Use System.Threading.Timer wherein you can specify how much time should pass until the timer fires, and what code to execute when the timer does fire.

You can also look at the System.Windows.Forms.Timer.

For a comparison of all the timer-like classes in .NET, check out Comparing the Timer Classes in the .NET Framework.

Use timers from System.Timer or System.Threading .Timer depends upon your needs. and execute your code in each interval.

have a look at

and

if its a simple winforms app like u mentioned its a countdown app consider Forms.Timer its easier to implement. Just drag and drop the control from toolbox and perform countdown in Tick Event. have a look for it here:
