Question

C# What is the easiest way to disable a control after 10 seconds? Using a Timer or a stopwatch? I'm new to both so thanks for the help.

Answer 1

Use a timer. It suits your needs better.

EDIT: As other have said, go with the System.Windows.Forms.Timer

Answer 2

I'm not sure how you'd expect stopwatch to help. A timer certainly sounds like the right answer to me. You should be aware that there are several different timers available - in this case System.Windows.Forms.Timer is probably the one you want for a WinForms app, or a System.Windows.Threading.DispatcherTimer for WPF.

Answer 3

Windows forms has a Timer control (here's WPF's version).

The reason why you use these is because these timers fire on the UI thread, so you don't have to do the usual multithreaded if-InvokeRequried-Invoke dance that you would have to do if you used System.Threading.Timer or some other method that ran on a different thread.

Answer 4

Related to @Jon Skeet's answer, the reason you want the System.Windows.Forms.Timer timer (out of the 3 in the framework) is that it will take care of executing your timer code on the UI thread for you. The other timers don't do that for you so you're left to calling .CanInvoke and Invoke() all over (or using a SynchronizationContext which is a bit simpler, but still cumbersome).
