C#遍历枚举(Enum)

 public enum WeekDay
        {
            Sun=0,
            Mon=1,
            Tue=2,
            Wed=3,
            Thu=4,
            Fri=5,
            Sat=6,
        }
        static void Main(string[] args)
        {
            foreach (WeekDay day in Enum.GetValues(typeof(WeekDay)))
            {
                Console.WriteLine((int)day+":"+day);
            }
            Console.ReadKey();
        }

结果如下图:
