Comparing enum flags in C#

Question

I need to detect if a flag is set within an enum value, which type is marked with the Flag attribute.

Usually it is made like that:

(value & flag) ==

Personally, I think that look fine because you've wrapped it into a single purpose function. If you had that code scattered through an entire program I think you would have some problems, but what you've created improves clarity everywhere it is used and the function itself is clear enough what it does.

Just my opinion of course.

You could though, use the is keyword, which might help a little

public static bool IsSet(this T value, T flags) where T : Enum
{ 
    if (value is int)
    {
        return ((int)(object)a & (int)(object)b) == (int)(object)b);
    }
    //etc...
