由于“没有端点侦听”，无法连接到 NetTcpBinding WCF 服务错误

Question

你们能指出我在这里缺少什么吗？

我有两个示例项目。两个控制台应用程序（.Net 3.5）。这是“服务器”端：

class Program
{
    static void Main()
    {
        var baseAddresses = new Uri("net.tcp://localhost:9000/WcfServiceLibrary/svc");

        var host = new ServiceHost(typeof(UiWcfSession), baseAddresses);

        var reliableSession = new ReliableSessionBindingElement { Ordered = true, InactivityTimeout = TimeSpan.MaxValue };
        var binding = new CustomBinding(reliableSession, new TcpTransportBindingElement()) { ReceiveTimeout = TimeSpan.MaxValue };

        host.AddServiceEndpoint(typeof(IClientFulfillmentPipeService), binding, k.WinSvcEndpointName);
        host.Open();

        Thread.CurrentThread.Join();
    }
}

不确定它是否重要，但这里是 IClientFulfillmentPipeService 的一小段

  [ServiceContract(CallbackContract = typeof (IClientFulfillmentPipeServiceCallbacks), SessionMode = SessionMode.Required)]
  public interface IClientFulfillmentPipeService
  {
    [OperationContract(IsOneWay = true)]
    void Initialize(int uiProcessId, string key);
  }


  [ServiceContract]
  public interface IClientFulfillmentPipeServiceCallbacks
  {
    [OperationContract(IsOneWay = true)]
    void ShowBalloonTip(int timeout, string tipTitle, string tipText, BalloonTipIcon tipIcon);
  }

，最后是客户端客户

    private void OpenConnection()
    {

        try
        {
            var ep = new EndpointAddress("net.tcp://localhost:9000/WcfServiceLibrary/svc");

            var reliableSession = new ReliableSessionBindingElement {Ordered = true};

            Binding binding = new CustomBinding(reliableSession, new TcpTransportBindingElement());
            reliableSession.InactivityTimeout = TimeSpan.MaxValue;
            var pipeFactory = new DuplexChannelFactory<IClientFulfillmentPipeService>(this, binding, ep);
            commChannel = pipeFactory.CreateChannel();

            ((IChannel) commChannel).Open(OpenConnectionTimeout);
        }
        catch (Exception ex)
        {
            Log.ErrorFormat("The communication channel to the windows service could not be established.  {0}", ex.Message);
        }
    }

端失败，并出现 System.ServiceModel.EndpointNotFoundException 异常，其中显示： < em>“在 net.tcp://localhost:9000/WcfServiceLibrary/svc 上没有监听可以接受消息的端点。这通常是由不正确的地址或 SOAP 操作引起的。请参阅 InnerException，如果存在，请了解更多详细信息。”

这是使用命名管道的生产代码的修改，我想将其转换为 Tcp 传输。

谢谢！

我不小心将 k.WinSvcEndpointName 留在了服务器的端点定义中。这就是问题所在。
