How do you pass multiple enum values in C#?

Question

Sometimes when reading others\' C# code I see a method that will accept multiple enum values in a single parameter. I always thought it was kind of neat, but never looked in

Answer 1

With the help of the posted answers and these:

1. FlagsAttribute Class (Look at the comparison of using and not using the [Flags] attribute)
2. Enum Flags Attribute

I feel like I understand it pretty well.

Thanks.
