How can one set up a thread in C# to only execute when CPU is idle?

Question

I have a Windows Service in C#. I want a certain thread to perform specific actions, but only when the CPU is idle. Is there a way to do this in C#.

Answer 1

You can let the OS handle it for you like this:

Thread thread = Thread.CurrentThread;
thread.Priority = ThreadPriority.Lowest;

Answer 2

Try setting ThreadPriority to BelowNormal or less. See MSDN.
