stop timer after interval time in c#

Question

I am using .net compact framework 3.5 in visual studio 2008.

I have created a timer tick event to perform a job.I want to call the timer only once and after that i need to disable the timer.Please see my below code

   int counter = 0;
        var timer = new Timer { Enabled = true, Interval = 10000 };
        timer.Tick += delegate
        {
            Cleanup();
        };
        counter++;
        if (counter >= 1)
        {
            timer.Enabled = false;
        }

I tried with timer.Enabled = false; without any condition,what happens is the Cleanup() function is not calling which is inside the tick event.So from google i got one more solution to use a counter.With counter also i am facing the same problem, Cleanup() is not calling.

If i am not disable the timer,then the function is calling in every 10secs time.I need to call the Cleanup() function only once,which is inside the timer.tick.Need help to solve this.

Thanks

Answer 1

Why do you need a counter:

This should be enough

timer.Tick += delegate
{
   timer.Enabled = false;
   Cleanup();
};

Another approach if you are using System.Timers.Timer - use Timer.AutoReset to make it fire only once:

var timer = new System.Timers.Timer(10000) { AutoReset = false };
timer.Elapsed += (s,e)=>Cleanup();
timer.Enabled = true;

Answer 3

Short notation using lambda:

var timer = new Timer { Enabled = true, Interval = 10000 };
timer.Tick +=()=>{ timer.Enabled=false; Cleanup();};
