
</behaviors>
<extensions>
  <behaviorExtensions>
    <add 
      name="clientInterceptors" 
      type="Microsoft.WCF.Documentation.InspectorInserter, HostApplication, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null"
  />
  </behaviorExtensions>
</extensions>

Remarks

Implement AfterReceiveReply to inspect or modify a reply message after it has been received by the WCF client object but before it is deserialized into objects that are returned to the client application.

The correlationState is the object returned by the user when BeforeSendRequest is called for this message. The best practice is to make this a System.Guid to ensure that no two correlationState objects are the same.
