摘自@EvenMien，并添加了一些评论。(也适用于我自己的用例)

public struct AgentAction
{
    private AgentAction(string value) { Value = value; }

    public string Value { get; private set; }

    public override string ToString() { return this.Value; }
    
    public static AgentAction Login = new AgentAction("Login");
    public static AgentAction Logout = new AgentAction("Logout");

    public static implicit operator string(AgentAction action) { return action.ToString(); }
}

可以向枚举中的项添加属性，然后使用反射从属性中获取值。

你必须使用"field"说明符来应用属性，如下所示:

enum GroupTypes
{
    [field:Description("OEM")]
    TheGroup,

    [field:Description("CMB")]
    TheOtherGroup
}

然后你将反射枚举类型的静态字段(在本例中是GroupTypes)，并使用反射获取你正在寻找的值的DescriptionAttribute:

public static DescriptionAttribute GetEnumDescriptionAttribute<T>(
    this T value) where T : struct
{
    // The type of the enum, it will be reused.
    Type type = typeof(T);

    // If T is not an enum, get out.
    if (!type.IsEnum) 
        throw new InvalidOperationException(
            "The type parameter T must be an enum type.");

    // If the value isn't defined throw an exception.
    if (!Enum.IsDefined(type, value))
        throw new InvalidEnumArgumentException(
            "value", Convert.ToInt32(value), type);

    // Get the static field for the value.
    FieldInfo fi = type.GetField(value.ToString(), 
        BindingFlags.Static | BindingFlags.Public);

    // Get the description attribute, if there is one.
    return fi.GetCustomAttributes(typeof(DescriptionAttribute), true).
        Cast<DescriptionAttribute>().SingleOrDefault();
}

我选择在上面返回DescriptionAttribute本身，以便您能够确定是否应用了该属性。

c#不支持枚举字符串，但在大多数情况下，您可以使用List或Dictionary来获得所需的效果。

打印通过/失败结果:

List<string> PassFail = new List<string> { "FAIL", "PASS" };
bool result = true;
Console.WriteLine("Test1: " + PassFail[result.GetHashCode()]);

我甚至按照@Even(通过类X和公共静态X成员)的建议实现了一些枚举，只是为了后来发现，从。net 4.5开始，有了正确的ToString()方法。

现在我将所有内容重新实现为枚举。

根据其他人的意见，这是我想到的。这种方法避免了在想要获得常量值的地方键入. value。

我有一个基类的所有字符串枚举像这样:

using System;
using Newtonsoft.Json;

[JsonConverter(typeof(ConstantConverter))]
public class StringEnum: IConvertible
{
    public string Value { get; set; }

    protected StringEnum(string value)
    {
        Value = value;
    }

    public static implicit operator string(StringEnum c)
    {
        return c.Value;
    }
    public string ToString(IFormatProvider provider)
    {
        return Value;
    }

    public TypeCode GetTypeCode()
    {
        throw new NotImplementedException();
    }

    public bool ToBoolean(IFormatProvider provider)
    {
        throw new NotImplementedException();
    }
    //The same for all the rest of IConvertible methods
}

JsonConverter是这样的:

using System;
using Newtonsoft.Json;

class ConstantConverter : JsonConverter
{
    public override bool CanConvert(Type objectType)
    {
        return true;
    }

    public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer)
    {
        throw new NotImplementedException();
    }

    public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer)
    {
        if (value == null)
        {
            serializer.Serialize(writer, null);
        }
        else
        {
            serializer.Serialize(writer, value.ToString());
        }
    }
}

一个实际的string enum是这样的:

public sealed class Colors : StringEnum
{
    public static Colors Red { get { return new Catalog("Red"); } }
    public static Colors Yellow { get { return new Catalog("Yellow"); } }
    public static Colors White { get { return new Catalog("White"); } }

    private Colors(string value) : base(value) { }
}

有了这个，你可以使用颜色。红色甚至序列化到json而不使用Value属性

使用类。

编辑:更好的例子

class StarshipType
{
    private string _Name;
    private static List<StarshipType> _StarshipTypes = new List<StarshipType>();

    public static readonly StarshipType Ultralight = new StarshipType("Ultralight");
    public static readonly StarshipType Light = new StarshipType("Light");
    public static readonly StarshipType Mediumweight = new StarshipType("Mediumweight");
    public static readonly StarshipType Heavy = new StarshipType("Heavy");
    public static readonly StarshipType Superheavy = new StarshipType("Superheavy");

    public string Name
    {
        get { return _Name; }
        private set { _Name = value; }
    }

    public static IList<StarshipType> StarshipTypes
    {
        get { return _StarshipTypes; }
    }

    private StarshipType(string name, int systemRatio)
    {
        Name = name;
        _StarshipTypes.Add(this);
    }

    public static StarshipType Parse(string toParse)
    {
        foreach (StarshipType s in StarshipTypes)
        {
            if (toParse == s.Name)
                return s;
        }
        throw new FormatException("Could not parse string.");
    }
}
