C#enum使用Attribute求字段名

用到了一些反射：（自己看吧）

public enum UserState
    {
        /// <summary>
        /// 正常
        /// </summary>
        [Remark("正常")]
        Normal = 0,//左边是字段名称  右边是数据库值   哪里放描述？  注释
        /// <summary>
        /// 冻结
        /// </summary>
        [Remark("冻结")]
        Frozen = 1,
        /// <summary>
        /// 删除
        /// </summary>
        //[Remark("删除")]
        Deleted = 2
    }
