Something you probably don't know about enums in C# (blog.spontaneouspublicity.com)

published 2 years ago, submitted by HoolieManHoolieMan(1680) 2 years ago

Do you think the use of an enum in your code is limiting the possible values that can be used? Think again. Maybe we need to learn to be more careful about checking our enums for valid values.

I'm 99% sure its this way so that you can logical-OR together enum values and store the result with a variable of the enum's type.

Yeah, the logical-OR scenario seems like the best explanation. It would be nice if they limited this behavior only to enums with the [Flags] attribute just to make things clearer for enums which are not meant to be OR'd together.

Interesting. I smell an FxCop rule coming.

I was googling a bit. Do you know the 'FlagsAttribute' that you can put on top of an enum defenition?
