timer that runs 2 of every 3 seconds c# -

is there way run program every 2 of 3 seconds? know can make timers run every n milliseconds, not every n of m seconds. basic example, pretend want have 2 functions both add integer value. 1 function run 2 of every 3 seconds , add 5 value. second function add 100 same value, run 1 second other 1 doesn't run. make sense?

the simplest way keep internal representation of second on , switch based on different execution.

private int counter = 0; private int whichsecond = 0;  void runseverysecond() {     if (whichsecond < 2)     {         counter += 5;         whichsecond++;     }     else     {         counter += 100;         whichsecond = 0;     } }
