我想把这篇文章作为下面引用的帖子的评论，但不能，因为我没有足够的代表。代码包含一个错误，我想向试图使用这个解决方案的个人指出这一点:

[TypeConverter typeof (CustomEnumTypeConverter (typeof (MyEnum))) public enum MyEnum ｛ //自定义类型转换器将使用description属性 [描述(“自定义描述”)] ValueWithCustomDescription, //这将完全暴露。 确切的 ｝

应该是

[TypeConverter(typeof(CustomEnumTypeConverter<MyEnum>))]
public enum MyEnum
{
  // The custom type converter will use the description attribute
  [Description("A custom description")]
  ValueWithCustomDescription,

  // This will be exposed exactly.
  Exact
}

我很清楚这个问题已经被回答了，而且OP已经对接受的答案感到满意。但我发现大多数答案，包括公认的答案，都有点复杂。

我有一个项目给了我这样的情况，我能够以这种方式实现它。

首先，你必须考虑枚举名称的大小写:

public enum AuthenticationMethod
{
    Forms = 1,
    WindowsAuthentication = 2,
    SingleSignOn = 3
}

然后，有这个扩展:

using System.Text.RegularExpression;

public static class AnExtension
{
    public static string Name(this Enum value)
    {
        string strVal = value.ToString();
        try
        {
            return Regex.Replace(strVal, "([a-z])([A-Z])", "$1 $2");
        }
        catch
        {
        }
        return strVal;
    }
}

通过这种方法，您可以将每个枚举名称转换为字符串表示形式，每个单词用空格分隔。例:

AuthenticationMethod am = AuthenticationMethod.WindowsAuthentication;
MessageBox.Show(am.Name());

我创建了一个基类，用于在. net中创建字符串值的枚举。它只是一个c#文件，你可以复制粘贴到你的项目中，或者通过名为StringEnum的NuGet包安装。GitHub回购

如果类被注释为xml comment <completitionlist>，智能感知将提示枚举名称。(适用于c#和VB)

类似于普通enum的用法:

///<completionlist cref="HexColor"/> 
class HexColor : StringEnum<HexColor>
{
    public static readonly HexColor Blue = Create("#FF0000");
    public static readonly HexColor Green = Create("#00FF00");
    public static readonly HexColor Red = Create("#000FF");
}

    // Static Parse Method
    HexColor.Parse("#FF0000") // => HexColor.Red
    HexColor.Parse("#ff0000", caseSensitive: false) // => HexColor.Red
    HexColor.Parse("invalid") // => throws InvalidOperationException

    // Static TryParse method.
    HexColor.TryParse("#FF0000") // => HexColor.Red
    HexColor.TryParse("#ff0000", caseSensitive: false) // => HexColor.Red
    HexColor.TryParse("invalid") // => null

    // Parse and TryParse returns the preexistent instances
    object.ReferenceEquals(HexColor.Parse("#FF0000"), HexColor.Red) // => true

    // Conversion from your `StringEnum` to `string`
    string myString1 = HexColor.Red.ToString(); // => "#FF0000"
    string myString2 = HexColor.Red; // => "#FF0000" (implicit cast)

Instalation:

将下面的StringEnum基类粘贴到项目中。(最新版本) 或者安装StringEnum NuGet包，它基于。net Standard 1.0，所以它可以运行在。net Core >= 1.0， . net Framework >= 4.5, Mono >= 4.6等等。

            }
        }
    }

我使用系统中的Description属性。ComponentModel名称空间。简单地装饰枚举，然后使用下面的代码来检索它:

public static string GetDescription<T>(this object enumerationValue)
            where T : struct
        {
            Type type = enumerationValue.GetType();
            if (!type.IsEnum)
            {
                throw new ArgumentException("EnumerationValue must be of Enum type", "enumerationValue");
            }

            //Tries to find a DescriptionAttribute for a potential friendly name
            //for the enum
            MemberInfo[] memberInfo = type.GetMember(enumerationValue.ToString());
            if (memberInfo != null && memberInfo.Length > 0)
            {
                object[] attrs = memberInfo[0].GetCustomAttributes(typeof(DescriptionAttribute), false);

                if (attrs != null && attrs.Length > 0)
                {
                    //Pull out the description value
                    return ((DescriptionAttribute)attrs[0]).Description;
                }
            }
            //If we have no description attribute, just return the ToString of the enum
            return enumerationValue.ToString();

        }

举个例子:

public enum Cycle : int
{        
   [Description("Daily Cycle")]
   Daily = 1,
   Weekly,
   Monthly
}

这段代码很好地满足了不需要“友好名称”的枚举，只返回枚举的. tostring()。

当我遇到这样的问题时，我首先会试图找到以下几个问题的答案:

枚举值的名称是否足够友好，或者我需要提供更友好的名称? 我需要往返吗?也就是说，我是否需要将文本值解析为枚举值? 这是我需要为我的项目中的许多枚举做的事情，还是只有一个? 我将在什么样的UI元素中呈现这些信息-特别是，我将绑定到UI，还是使用属性表? 这需要本地化吗?

最简单的方法是使用Enum。GetValue(并使用枚举. parse支持往返)。正如Steve Mitcham所建议的那样，构建一个TypeConverter来支持UI绑定通常也是值得的。(在使用属性表时，没有必要构建TypeConverter，这是属性表的优点之一。尽管天晓得他们也有自己的问题。)

一般来说，如果上述问题的答案表明这是行不通的，我的下一步是创建和填充一个静态Dictionary<MyEnum，字符串>，或者可能是一个Dictionary<Type, Dictionary<int，字符串>>。我倾向于跳过中间的用属性装饰代码的步骤，因为接下来通常需要在部署后更改友好值(通常，但不总是，因为本地化)。

我的变体

public struct Colors
{
    private String current;

    private static string red = "#ff0000";
    private static string green = "#00ff00";
    private static string blue = "#0000ff";

    private static IList<String> possibleColors; 

    public static Colors Red { get { return (Colors) red; } }
    public static Colors Green { get { return (Colors) green; } }
    public static Colors Blue { get { return (Colors) blue; } }

    static Colors()
    {
        possibleColors = new List<string>() {red, green, blue};
    }

    public static explicit operator String(Colors value)
    {
        return value.current;
    }

    public static explicit operator Colors(String value)
    {
        if (!possibleColors.Contains(value))
        {
            throw new InvalidCastException();
        }

        Colors color = new Colors();
        color.current = value;
        return color;
    }

    public static bool operator ==(Colors left, Colors right)
    {
        return left.current == right.current;
    }

    public static bool operator !=(Colors left, Colors right)
    {
        return left.current != right.current;
    }

    public bool Equals(Colors other)
    {
        return Equals(other.current, current);
    }

    public override bool Equals(object obj)
    {
        if (ReferenceEquals(null, obj)) return false;
        if (obj.GetType() != typeof(Colors)) return false;
        return Equals((Colors)obj);
    }

    public override int GetHashCode()
    {
        return (current != null ? current.GetHashCode() : 0);
    }

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

代码看起来有点丑，但是这个结构体的用法很有代表性。

Colors color1 = Colors.Red;
Console.WriteLine(color1); // #ff0000

Colors color2 = (Colors) "#00ff00";
Console.WriteLine(color2); // #00ff00

// Colors color3 = "#0000ff"; // Compilation error
// String color4 = Colors.Red; // Compilation error

Colors color5 = (Colors)"#ff0000";
Console.WriteLine(color1 == color5); // True

Colors color6 = (Colors)"#00ff00";
Console.WriteLine(color1 == color6); // False

此外，我认为，如果需要大量这样的枚举，可能会使用代码生成(例如T4)。
