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

    /// <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

    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);
