更新:访问这个页面，8年后，在很长一段时间没有接触c#之后，看起来我的答案不再是最好的解决方案。我非常喜欢与属性-函数绑定的转换器解决方案。

如果你正在阅读这篇文章，请确保你也查看了其他答案。(提示:它们在这个上面)

和你们大多数人一样，我非常喜欢Jakub Šturc所选的答案，但我也非常讨厌复制粘贴代码，并尽可能少地这样做。

因此，我决定使用一个EnumBase类，从其中继承/内置大部分功能，从而使我能够专注于内容而不是行为。

这种方法的主要问题是基于这样一个事实，即尽管Enum值是类型安全的实例，但交互是与Enum Class类型的静态实现进行的。 所以在泛型魔法的帮助下，我想我终于得到了正确的组合。 希望有人能像我一样觉得这个有用。

我将从Jakub的例子开始，但是使用继承和泛型:

public sealed class AuthenticationMethod : EnumBase<AuthenticationMethod, int>
{
    public static readonly AuthenticationMethod FORMS =
        new AuthenticationMethod(1, "FORMS");
    public static readonly AuthenticationMethod WINDOWSAUTHENTICATION =
        new AuthenticationMethod(2, "WINDOWS");
    public static readonly AuthenticationMethod SINGLESIGNON =
        new AuthenticationMethod(3, "SSN");

    private AuthenticationMethod(int Value, String Name)
        : base( Value, Name ) { }
    public new static IEnumerable<AuthenticationMethod> All
    { get { return EnumBase<AuthenticationMethod, int>.All; } }
    public static explicit operator AuthenticationMethod(string str)
    { return Parse(str); }
}

这里是基类:

using System;
using System.Collections.Generic;
using System.Linq; // for the .AsEnumerable() method call

// E is the derived type-safe-enum class
// - this allows all static members to be truly unique to the specific
//   derived class
public class EnumBase<E, T> where E: EnumBase<E, T>
{
    #region Instance code
    public T Value { get; private set; }
    public string Name { get; private set; }

    protected EnumBase(T EnumValue, string Name)
    {
        Value = EnumValue;
        this.Name = Name;
        mapping.Add(Name, this);
    }

    public override string ToString() { return Name; }
    #endregion

    #region Static tools
    static private readonly Dictionary<string, EnumBase<E, T>> mapping;
    static EnumBase() { mapping = new Dictionary<string, EnumBase<E, T>>(); }
    protected static E Parse(string name)
    {
        EnumBase<E, T> result;
        if (mapping.TryGetValue(name, out result))
        {
            return (E)result;
        }

        throw new InvalidCastException();
    }
    // This is protected to force the child class to expose it's own static
    // method.
    // By recreating this static method at the derived class, static
    // initialization will be explicit, promising the mapping dictionary
    // will never be empty when this method is called.
    protected static IEnumerable<E> All
    { get { return mapping.Values.AsEnumerable().Cast<E>(); } }
    #endregion
}

我支持Harvey，但不用const。我可以混合匹配字符串，int，等等。

public class xlsLayout
{
    public int xlHeaderRow = 1;
    public int xlFirstDataRow = 2;
    public int xlSkipLinesBetweenFiles = 1; //so 0 would mean don't skip
    public string xlFileColumn = "A";
    public string xlFieldColumn = "B";
    public string xlFreindlyNameColumn = "C";
    public string xlHelpTextColumn = "D";
}

然后……

public partial class Form1 : Form
{
    xlsLayout xlLayout = new xlsLayout();

    xl.SetCell(xlLayout.xlFileColumn, xlLayout.xlHeaderRow, "File Name");
    xl.SetCell(xlLayout.xlFieldColumn, xlLayout.xlHeaderRow, "Code field name");
    xl.SetCell(xlLayout.xlFreindlyNameColumn, xlLayout.xlHeaderRow, "Freindly name");
    xl.SetCell(xlLayout.xlHelpTextColumn, xlLayout.xlHeaderRow, "Inline Help Text");
}

使用方法

Enum.GetName(Type MyEnumType,  object enumvariable)  

如(假设Shipper是一个已定义的Enum)

Shipper x = Shipper.FederalExpress;
string s = Enum.GetName(typeof(Shipper), x);

Enum类上还有很多其他的静态方法也值得研究……

我使用了上述几个建议的组合，并结合了一些缓存。现在，我从网上找到的一些代码中得到了这个想法，但我既不记得是从哪里得到的，也不记得是怎么找到的。所以如果有人发现了一些相似的东西，请在归因处发表评论。

无论如何，使用涉及到类型转换器，所以如果你绑定到UI，它'只是工作'。您可以使用Jakub的模式进行扩展，通过从类型转换器初始化到静态方法来实现快速代码查找。

基本使用量是这样的

[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
}

自定义枚举类型转换器的代码如下:

public class CustomEnumTypeConverter<T> : EnumConverter
    where T : struct
{
    private static readonly Dictionary<T,string> s_toString = 
      new Dictionary<T, string>();

    private static readonly Dictionary<string, T> s_toValue = 
      new Dictionary<string, T>();

    private static bool s_isInitialized;

    static CustomEnumTypeConverter()
    {
        System.Diagnostics.Debug.Assert(typeof(T).IsEnum,
          "The custom enum class must be used with an enum type.");
    }

    public CustomEnumTypeConverter() : base(typeof(T))
    {
        if (!s_isInitialized)
        {
            Initialize();
            s_isInitialized = true;
        }
    }

    protected void Initialize()
    {
        foreach (T item in Enum.GetValues(typeof(T)))
        {
            string description = GetDescription(item);
            s_toString[item] = description;
            s_toValue[description] = item;
        }
    }

    private static string GetDescription(T optionValue)
    {
        var optionDescription = optionValue.ToString();
        var optionInfo = typeof(T).GetField(optionDescription);
        if (Attribute.IsDefined(optionInfo, typeof(DescriptionAttribute)))
        {
            var attribute = 
              (DescriptionAttribute)Attribute.
                 GetCustomAttribute(optionInfo, typeof(DescriptionAttribute));
            return attribute.Description;
        }
        return optionDescription;
    }

    public override object ConvertTo(ITypeDescriptorContext context, 
       System.Globalization.CultureInfo culture, 
       object value, Type destinationType)
    {
        var optionValue = (T)value;

        if (destinationType == typeof(string) && 
            s_toString.ContainsKey(optionValue))
        {
            return s_toString[optionValue];
        }

        return base.ConvertTo(context, culture, value, destinationType);
    }

    public override object ConvertFrom(ITypeDescriptorContext context, 
       System.Globalization.CultureInfo culture, object value)
    {
        var stringValue = value as string;

        if (!string.IsNullOrEmpty(stringValue) && s_toValue.ContainsKey(stringValue))
        {
            return s_toValue[stringValue];
        }

        return base.ConvertFrom(context, culture, value);
    }
}

}

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。
