Socket#33711845::DoBind 中的异常 - 通常只允许每个套接字地址（协议/网络地址/端口）使用一次

Question

我正在尝试设置一个简单的远程 Windows 服务，并在启动该服务时出现以下错误：

System.Net.Sockets Error: 0 : [4180] Exception in the Socket#33711845::DoBind - Only one usage of each socket address (protocol/network address/port) is normally permitted
System.Net.Sockets Verbose: 0 : [4180] ExclusiveTcpListener#4032828::Start()
System.Net.Sockets Verbose: 0 : [4180] Socket#33711845::Bind(0:9998#9998)
System.Net.Sockets Error: 0 : [4180] Exception in the Socket#33711845::DoBind - Only one usage of each socket address (protocol/network address/port) is normally permitted

在 Windows 服务应用程序中，我在“OnStart”方法中有以下代码 - 注册通道时发生错误 - ChannelServices.RegisterChannel( tcpPipe，真）；据我所知，没有其他进程使用端口 9998 ...

   protected override void OnStart(string[] args)
    {

        int portNumber = int.Parse(ConfigurationManager.AppSettings["endPointTCPPort"]);

        TcpChannel tcpPipe = new TcpChannel(portNumber);

        ChannelServices.RegisterChannel(tcpPipe, true);

        Type serviceType = Type.GetType("TractionGatewayService.TractionGateway");

        try
        {
           RemotingConfiguration.RegisterWellKnownServiceType(serviceType, "updateCustomerDetails", WellKnownObjectMode.SingleCall);
        }
        catch (RemotingException e)
        {
            EventLog.WriteEntry("unable to establish listening port because " + e.message; 
            ChannelServices.UnregisterChannel(tcpPipe);
        }

我已经找到问题了。我对 TcpChannel 进行了两次单独的调用来注册端口 - 因此出现了错误。
