Enum Flags

The following code demostrates how to use enum type in c# as flags.

        [Flags]

        public enum  test

        {

            none = 0,

            a = 0x01,

            b = 0x02,

             c = 0x04,

            d = 0x08

        }

        static  void Main(string[] args)

        {

            test t =  test.none;

            Console.WriteLine(t);

            t = t |  test.a; //set bit a

            Console.WriteLine(t);

             if (t == test.a) 

                Console.WriteLine( "only bit a is set");

            t = t | test.b;  // set bit a

            Console.WriteLine(t);

             if ((t & test.a) != 0) //test to see if bit a is set

                 Console.WriteLine(" test bit a is set");

            Console .ReadKey();

        }

The implementation I was using is to use the BitArray which is very efficient. The good news is I implemented by using code generation which means I only need to modify the code generation templates and all my generated code will be benefiting. :)
