当按下取消键（CTRL + C）强制停止服务时，控制台中的顶架

Question

I would like that Topshelf stops my service when I debug it in a console.

My code:

public class Program
{
    private static ILog _log = LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);

    public static void Main(string[] args)
    {
        HostFactory.Run(Configure);
    }

    /// <summary>
    /// Configures the service host.
    /// </summary>
    /// <param name="cfg">The HostConfigurator</param>
    private static void Configure(HostConfigurator cfg)
    {
        try
        {
            cfg.Service<ServiceHost>(s =>
            {
                s.ConstructUsing(name => new ServiceHost());
                s.WhenStarted(host => host.StartService());
                s.WhenStopped(host => host.StopService());
            });

            cfg.RunAsLocalSystem();
            cfg.StartManually();
            cfg.SetDisplayName(DisplayName);
            cfg.SetServiceName(ServiceName);
            cfg.UseLog4Net();
        }
        catch (Exception ex)
        {
            _log.Fatal("Exception on Startup", ex);
            throw;
        }
    }
}

But when I press CTRL+C it hangs in Microsoft.VisualStudio.HostingProcess.HostProc.WaitForThreadExit .

When I press CTRL+C I would like that host => host.StopService() is called immediately.

Is that possible?

Answer 1

通过向Console.CancelKeyPress事件添加事件处理程序，应该可以拦截CTRL + C：

Console.CancelKeyPress += (s, e) => host.StopService();

Answer 2

The most likely culprit is that your service's StartService method doesn't return control to Topshelf. What does your StartService do? It should only initialize any resources and start up your event loop/thread. Can you run service install start and get it to start up? If the service times out while starting up, it would also reinforce the idea that your start isn't returning.

its a known bug with .NET 4.0, there is a workaround but its nasty

Answer 4

In VS2010, you need to:

1. Go to your project property, then navigate to Debug pane, check 'Enable unmanaged code debugging'.
2. Toolbar Debug-> Exceptions -> then Uncheck the C++ Exceptions and the Win32 Exceptions.

Answer 5

在ServiceHost类中实现IDisposeable，添加Dispose方法，并处置所有线程对象。
