In the previous lesson, Handling Clicks at Coordinates in C# .NET, we completed the application that rendered geometric shapes on a PictureBox. In today's C# .NET tutorial we're going to learn how to use Timer and BackgroundWorker. We'll test both controls on illustrative examples.

Form Application Loop

If you remember our console tutorials, we simply put code in a loop if we wanted to repeat it. If we wanted to countdown 10 seconds, the console code would look like this:

for (int i = 10; i > 0; i--)
