Weird things with C# events -

i'm learning events , delegates , decided write such console application. program should message me every 3 , 5 seconds. doesn't anything.

i have class workingtimer:

class workingtimer {     private timer _timer = new timer();     private long _working_seconds = 0;      public delegate void mydelegate();      public event mydelegate every3seconds;     public event mydelegate every5seconds;      public workingtimer()     {         _timer.interval = 1000;         _timer.elapsed += _timer_elapsed;                     _timer.start();     }      void _timer_elapsed(object sender, elapsedeventargs e)     {                     _working_seconds++;         if (every3seconds != null && _working_seconds % 3 == 0)             every3seconds();         if (every5seconds != null && _working_seconds % 5 == 0)             every5seconds();     } } 

and program:

class program {     static void main(string[] args)     {         workingtimer wt = new workingtimer();         wt.every3seconds += wt_every3seconds;         wt.every5seconds += wt_every5seconds;     }      static void wt_every3seconds()     {         console.writeline("3 seconds elapsed");     }      static void wt_every5seconds()     {         console.writeline("5 seconds elapsed");     } } 

so, when run doesn't anything. tried make same program in windows form application , worked great. difference in timer events elapsed , tick.

what doing wrong?

the program exits @ end of main function. try adding dummy console.readline() keep running.

the resulting code be:

static void main(string[] args) {     workingtimer wt = new workingtimer();     wt.every3seconds += wt_every3seconds;     wt.every5seconds += wt_every5seconds;     console.readline(); }
