c# - Timer resets after 60 seconds -

below code i'm attempting use elapsed timer on desktop task timer we're building. right when runs counts 60 seconds , resets , doesn't ever add minutes.

//tick timer checks see how long agent has been sitting in misc timer status, reminds them after 5 mintues ensure correct status used private void statustime_tick(object sender, eventargs e) {     counter++;     //the timespan handle push elapsed time in seconds label can update user     //this shouldn't require background worker since it's small app , nothing resource heavy      var timespan = timespan.fromseconds(actualtimer.elapsed.seconds);      //convert time in seconds format requested user     displaycounter.text=("elapsed time in " + statusname+" "+ timespan.tostring(@"mm\:ss"));      //pull thread updating ui     application.doevents();  } 

quick fix

i believe problem using seconds 0-59. want use totalseconds existing code:

var timespan = timespan.fromseconds(actualtimer.elapsed.totalseconds);

comments

however, doesn't make lot of sense use timespan object directly:

var timespan = actualtimer.elapsed; 

also, can't see application, expect not need call application.doevents();. ui should update automatically when has chance... if doesn't want @ moving whatever code blocking ui different thread.

recommendation

with said, recommend don't use timer track elapsed time @ all. timers can lose accuracy on time. best approach store current system time when start process, when need display 'timer' on-demand calculation @ point.

a simple example explain mean:

datetime start;  void starttimer() {     start = datetime.now; }  void updatedisplay() {     var timespan = datetime.now.subtract(start);     displaycounter.text = "elapsed time in " + statusname + " " + timespan.tostring(@"mm\:ss")); } 

you use timer call updatedisplay method @ regular intervals:

void statustime_tick(object sender, eventargs e) {     updatedisplay(); }
