Answer 1

Environment.Exit() is a rude abort. It instantly terminates the process. Use it only when you detect a gross failure, it is appropriate in an AppDomain.UnhandledException event handler for example. Which runs when your program is about to terminate because of an unhandled exception.

Which is your lead: exceptions are a good way to signal unusual conditions that should terminate the program with an ExitCode that isn't zero. In fact, it automatically gets set to the HResult property value of the exception. No code required.
