C#枚举的应用 

public enum week
   {
       monday = 1,
       tuesday,
       wednesday,
       thursday,
       friday,
       saturday,
       sunday
   }
       static void Main(string[] args)
   {
       Console.WriteLine((int)week.monday);
       Console.WriteLine((int)week.tuesday);
       Console.WriteLine((int)week.wednesday);
       Console.WriteLine((int)week.thursday);
       Console.WriteLine((int)week.friday);
       Console.WriteLine((int)week.saturday);
       Console.WriteLine((int)week.sunday);   
       //以上代码编译出的结果为 1 2 3 4 5 6 7
       //不加转换结果为 monday tuesday wednesday thursday friday saturday sunday     
       testEnum();
       //以上方法 枚举值进行比较  可通过转换进行比较。 数据类型可转枚举 枚举也可转数据类型
   }   
   /// <summary>
   /// 判断枚举
   /// </summary>
   private static void testEnum()
   {
       bool test = (int)week.monday == 1 ? true : false;
       Console.WriteLine(test);
   }
