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(); }
}

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.");
    }
}

你也可以使用扩展模型:

public enum MyEnum
{
    [Description("String 1")]
    V1= 1,
    [Description("String 2")]
    V2= 2
} 

你的扩展类

public static class MyEnumExtensions
{
    public static string ToDescriptionString(this MyEnum val)
    {
        DescriptionAttribute[] attributes = (DescriptionAttribute[])val
           .GetType()
           .GetField(val.ToString())
           .GetCustomAttributes(typeof(DescriptionAttribute), false);
        return attributes.Length > 0 ? attributes[0].Description : string.Empty;
    }
} 

用法:

MyEnum myLocal = MyEnum.V1;
print(myLocal.ToDescriptionString());

我喜欢在类中使用属性而不是方法，因为它们看起来更像枚举。

下面是一个Logger的例子:

public class LogCategory
{
    private LogCategory(string value) { Value = value; }

    public string Value { get; private set; }

    public static LogCategory Trace   { get { return new LogCategory("Trace"); } }
    public static LogCategory Debug   { get { return new LogCategory("Debug"); } }
    public static LogCategory Info    { get { return new LogCategory("Info"); } }
    public static LogCategory Warning { get { return new LogCategory("Warning"); } }
    public static LogCategory Error   { get { return new LogCategory("Error"); } }

    public override string ToString()
    {
        return Value;
    }
}

传入类型安全的字符串值作为参数:

public static void Write(string message, LogCategory logCategory)
{
    var log = new LogEntry { Message = message };
    Logger.Write(log, logCategory.Value);
}

用法:

Logger.Write("This is almost like an enum.", LogCategory.Info);

尝试向静态类中添加常量。你最终不会得到一个Type，但你会得到可读的、有组织的常量:

public static class GroupTypes {

    public const string TheGroup = "OEM";
    public const string TheOtherGroup = "CMB";

}

. net Core 3.0/ c# 8.0(如果你的工作环境允许你升级你的项目)新增了一个简短的switch语句，看起来有点枚举。在一天结束的时候，这和我们多年来一直在使用的无聊的开关语句是一样的。

这里唯一真正的区别是switch语句得到了一个新的suit。

public static RGBColor FromRainbow(Rainbow colorBand) =>
colorBand switch
{
    Rainbow.Red    => new RGBColor(0xFF, 0x00, 0x00),
    Rainbow.Orange => new RGBColor(0xFF, 0x7F, 0x00),
    Rainbow.Yellow => new RGBColor(0xFF, 0xFF, 0x00),
    Rainbow.Green  => new RGBColor(0x00, 0xFF, 0x00),
    Rainbow.Blue   => new RGBColor(0x00, 0x00, 0xFF),
    Rainbow.Indigo => new RGBColor(0x4B, 0x00, 0x82),
    Rainbow.Violet => new RGBColor(0x94, 0x00, 0xD3),
    _              => throw new ArgumentException(message: "invalid enum value", paramName: nameof(colorBand)),
};

你会注意到上面我从这里复制的代码，实际上是使用一个枚举作为参数。

这并不是您想要的(相信我，我早就想要类似OP要求的东西了)，但我实际上觉得这是MS. JMO抛出的橄榄枝。

希望它能帮助到一些人!
