这是一种将它用作强类型参数或字符串的方法:

public class ClassLikeEnum
{
    public string Value
    {
        get;
        private set;
    }

    ClassLikeEnum(string value) 
    {
        Value = value;
    }

    public static implicit operator string(ClassLikeEnum c)
    {
        return c.Value;
    }

    public static readonly ClassLikeEnum C1 = new ClassLikeEnum("RandomString1");
    public static readonly ClassLikeEnum C2 = new ClassLikeEnum("RandomString2");
}

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(); }
}

在VS 2015中，你可以使用nameof

public class LogCategory
{
    public static string Trace;
    public static string Debug;
    public static string Info;
    public static string Warning;
    public static string Error;
}

用法:

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

我会把它变成一个类，完全避免使用枚举。然后使用类型处理程序，你可以在从db中获取对象时创建对象。

即:

public class Group
{
    public string Value{ get; set; }
    public Group( string value ){ Value = value; } 
    public static Group TheGroup() { return new Group("OEM"); }
    public static Group OtherGroup() { return new Group("CMB"); }

}

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。

基于https://stackoverflow.com/a/1343517/1818723，我提出了一个枚举与TryParse方法

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

    public string Value { get; private set; }

    private static List<FancyStringEnum> choices = new List<FancyStringEnum>
    {
        new FancyStringEnum("Small") ,
        new FancyStringEnum("Big Thing") ,
        new FancyStringEnum("Value with Spaces")
    };

    public static FancyStringEnum Small { get { return choices[0]; } }
    public static FancyStringEnum BigThing { get { return choices[1]; } }
    public static FancyStringEnum ValueWithSpaces { get { return choices[2]; } }

    public override string ToString()
    {
        return Value;
    }

    public static bool TryParse(string value, bool ignoreCase, out FancyStringEnum result)
    {
        var sc = StringComparison.InvariantCulture;
        if (ignoreCase)
            sc = StringComparison.InvariantCultureIgnoreCase;

        foreach (var choice in choices)
        {

            if (choice.Value.Equals(value, sc))
            {
                result = choice;
                return true;
            }
        }

        result = new FancyStringEnum(null);
        return false;
    }

    public static FancyStringEnum Parse(string value, bool ignoreCase)
    {
        var sc = StringComparison.InvariantCulture;
        if (ignoreCase)
            sc = StringComparison.InvariantCultureIgnoreCase;

        foreach (var choice in choices)
        {

            if (choice.Value.Equals(value, sc))
            {
                return choice;
            }
        }

        return new FancyStringEnum(null);
    }
}

传入类型安全的字符串值作为参数:

public static void Do(string message, FancyStringEnum value)
{
    if (value == FancyStringEnum.Small)
    {
        //do something
    } else if (value == FancyStringEnum.BigThing)
    {
        //do something else
    }
}

TryParse和Parse在行动:

string something = "something"; //substiture with "small" to see it parsed 
if (FancyStringEnum.TryParse(something, true, out var se))
    Console.WriteLine(se.Value);
else
    Console.WriteLine($"unable to parse {something}");

//or    

var v2 = FancyStringEnum.Parse(something, true);
if (v2.Value == null)
    Console.WriteLine($"unable to parse {something}");
else
    Console.WriteLine(v2.Value); //do something with parsed enum

    

是否可以提取基类，用更少的代码创建StringEnums
