Programming against an enum in a switch statement, is this your way to do?

Question

Look at the code snippet:

This is what I normally do when coding against an enum. I have a default escape with an InvalidOperationException (I do not use ArgumentExc

Answer 1

I would suggest to use either NotImplementedException or better a custom DrivingStateNotImplementedException if you like to throw exceptions.

Me, I would use a default drivingstate for default (like neutral/stop) and log the missing driverstate (because it's you that missed the drivingstate, not the customer)

It's like a real car, cpu decides it misses to turn on the lights, what does it do, throw an exception and "break" all control, or falls back to a known state which is safe and gives a warning to the driver "oi, I don't have lights"
