Enum.HasFlag, why no Enum.SetFlag?

Question

I have to build an extension method for each flag type I declare, like so:

public static EventMessageScope SetFlag(this EventMessageScope flags, 
    EventMe

To answer part of your your question: the Get function works properly according to binary logic - it checks for any match. If you want to match the whole set of flags, consider this instead:

return ((flags & flag) != flag);

Regarding "why isn't there SetFlag"... probably because it's not really needed. Flags are integers. There is already a convention for dealing with those and it applies to flags as well. If you don't want to write it with | and & - that's what the custom static addons are for - you can just use your own functions as you demonstrated yourself :)
