remoting动态加载dll，客户端提示“找不到请求的服务”

Question

我在AppDomainLoader创建AppDomain，在RemoteLoader使用assembly，然后在windows服务里启动，现在问题是服务端启动没有错误，但在客户端iTest = (ITest)(Activator.GetObject(typeof(ITest), "tcp://localhost:8989/Test")); Response.Write(iTest.Hello());运行到输出时提示“找不到请求的服务”，Response.Write(iRemote.GetType().ToString());得到的是System.MarshalByRefObject.

我将windows服务移植到控制台应用程序上，逐步运行下来，在Assembly _assembly = Assembly.LoadFrom(url);
            Type[] t = _assembly.GetExportedTypes();可以得到类的名称。

网上找了好久，好像是说客户端得不到远程的。个人怀疑是不是服务端的assembly没有work，不过不知道该怎样修改。下面贴下服务端代码：

 

 BinaryClientFormatterSinkProvider cbin = new BinaryClientFormatterSinkProvider();
                    BinaryServerFormatterSinkProvider sbin = new BinaryServerFormatterSinkProvider();
                    sbin.TypeFilterLevel = System.Runtime.Serialization.Formatters.TypeFilterLevel.Full;

                    Hashtable properties = new Hashtable();
                    properties["port"] = dt.Rows[i]["Port"].ToString();

                    TcpChannel channel = new TcpChannel(properties, cbin, sbin);
                    ChannelServices.RegisterChannel(channel, false);

                    DataTable dTable = _remoteManager.RemoteList();
                    for (int j = 0; j < dTable.Rows.Count; j++)
                    {
                        //得到dll文件保存路径
                        string url = filename + dTable.Rows[j]["Key"].ToString();
                        AppDomainLoader appDomain = new AppDomainLoader();
                        appDomain.CreateAppDomain(url);
                    }

 

 

 

public void CreateAppDomain(string url)
        {
            AppDomainSetup setup = new AppDomainSetup();
            setup.ShadowCopyFiles = "true";
            setup.DisallowBindingRedirects = false;
            setup.DisallowCodeDownload = true;
            setup.ConfigurationFile =
                AppDomain.CurrentDomain.SetupInformation.ConfigurationFile;

            //创建程序域
            string aname = Assembly.GetExecutingAssembly().GetName().FullName;
            AppDomain appDomain = AppDomain.CreateDomain(url, null, setup);

           
            ht.Add(url, appDomain);
            //在创建的程序域中读取
            RemoteLoader test = (RemoteLoader)appDomain.CreateInstanceAndUnwrap(aname, "Explorer.Framework.Service.RemoteLoader");
            test.StartAssembly(url);
        }

 

 

 public void StartAssembly(string url)
        {
            Assembly _assembly = Assembly.LoadFrom(url);
            Type[] t = _assembly.GetExportedTypes();
            foreach (Type type in t)
            {
                RemotingConfiguration.RegisterWellKnownServiceType(type, type.Name, WellKnownObjectMode.SingleCall);
            }

        }
