首先定义一个扩展属性的类

/// <summary>
        /// 自定义类的信息
        /// </summary>
        [AttributeUsage(AttributeTargets.All, AllowMultiple = true)]
        public class ExtendsAttribute:Attribute
        {
            /// <summary>
            /// 描述性信息
            /// </summary>
            public String Description { get; set; }
            /// <summary>
            /// 静态的值
            /// </summary>
            public int Key { get; set; }
            public ExtendsAttribute(string description)
            {
                Description = description;
            }
            public ExtendsAttribute(int key,string description)
            {
                Key = key;
                Description = description;
            }
        }

然后在枚举类中加入属性类

public  enum VirtualOrderStatus
        {
            /// <summary>
            /// 待付款
            /// </summary>
            [ExtendsAttribute(0, "待付款")]
            WaitPayment = 0,
            /// <summary>
            /// 已付款
            /// </summary>
            [ExtendsAttribute(1, "已付款")]
            Paid = 1,
            /// <summary>
            /// 已发货
            /// </summary>
            [ExtendsAttribute(2, "已发货")]
            SendGoods = 2,
            /// <summary>
            /// 已收货
            /// </summary>
            [ExtendsAttribute(3, "已收货")]
            Deliveries = 3,
            /// <summary>
            /// 已完成
            /// </summary>
            [ExtendsAttribute(4, "已完成")]
            Finished = 4,
            /// <summary>
            ///已取消
            /// </summary>
            [ExtendsAttribute(5, "已取消")]
            Canceled = 5
        }

获取枚举的中文值

/// <summary>
            /// 获取虚拟订单状态
            /// </summary>
            /// <returns></returns>
            public static Dictionary<int, string> GetVirtualOrderStatus()
            {
                Dictionary<int, string> state = new Dictionary<int, string>();
                Type orderStatus = typeof(Common.Enum.VirtualOrderStatus);
                string[] name = orderStatus.GetEnumNames();
                for (int i = 0; i < name.Length; i++)
                {
                    System.Reflection.FieldInfo field = orderStatus.GetField(name[i]);
                    Common.ExtendsAttribute extendAtrr = field.GetCustomAttributes(typeof(Common.ExtendsAttribute), false)[0] as Common.ExtendsAttribute;
                    state.Add(extendAtrr.Key, extendAtrr.Description);
                }
                if (state.Count > 0)
                {
                    return state;
                }
                return null;
            }
