Difference between Abort and Interrupt in Threads in .NET

Question

What is the difference between Thraed.Abort() and Thread.Interrupt(). How can I call them in a Thread Safe Manner.It would be helpful,if simple example is provided.

Answer 1

Unless you're calling Abort or Interrupt on the currently executing thread (as ASP.NET does to terminate a request abruptly, for example) you basically can't call them in a thread-safe manner.

Use a WaitHandle or Monitor.Wait/Pulse to wait in a wakeable way. You should only abort other threads if you're tearing down the application, basically - as otherwise you can end up in an unknown state.

See my article on graceful thread termination for an example of how to do this nicely.
