But this will trash the CPU performance. This ex

Why don't you write a small application and use the system's task scheduler to run it every minute, hour...etc?

Another option would be to write a Windows Service which runs in the background. The service could use a simple Alarm class like the following on MSDN:

You can use it to periodically trigger your method. Internally this Alarm class uses a timer:

Just set the timer's interval correctly (e.g. 60000 milliseconds) and it will raise the Elapsed event periodically. Attach an event handler to the Elapsed event to perform your task. No need to implement an "infinite loop" just to keep the application alive. This is handled for you by the service.
