Question

我正在编写Windows服务中托管的netTcpRelayBinding WCF服务。由于缺乏Windows服务开发经验，我觉得我的代码很幼稚。这是从Windows-Azure调用的。你能帮我看一下代码，以及我如何即兴发布： - 我们正在使用NLOG进行日志记录。

我的服务抛出异常（在问题末尾提到）。

我应该怎样： - 1.定义Windows服务依赖项（应该在机器获取之前启动）连接到互联网）。 2.它应该如何更具容错性，如何在一段时间间隔后启动。

namespace XYC.Service.WinServiceHost
    {
        public partial class XYCService : ServiceBase
        {
            private ServiceHost serviceHost = null;
            private static readonly NLog.Logger Logger = NLog.LogManager.GetCurrentClassLogger();
            public One23InsightService()
            {
                // Name the Windows Service
                ServiceName = "XYCService ";
                const string logName = "Application";
                InitializeComponent();
                if (!System.Diagnostics.EventLog.SourceExists(ServiceName))
                {
                    System.Diagnostics.EventLog.CreateEventSource(ServiceName, logName);

                }
            }

            private void LogServiceInfo(ServiceHost host)
            {
                EnLog.WriteEntry(host.Description.ServiceType + "is up and running with these endpoints :");
                foreach (ServiceEndpoint se in host.Description.Endpoints)
                {
                    EnLog.WriteEntry(se.Address.ToString());
                }
            }

            private void HostUnknownMessageReceived(object sender, UnknownMessageReceivedEventArgs e)
            {
                EnLog.WriteEntry(ServiceName + " Inside UnknownMessageReceived.");
            }

            {
                EnLog.WriteEntry(ServiceName + " - Host Faulted.");
            }

                serviceHost = null;
            }
        }
    }

这有时会抛出以下异常（我猜它缺乏Windows服务依赖性，我希望在机器连接到Internet并启动sql server服务后启动此服务。）

Answer 1

第二个错误意味着您使用的命名空间的颁发者密钥不正确。您可能需要检查以确保使用正确的密钥。

Answer 2

看起来像是NetTCPRelaybinding实现中的一个错误。我也有同样的问题。我转发Servicebus的部分，我可以看到正在显示的服务但是relaytype是None。
