                var service = new MyService();
                service.OnStart(null);

                // Sleep the main thread indefinitely while the service code
                // runs in .OnStart

                Thread.Sleep(Timeout.Infinite);
#else
                // Run normally as service in release mode.

                ServiceBase[] ServicesToRun;

您也可以通过命令提示符(sc.exe)启动服务。

就我个人而言，我会在调试阶段将代码作为独立程序运行，当大多数错误被解决后，再改为作为服务运行。

我能够轻松地调试一个windows服务从微软官方文档- https://learn.microsoft.com/en-us/dotnet/framework/windows-services/how-to-debug-windows-service-applications#how-to-run-a-windows-service-as-a-console-application。

它告诉运行windows服务作为控制台应用程序进行调试。

下面是我用来测试服务的简单方法，没有任何额外的“调试”方法，并带有集成的VS单元测试。

[TestMethod]
public void TestMyService()
{
    MyService fs = new MyService();

    var OnStart = fs.GetType().BaseType.GetMethod("OnStart", BindingFlags.NonPublic | BindingFlags.Public | BindingFlags.Instance | BindingFlags.Static);

    OnStart.Invoke(fs, new object[] { null });
}

// As an extension method
public static void Start(this ServiceBase service, List<string> parameters)
{
     string[] par = parameters == null ? null : parameters.ToArray();

     var OnStart = service.GetType().GetMethod("OnStart", BindingFlags.NonPublic | BindingFlags.Public | BindingFlags.Instance | BindingFlags.Static);

     OnStart.Invoke(service, new object[] { par });
}

最好的选择是使用“系统”。诊断的名称空间。

将代码包含在if else块中，用于调试模式和发布模式，如下所示，在visual studio中切换调试和发布模式。

#if DEBUG  // for debug mode
       **Debugger.Launch();**  //debugger will hit here
       foreach (var job in JobFactory.GetJobs())
            {
                //do something 
            }

#else    // for release mode
      **Debugger.Launch();**  //debugger will hit here
     // write code here to do something in Release mode.

#endif
