自定义的一个Behavior: 从Debug输出看到来回的Messages

就两个class, 好用又方便~

MyMessageInspector
using System;
using System.Xml;
using System.IO;
using System.ServiceModel;
using System.ServiceModel.Channels;
using System.ServiceModel.Dispatcher; 
 
namespace WCFExtentions
{
    public class MyMessageInspector : IDispatchMessageInspector
    {
        public object AfterReceiveRequest(ref Message request, IClientChannel channel, InstanceContext instanceContext)
        {
            System.Diagnostics.Debug.WriteLine(request.ToString());
            return null;
        }
 
        public void BeforeSendReply(ref Message reply, object correlationState)
        {
            System.Diagnostics.Debug.WriteLine(reply.ToString());
        }
    }
}

MyMessageInspectionBehaviorAttributeusing System; 
using System.ServiceModel; 
using System.Collections.ObjectModel; 
using System.ServiceModel.Channels; 
using System.ServiceModel.Description;
using System.ServiceModel.Dispatcher;
 
namespace WCFExtentions
{
    [AttributeUsage(AttributeTargets.Class)]
    public class MyMessageInspectionBehaviorAttribute : Attribute, IServiceBehavior   
    {
        #region IServiceBehavior Members
 
        public void AddBindingParameters(ServiceDescription serviceDescription, ServiceHostBase serviceHostBase, Collection<ServiceEndpoint> endpoints, BindingParameterCollection bindingParameters)
        {      
        }
 
        public void ApplyDispatchBehavior(ServiceDescription serviceDescription, ServiceHostBase serviceHostBase)
        {
            foreach (ChannelDispatcher channelDispatch in serviceHostBase.ChannelDispatchers)
            {
                foreach (EndpointDispatcher endpointDispatch in channelDispatch.Endpoints)
                {
                    endpointDispatch.DispatchRuntime.MessageInspectors.Add(new MyMessageInspector());
                }
            }
        }
 
        public void Validate(ServiceDescription serviceDescription, ServiceHostBase serviceHostBase)
        {
        }
 
        #endregion
    } 
}

给服务的加上这个属性, 然后你就可以在调试的时候看到了:
