Question

我搜索并搜索了Windows服务信息，它几乎不存在或过时。此外，VS 2013中没有Windows服务模板（我可以找到）。

我正在制作一个简单的性能监视器，它将CPU和RAM记录到文本文件中。我跟着几本过时的教程，自己想出了一些东西。

当我尝试通过F5（同事的建议）运行时，命令提示符闪烁打开，关闭然后程序结束。我认为不会调用OnStart方法。

我可以从VS命令提示符处安装好服务但是在尝试启动该过程时，我收到一个错误，它没有及时启动。我甚至尝试在服务管理器中启用与桌面的交互。

我也尝试过Debug和Release版本。

我已经查看了其他SO问题，建议在OnStart方法中进行所有初始化，我认为我做了（虽然我可能错了 - 我显然还在学习）。

相关代码：

namespace SystemMonitorD
{
    public class SystemMonitorD : ServiceBase
    {
        private Timer StateTimer { get; set; }
        private TimerCallback TimerDelegate { get; set; }
        private SystemMonitorL SysMon { get; set; }

        public SystemMonitorD()
        {
            ServiceName = "SystemMonitorD";
            CanStop = true;
            CanPauseAndContinue = true;
            AutoLog = true;
        }


        protected override void OnStart(string[] args)
        {
            SysMon = new SystemMonitorL();
            TimerDelegate = SysMon.Log;
            StateTimer = new Timer(TimerDelegate, null, SysMon.WaitTime, SysMon.WaitTime);
        }

        protected override void OnStop()
        {
            SysMon.StatusLog("Stop");
            StateTimer.Dispose();
        }

        protected override void OnPause()
        {

在调试Windows服务时，让生活更轻松的一件事就是为您的服务使用Debug \ Release标志。单步作为非服务的逻辑。

static void Main()
{
#if (!DEBUG)
    //RELEASE FLAG  
    System.ServiceProcess.ServiceBase[] ServicesToRun;
    ServicesToRun = new System.ServiceProcess.ServiceBase[] { new MyService() };
    System.ServiceProcess.ServiceBase.Run(ServicesToRun);
#else
    //DEBUG                
    MyService service = new MyService(); //<--Put breakpoint here before you run your service
    service.OnStart(null);    
    System.Threading.Thread.Sleep(System.Threading.Timeout.Infinite);
#endif 
}

我发现了我的问题。我失踪了我的Main（）方法中的ServiceBase.Run(new SystemMonitorD());。这解决了这个问题。我是从this MSDN link找到的。
