C# 讓枚舉返回字符串

下面的手段是使用給枚舉項打標簽的方式,來返回字符串

分別定義一個屬性類,一個枚舉幫助類

 

/// <summary>
    /// 自定義屬性
    /// </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>
    /// 獲取枚舉字符串
    /// </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 > 0)
            {
                description = attributes[0].Description;
            }
            return description;
        }
    }

 

 

enum Week  
{  
    [EnumDescription("星期一")]  
    Monday,  
    [EnumDescription("星期二")]  
    Tuesday  
}  
  
//下面打印結果為: 星期一  
Console.WriteLine(EnuHelper.GetDescription(Week.Monday))
