Enum Values As Bit Flags
Enumerations can be designed for supporting bitwise operations by marking them with the Flags attribute. This allows combining enumeration values with bitwise operators such as And and Or. Consider the following implementation of the Sports enumeration that was described previously:
<Flags>Public Enum Sports None = 0 Biking = 1 Climbing = 2 Swimming = 4 Running = 8End Enum
When you apply the Flags attribute, enumeration values are treated as a set of bit fields. It is important to define enumeration constants in powers of two (1, 2, 4, 8, and so on) so that individual flags in combined enumeration constants do not overlap.
When you Flags, values are evaluated in binary and can be combined with bitwise operators. ...
