DispatcherTimer not firing Tick event

I have a DispatcherTimer i have initialised like so:

static DispatcherTimer _timer = new DispatcherTimer();

static void Main()
    _timer.Interval = new TimeSpan(0, 0, 5);
    _timer.Tick += new EventHandler(_timer_Tick);
static void _timer_Tick(object sender, EventArgs e)
    //do something

The _timer_Tick event never gets fired, have i missed something?


If this is your main entry point, it's likely (near certain) that the Main method exits prior to when the first DispatcherTimer event could ever occur.

As soon as Main finishes, the process will shut down, as there are no other foreground threads.

That being said, DispatcherTimer really only makes sense in a use case where you have a Dispatcher, such as a WPF or Silverlight application. For a console mode application, you should consider using the Timer class, ie:

static System.Timers.Timer _timer = new System.Timers.Timer();

static void Main()
    _timer.Interval = 5000;
    _timer.Elapsed  += _timer_Tick;
    _timer.Enabled = true;

    Console.WriteLine("Press any key to exit...");
    Console.ReadKey(); // Block until you hit a key to prevent shutdown
static void _timer_Tick(object sender, ElapsedEventArgs e)
    Console.WriteLine("Timer Elapsed!");

because the main method thread ended before the tick was called.

You missed Application.Run(). Tick events cannot be dispatched without the dispatcher loop. A secondary issue is that your program immediately terminates before the event ever could be raised. Application.Run() solves that too, it blocks the Main() method.

You have to start a dispatcher in order for the dispatcher to "do" any events. If you are running inside of a WPF application, this should happen automatically. If you are running in a console (which it looks like), this will never fire because there isn't a dispatcher. The easiest thing you can do is try this in a WPF application and it should work fine.

You have to use

static void DispatcherTimer_Tick(object sender, object e)


in the place of timer_tick event
