喂我需要一个Tcp连接到一个在backgrond中活着的服务器，应用程序将使用此连接发送数据。我搜索了周围，发现WCF单例适用于此任务这是我在下面使用的代码片段我的问题是好的方法和任何问题都可能与此有关吗？

 string hostAddress = string.Empty;
           try
            {
                srvHost = new ServiceHost(typeof(ControllerClass));
                NetTcpBinding netTcpBinding = new NetTcpBinding(SecurityMode.None);
                netTcpBinding.Security.Message.ClientCredentialType = MessageCredentialType.None;
                netTcpBinding.Security.Transport.ProtectionLevel =      System.Net.Security.ProtectionLevel.None;
                netTcpBinding.Security.Transport.ClientCredentialType = TcpClientCredentialType.None;

                srvHost.AddServiceEndpoint(typeof(IControllerContract), netTcpBinding, hostAddress);
                srvHost.Credentials.WindowsAuthentication.AllowAnonymousLogons = true;

                ServiceThrottlingBehavior serviceThrottlingBehavior = new ServiceThrottlingBehavior();
                serviceThrottlingBehavior.MaxConcurrentCalls = 1000;
                serviceThrottlingBehavior.MaxConcurrentInstances = 1000;
                serviceThrottlingBehavior.MaxConcurrentSessions = 1000;
                srvHost.Description.Behaviors.Add(serviceThrottlingBehavior);
                srvHost.Open();
            }
            catch (System.TimeoutException timeoutEx)
            {

                Thread.Sleep(1000);
                ReOpenHostConnection();//initialize again Controller Class
            }
            catch (Exception ex)
            {
                Trace.WriteLine(string.Format("cannot start Service Ex:{0}", ex.ToString()), TraceEventType.Error.ToString());
            }

//Controller Class Initialize Code Snippet

TcpClient iTcpClient = new TcpClient();
                iTcpClient.Connect(serverIP, serverPort);
                networkStream = iTcpClient.GetStream();
                aSychDataByte = new byte[iTcpClient.ReceiveBufferSize];
                networkStream.BeginRead(aSychDataByte, 0, incommTcpClient.ReceiveBufferSize, ReadAsych, null);

为什么要将TcpClient与WCF结合使用？如果您需要基于低级别Tcp类的低级别Tcp通信构建客户端和服务器。如果您需要服务而且不打扰消息格式，请使用WCF。

为了你的问题。你不需要单身人士。您只需要打开连接即可。为此，您需要在客户端上创建WCF代理实例（开放通道）并调用该服务。它将创建与服务实例的连接，直到您关闭客户端代理，直到您的服务主机停止工作或超时（默认情况下客户端不活动10分钟）。

保持与WCF的TcpClient连接
