Question

Pseudo-situation: have a class (let’s say BackgroundMagic), and it has Start() and Stop() methods. The work in this class is done by one single thread, and is simply a short loop every X milliseconds.

Which of these options is better, as far as managing the stopping/starting? Can’t decide which road to take.

1. The first time Start() is called, initialize and start the thread with IsBackground = true. Use a simple bool flag to indicate on each loop around whether it should actually do any work, or just sleep. After initial initialization, let Stop() and Start() simply control the bool flag. The thread will just be stopped and cleaned up by the runtime since IsBackground = true when the app exits.
2. Forcefully abort/join/interrupt/whatever on Stop, and recreate the thread again on Start(), not leaving the thread lying around.

… or any better/cleaner ways of doing this?

Answer 1

Neither! Use a Thread Pool!
