c# - How to dispose timer -

i have following code uses system.timers.timer:

// instance variable timer inside method timer atimer = new timer(); atimer.elapsed += new elapsedeventhandler(onelapsedtime); atimer.interval = 300000; atimer.autoreset = false; atimer.enabled = true; while (atimer.enabled) {     if (count == expectedcount)     {         atimer.enabled = false;         break;     } } 

and have following code handle event:

private static void onelapsedtime(object source, elapsedeventargs e) {     // } 

the question is: if timer event gets triggered , enters onelapsedtime, timer object stops , garbage collected? if not, can dispose of timer object/stop it? don't want timer creep , cause havoc in app.

call timer.dispose: http://msdn.microsoft.com/en-us/library/zb0225y6.aspx

private static void onelapsedtime(object source, elapsedeventargs e) {     ((timer)source).dispose(); }
