Timer tick event continue or exit

Question

I wonder the problem, is when I call the Timer event:

DispatcherTimer Timer = new DispatcherTimer();
                Timer.Tick += (s, e) =>
              {
               
                  MyCode();
                  Timer.Stop();
              };

Timer.Start();
Timer.Interval = TimeSpan.FromSeconds(10);

private static void MyCode() { /* EXAMPLE MY CODE RUN */ }

So will my MyCode run out of thread before Timer.Stop() or not?

Answer 1

There are a few problems with your code:

• You start the timer before you set the interval, so the Tick event will be triggered immediately rather than after 10 sec.
• The DispatcherTimer does not have a Close method. You probably mean Stop?
• In the Tick event, you call MyCode before you stop the Timer. It is probably better to first stop the Timer, before you call MyCode.

So a suggestion for your code:

DispatcherTimer Timer = new { Interval = TimeSpan.FromSeconds(10) };
Timer.Tick += (s, e) =>
          {               
              Timer.Stop();
              MyCode();
          };
Timer.Start();
...

private static void MyCode() { /* EXAMPLE MY CODE RUN */ }
