Operation of timers in C #

We can use the stopwatch class to get the running time of the program, and when optimizing the code, you can use this method to view the time spent by the program before and after optimization

Static voidMain (string[] args) {Stopwatch SW=NewStopwatch (); Longnum =0; Sw.    Reset (); SW=stopwatch.startnew ();  for(inti =1; I <100000000; i++) num + =1; Sw.    Stop (); TimeSpan El=SW.    Elapsed; Console.WriteLine ("cost {0}", EL); Longms =SW.    Elapsedmilliseconds; Console.WriteLine ("cost {0} milliseconds", MS); LongTK =SW.    Elapsedticks; Console.WriteLine ("cost {0} ticks", TK); Console.readkey ();}
