次のコード例では、呼び出されるときにコンソールに文字列を書き出す基本的な IDispatchMessageInspector を示します。
#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
次のコード例では、InspectorIDispatchMessageInspector を DispatchRuntime..::.MessageInspectors に追加する IServiceBehavior の実装を示します。
#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());
}
}
}
