创建一个单独称为DeviceInformation的新属性…

 [AttributeUsage(AttributeTargets.All)] public class DeviceInformationAttribute : DescriptionAttribute { public DeviceInformationAttribute(string description, string value) { this.Description = description; this.Value = value; } public string Description { get; set; } public string Value { get; set; } } 

您还可以使用扩展方法来检索任何属性的值

 static void Main(string[] args) { var info = DeviceType.Stb.GetAttribute(); Console.WriteLine("Description: {0}nValue:{1}",info.Description, info.Value); } public static class Extensions { public static TAttribute GetAttribute(this Enum enumValue) where TAttribute : Attribute { return enumValue.GetType() .GetMember(enumValue.ToString()) .First() .GetCustomAttribute(); } } public enum DeviceType { [DeviceInformation("foobar", "100")] Stb = 1, }

@Aydin Adn我喜欢使用扩展方法，非常好！ 您是否有针对DeviceType.Panel案例的解决方案，该解决方案没有描述，但需要Value属性？ （见Patrick的回答评论）

  [AttributeUsage(AttributeTargets.All)] public class DeviceInformationAttribute : Attribute { public DeviceInformationAttribute(string description) { this.Description = description; } public DeviceInformationAttribute(decimal value) { this.Description = string.Empty; this.Value = value; } public DeviceInformationAttribute(string description, decimal value) { this.Description = description; this.Value = value; } public string Description { get; set; } public decimal Value { get; set; } } 

是的，这很容易做到。 只需派生现有的DescriptionAttribute类：

 [AttributeUsageAttribute(AttributeTargets.All)] public class DescriptionWithValueAttribute : DescriptionAttribute { public DescriptionWithValueAttribute(string description, string value) : base(description) { this.Value = value; } public string Value { get; private set; } } 

然后你可以像这样使用它：

 public enum DeviceType { [DescriptionWithValue("Set Top Box", "19.95")] Stb = 1, } 

检索属性的代码将保持几乎相同，只需替换类型名称即可。

你想要做的是：创建一个属性来描述更具体的枚举：这是你如何做到的：

 public class EnumValue : Attribute { public Decimal Value { get; private set; } public EnumValue(Decimal value) { this.Value = value; } } 

这可以通过此扩展方法使用：

 private static Decimal GetEnumCustomAttribute(this Enum leEnum, Typ typ) { try { if (leEnum == null) throw new ArgumentNullException("leEnum"); Type type = leEnum.GetType(); MemberInfo[] memInfo = type.GetMember(leEnum.ToString()); if (memInfo != null && memInfo.Length > 0) { object[] attrs = memInfo[0].GetCustomAttributes(typeof(EnumValue), false); if (attrs != null && attrs.Length > 0) return ((EnumValue)attrs[0]).Value; } return Decimal.MinValue; } catch (Exception) { throw; } } 

试试看！

为什么不在一个class级里做呢。 一开始还有点工作，但是：
