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) ==         


        

Answer 1

or... public static bool IsSet(this Enum value, Enum compare) { int baseValue = value.ToInt32(); int compareValue = compare.ToInt32(); if (baseValue == 0) return false; return ((baseValue & compareValue) == compareValue); }
