我正在编写托管在 Windows 服务中的 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。您能否帮我查看代码,以及我如何即兴创作它:- 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)。

我应该如何:- 1. 定义 Windows 服务依赖项(它应该在机器连接到互联网之前启动)。2. 应该怎么多容错,隔了一段时间怎么启动。

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);
                }
                EnLog.Source = ServiceName;
                EnLog.Log = logName;
            }

            protected override void OnStart(string[] args)
            {
                if (serviceHost != null)
                {
                    serviceHost.Close();
                }
                EnLog.WriteEntry(ServiceName + " Inside OnStart...");
                try
                {
                   serviceHost = new ServiceHost(typeof(InsightSrcDataService));

                    serviceHost.Faulted += HostFaulted;
                    serviceHost.UnknownMessageReceived += HostUnknownMessageReceived;

                    serviceHost.Open();
                    LogServiceInfo(serviceHost);
                    if (serviceHost.State != CommunicationState.Faulted)
                    {
                        EnLog.WriteEntry(ServiceName + " started successfully.");
                        EnLog.WriteEntry(ServiceName + " Automapping of entities are done successfully.");
                    }
                }
                catch (Exception ex)
                {
                    string msg = ServiceName + " failed to start. Exception Message:-" + ex.Message + (ex.InnerException != null ? ex.InnerException.Message : string.Empty);
                    EnLog.WriteEntry(msg);
                    Logger.LogException(NLog.LogLevel.Error, msg, ex);
                }
            }

            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.");
            }

            private void HostFaulted(object sender, EventArgs e)
            {
                EnLog.WriteEntry(ServiceName + " - Host Faulted.");
            }

            protected override void OnStop()
            {
                if (serviceHost == null) return;
                serviceHost.Close();
                serviceHost = null;
            }
        }
    }

这有时会引发以下异常(我猜它缺少 Windows 服务依赖性,我希望在机器连接到互联网和 sql 服务器服务启动后启动此服务)。

  1. System.TimeoutException:打开操作未在分配的 00:00:00 超时内完成。分配给此操作的时间可能是较长超时的一部分。---> System.TimeoutException:在 00:00:00 之后打开超时,同时建立到 net.tcp://xxx.servicebus.windows.net:9351/Src/guid/ 的传输会话。分配给此操作的时间可能是较长超时的一部分。---> System.TimeoutException:通过 net.tcp://xxx.servicebus.windows.net:9351/Src/guid/ 连接到 00:00:00 后超时。对 1 个可用地址中的 0 个进行了连接尝试 ()。检查您的通道的 RemoteAddress 并验证此端点的 DNS 记录是否对应于有效的 IP 地址。分配给此操作的时间可能是较长超时的一部分。在 System.ServiceModel.Channels。

那么第二个错误意味着您正在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您使用的是正确的密钥。

看起来像 NetTCPRelaybinding 实现中的错误。我也有同样的问题。我中继服务总线的部分,我可以看到正在显示的服务,但中继类型为无。
