我不需要任何健壮的东西，比如将字符串存储在属性中。我只需要转动MyEnum之类的东西。BillEveryWeek变成“每周账单”或MyEnum。将elegacysystem转换为“使用遗留系统”——基本上通过驼峰式大小写将枚举拆分为单个小写单词。

public static string UnCamelCase(this Enum input, string delimiter = " ", bool preserveCasing = false)
{
    var characters = input.ToString().Select((x, i) =>
    {

       if (i > 0 && char.IsUpper(x))
       {
           return delimiter + x.ToString(CultureInfo.InvariantCulture);
       }
       return x.ToString(CultureInfo.InvariantCulture);

    });

    var result = preserveCasing
       ? string.Concat(characters)
       : string.Concat(characters).ToLower();

    var lastComma = result.LastIndexOf(", ", StringComparison.Ordinal);

    if (lastComma > -1)
    {
       result = result.Remove(lastComma, 2).Insert(lastComma, " and ");
    }

    return result;
}

myenume . uselegacysystem . uncamelcase()输出"使用遗留系统"

如果设置了多个标志，它会将其转换为普通英语(逗号分隔，除了最后一个逗号中的“and”)。

var myCustomerBehaviour = MyEnum.BillEveryWeek | MyEnum.UseLegacySystem | MyEnum.ChargeTaxes;

Console.WriteLine(myCustomerBehaviour.UnCamelCase());
//outputs "bill every week, use legacy system and charge taxes"

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());

下面是我对这个问题的看法，使用c# 9.0语法来保持整洁。我为枚举定义了一个基类:

public class StringEnum
{
    protected StringEnum(string value) { Value = value; }
    public string Value { get; }
    public override string ToString() => Value;
}

创建新的枚举样式类型是简单而紧凑的:

public class GroupTypes : StringEnum
{ 
    private GroupTypes(string value) : base(value) {}

    public static readonly GroupTypes TheGroup = new("OEM");
    public static readonly GroupTypes TheOtherGroup = new("CMB");
}

像这样使用它:

void Example(GroupTypes groupType)
{
    Console.WriteLine(groupType); // Will print "OEM" or "CMB"
    if (groupType == GroupTypes.TheGroup) { ... }
}

你也可以给StringEnum添加更多的功能，这样你的所有子类都可以使用(例如，实现IComparable和重写Equals和GetHashCode)

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()]);

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");
}

为什么不使用相同的枚举，而只是调用.ToString()?

using System;

public class EnumSample
{
    enum Holidays
    {
        Christmas = 1,
        Easter = 2
    };

    public static void Main()
    {
        Enum myHolidays = Holidays.Christmas;
        Console.WriteLine("The value of this instance is '{0}'", myHolidays.ToString());
    }
}
