Hey I think this would help you, actually your question is not clear but i think you are asking follow:
using System;
using System.Collections.Generic;
using System.Text;
namespace ConsoleApplication3
{
[Flags]
enum month { jan=1,feb=2,mar=4,apr=8,may=16};
class Program
{
static void Main(string[] args)
{
month m = month.jan | month.apr;
Console.WriteLine("months: "+m);
for (int i = 1; i < 16; i++)
{
Console.WriteLine("{0,3}- {1}",i,((month)i).ToString());
}
Console.Read();
}
}
}
