定义：

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading.Tasks;namespace pub.Enums{    [Flags]    public enum oriention    {        north = 1,        south = 2,        east = 4,        west = 8    }}

后台代码：

oriention aa = oriention.north| oriention.east| oriention.west;            Response.Write((oriention.north | oriention.east | oriention.west)+":" +Convert.ToInt32(aa) + "<br>");            if ((int)(aa & oriention.east)!=0)            {                Response.Write(oriention.east + "包含在aa里面<br>");            }            if ((int)(aa & oriention.south) != 0)            {                Response.Write(oriention.south + "包含在aa里面<br>");            }            Response.Write("3代表："+(oriention)3+"<br>");            Response.Write("aa & oriention.east：" + (aa & oriention.east) + "<br>");            Response.Write("aa & oriention.south：" + (aa & oriention.south) + "<br>");            Response.Write("aa & oriention.east：" + (int)(aa & oriention.east) + "<br>");            Response.Write("aa & oriention.south：" + (int)(aa & oriention.south) + "<br>");

前台输出：

north, east, west:13
east包含在aa里面
3代表：north, south
aa & oriention.east：east
aa & oriention.south：0
aa & oriention.east：4
aa & oriention.south：0
