C# What is the best way to create an enum that is used by multiple classes?

Question

I have an enum which is used by multiple classes. What is the best way to implement this?

Answer 1

Typically I just throw them into the namespace. It's what Microsoft did writing the .NET framework, so it's what I do too, for consistency you understand :)

Answer 2

1. Put the enums right in your namespace (or make a new namespace for them) or
2. Put them in a (static?) class somewhere if that makes more sense.

I'd keep them in their own file for easy access and good organization either way.

I usually wouldn't put them in a class unless they somehow "belong" there. Like you have a Car class with an enum for the types of car, and a Road class and Bridge class that can set limits for types of car. Car.CarType seems to be a logical organization for this...
