测试Remoting服务端和客户端的双向通信

最近有个项目，大致需求是，服务端发送消息通知客户端上传指定的数据，然后处理后一部分显示在服务端界面上。也是在网上胡乱搜索一片，看到一篇Remoting广播事件的博客+Remoting觉得这么还可以做。

大致原理是：通过服务端广播事件，客户端通过调用远程类将数据以参数的方式传给服务端，然后激活服务端界面层的事件就达到双向了。都是靠远程类里的2个事件，一个给服务端，一个给客户端，分别交叉执行。这就相当于： 服务端界面--远程类--客户端界面，远程类起到了一个中间人的作用样，是吧？

 

先看看服务端封装的Remoting的类

 

public sealed class RemotingServer
    {
        HttpChannel tcpC;

        public static RemotingObject.Remoter Obj = null;

        static RemotingServer instance = new RemotingServer();

        public static RemotingServer GetRemotingServer
        {
            get { return instance; }
        }

        RemotingServer()
        {
            //tcpC = new TcpChannel(9000);
            
        }

        public void ServerTakeOn()
        {
            //if (!ExistServer(tcpC.ChannelName))
            //{
                RemotingConfiguration.RegisterWellKnownServiceType(typeof(RemotingObject.Remoter), "RemotingService", WellKnownObjectMode.Singleton);
                BinaryServerFormatterSinkProvider serverProvider = new BinaryServerFormatterSinkProvider();
                BinaryClientFormatterSinkProvider clientProvider = new BinaryClientFormatterSinkProvider();
                serverProvider.TypeFilterLevel = TypeFilterLevel.Full;
                IDictionary props = new Hashtable();
                props["port"] = 9500;
                tcpC = new HttpChannel(props, clientProvider, serverProvider);
                ChannelServices.RegisterChannel(tcpC);

                Obj = new RemotingObject.Remoter();
                ObjRef objRef = RemotingServices.Marshal(Obj, "RemotingMessage.soap");
            
            //}
        }

        public void ServerTakeOff()
        {
            if (ExistServer(tcpC.ChannelName))
            {
                tcpC.StopListening(null);
                ChannelServices.UnregisterChannel(tcpC);
            }
        }

        private bool ExistServer(string serverName)
        {
            bool tmp_b = false;
            IChannel[] list = ChannelServices.RegisteredChannels;
            foreach (IChannel ic in list)
            {
                HttpChannel tmp_tcp = (HttpChannel)ic;
                if(tmp_tcp.ChannelName==serverName)
                {
                    tmp_b = true;
                    break;
                }
            }
            return tmp_b;
        }
    }
