Replace Dispatcher timer with timer

Question

Hi,

What is the similar code of dispatcher timer but with timer.

private IDispatcherTimer _timer;

protected override void OnAppearing()

{

  base.OnAppearing();



 MainThread.BeginInvokeOnMainThread(() =>

  {

      SetIndicatorStatus();

      SetTimer();

  });

 if (_timer == null)

  {

     var dispatcher = this.Dispatcher;

      _timer = dispatcher.CreateTimer();

     _timer.Interval = TimeSpan.FromSeconds(30);

      _timer.Tick += (s, e) =>

      {

          MainThread.BeginInvokeOnMainThread(() =>

          {

           SetIndicatorStatus();

             SetTimer();

          });

     };

     _timer.IsRepeating = true;

      _timer.Start();

  }

}

protected override void OnDisappearing()

{

  base.OnDisappearing();

 if (_timer != null)

  {

     _timer.Stop();

  }

}

Hello,

You can replace DispathTimer with the following code equivalent via Timer.

   private Timer _timer;

   protected override void OnAppearing()
    {

       base.OnAppearing();
        MainThread.BeginInvokeOnMainThread(() =>
        {
            SetIndicatorStatus();
            SetTimer();
        });


       if (_timer == null)
        {
            _timer = new System.Threading.Timer(TimerFunction,null,0, 30000);
        }
    }
    private void TimerFunction(Object stateInfo)
    {
        MainThread.BeginInvokeOnMainThread(() =>
        {
            SetIndicatorStatus();
            SetTimer();
        });
    }
    protected override void OnDisappearing()
    {

       base.OnDisappearing();

       if (_timer != null)

       {

           _timer.Dispose();

       }
    }
