I'm creating this simple windows service to play a beep every six seconds. When I Start it on Debug Mode, it simply stops right after the start. There seem to be no errors or exceptions.

 public partial class Service1 : ServiceBase
    {
        static Timer myTimer;
        public Service1()
        {
            InitializeComponent();
        }

        public void OnDebug() 
        { 
            OnStart( null );
        }

        protected override void OnStart( string[] args )
        {

            myTimer = new Timer();
            myTimer.AutoReset = true;
            myTimer.Interval = 60000;
            myTimer.Enabled = true;
            myTimer.Start();

            myTimer.Elapsed  = new ElapsedEventHandler( OnTimedEvent );

        }

        private static void OnTimedEvent( object sender, ElapsedEventArgs e )
        {
                SystemSounds.Beep.Play();
        }

        protected override void OnStop()
        {
        }


    }

My main method

static void Main()
    {
        #if DEBUG
            Service1 testService = new Service1();
            testService.OnDebug();

        #else
            ServiceBase[] ServicesToRun;
            ServicesToRun = new ServiceBase[]
            {
                new Service1()
            };
            ServiceBase.Run(ServicesToRun);
        #endif
    }

The beep works fine on itself. But it doesn't work with timer.

CodePudding user response：

You need to keep on running your service, you can add this code after line testService.OnDebug();. It will make your service run until you press q.

Console.WriteLine("Press \'q\' to quit the sample.");
while (Console.Read() != 'q') ;
