timer.Interval = TimeSpan.FromMilliseconds(1); This is insane. You think you can see one millisecond ? 30 milliseconds is WAY too short. And why have a timer if you're going to use a counter inside it ? Why not set the timer to 500 milliseconds and just swap every time ?

25 Nov 2009 by AspDotNetDev

You are setting isRunning to true after the first iteration. Since the if statement inside your for loop checks isRunning, it will skip over all but the first item in the for loop.When you say timer.Start(), the greenCount() method will never actually be reached until the timer() method has comple
