C# 让枚举返回字符串

下面的手段是使用给枚举项打标签的方式,来返回字符串

分别定义一个属性类,一个枚举帮助类

 /// <summary>
     /// 自定义属性
     /// </summary>
     [AttributeUsage(AttributeTargets.Field, AllowMultiple = false)]
     public sealed class EnumDescriptionAttribute : Attribute
     {
         private string description;
         public string Description { get { return description; } }

         public EnumDescriptionAttribute(string description)
             : base()
         {
             this.description = description;
         }
     }

     /// <summary>
     /// 获取枚举字符串
     /// </summary>
     public static class EnumHelper
     {
         public static string GetDescription(Enum value)
         {
             if (value == null)
             {
                 throw new ArgumentException("value");
             }
             string description = value.ToString();
             var fieldInfo = value.GetType().GetField(description);
             var attributes =
                 (EnumDescriptionAttribute[])fieldInfo.GetCustomAttributes(typeof(EnumDescriptionAttribute), false);
             if (attributes != null && attributes.Length > )
             {
                 description = attributes[].Description;
             }
             return description;
         }
     }

 enum Week
 {
     [EnumDescription("星期一")]
     Monday,
     [EnumDescription("星期二")]
     Tuesday
 }  

 //下面打印结果为: 星期一
 Console.WriteLine(EnuHelper.GetDescription(Week.Monday))
