Answer 1

Below is approach about how unsubscribe event in anonymous method:

DispatcherTimer _timer = new DispatcherTimer();
_timer.Interval = TimeSpan.FromMilliseconds(1000);
EventHandler handler = null;

int i = 0;

_timer.Tick += handler = new EventHandler(delegate(object s, EventArgs ev)
{
    i++;
    if(i==10)
        _timer.Tick -= handler;
});

_timer.Start();
