利用DescriptionAttribute实现枚举字符串

我们知道定义枚举时是不允许带空格等符号的，这样就不利于进行字符串对比。当然可以通过给枚举添加DescriptionAttribute，然后通过fieldinfo读取DescriptionAttribute来获取字符串。

以下是例子

先定义枚举

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21

/// <summary> /// Campaign Mode /// </summary> public enum CampaignModeEnum {     /// <summary>     /// Inbound     /// </summary>     [DescriptionAttribute("Inbound")]     Inbound,     /// <summary>     /// Outbound Preview     /// </summary>     [DescriptionAttribute("Outbound Preview")]     Outbound_Preview,     /// <summary>     /// Outbound Predictive     /// </summary>     [DescriptionAttribute("Outbound Predictive")]     Outbound_Predictive }

编写获取DescriptionAttribute的类

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

public static class EnumMethod {     public static string StringValue(Enum value)     {         FieldInfo fi = value.GetType().GetField(value.ToString());         DescriptionAttribute[] attributes = (DescriptionAttribute[])fi.GetCustomAttributes(typeof(DescriptionAttribute), false);         if (attributes.Length > 0)         {             return attributes[0].Description;         }         else         {             return value.ToString();         }     } }

　　

这样调用就可以啦！

EnumMethod.StringValue(CampaignModeEnum.Outbound_Predictive);
