我使用一个扩展方法:

public static class AttributesHelperExtension
    {
        public static string ToDescription(this Enum value)
        {
            var da = (DescriptionAttribute[])(value.GetType().GetField(value.ToString())).GetCustomAttributes(typeof(DescriptionAttribute), false);
            return da.Length > 0 ? da[0].Description : value.ToString();
        }
}

现在用:

public enum AuthenticationMethod
{
    [Description("FORMS")]
    FORMS = 1,
    [Description("WINDOWSAUTHENTICATION")]
    WINDOWSAUTHENTICATION = 2,
    [Description("SINGLESIGNON ")]
    SINGLESIGNON = 3
}

当你打电话时

AuthenticationMethod.FORMS.ToDescription()将得到“FORMS”。

选项1:

public sealed class FormsAuth
{
     public override string ToString{return "Forms Authtentication";}
}
public sealed class WindowsAuth
{
     public override string ToString{return "Windows Authtentication";}
}

public sealed class SsoAuth
{
     public override string ToString{return "SSO";}
}

然后

object auth = new SsoAuth(); //or whatever

//...
//...
// blablabla

DoSomethingWithTheAuth(auth.ToString());

选项2:

public enum AuthenticationMethod
{
        FORMS = 1,
        WINDOWSAUTHENTICATION = 2,
        SINGLESIGNON = 3
}

public class MyClass
{
    private Dictionary<AuthenticationMethod, String> map = new Dictionary<AuthenticationMethod, String>();
    public MyClass()
    {
         map.Add(AuthenticationMethod.FORMS,"Forms Authentication");
         map.Add(AuthenticationMethod.WINDOWSAUTHENTICATION ,"Windows Authentication");
         map.Add(AuthenticationMethod.SINGLESIGNON ,"SSo Authentication");
    }
}

我发现的Enums国际化或从各自的资源文件获取Enums文本的方法是通过继承DescriptionAttribute类创建一个属性类

public class EnumResourceAttribute : DescriptionAttribute
{

    public Type ResourceType { get; private set; }
    public string ResourceName { get; private set; }
    public int SortOrder { get; private set; }
    public EnumResourceAttribute(Type ResourceType,
                         string ResourceName,
                         int SortOrder)
    {

        this.ResourceType = ResourceType;
        this.ResourceName = ResourceName;
        this.SortOrder = SortOrder;
    }
}

创建另一个Static类，为GetString和GetString提供扩展方法。

public static class EnumHelper
{
    public static string GetString(this Enum value)
    {
        EnumResourceAttribute ea =
       (EnumResourceAttribute)value.GetType().GetField(value.ToString())
        .GetCustomAttributes(typeof(EnumResourceAttribute), false)
         .FirstOrDefault();
        if (ea != null)
        {
            PropertyInfo pi = ea.ResourceType
             .GetProperty(CommonConstants.ResourceManager);
            if (pi != null)
            {
                ResourceManager rm = (ResourceManager)pi
                .GetValue(null, null);
                return rm.GetString(ea.ResourceName);
            }

        }
        return string.Empty;
    }


    public static IList GetStrings(this Type enumType)
    {
        List<string> stringList = new List<string>();
        FieldInfo[] fiArray = enumType.GetFields();
        foreach (FieldInfo fi in fiArray)
        {
            EnumResourceAttribute ea =
                (EnumResourceAttribute)fi
                     .GetCustomAttributes(typeof(EnumResourceAttribute), false)
                     .FirstOrDefault();
            if (ea != null)
            {
                PropertyInfo pi = ea.ResourceType
                                    .GetProperty(CommonConstants.ResourceManager);
                if (pi != null)
                {
                    ResourceManager rm = (ResourceManager)pi
                                          .GetValue(null, null);
                    stringList.Add(rm.GetString(ea.ResourceName));
                }
            }
        }
        return stringList.ToList();
    }
}

在Enum的元素上，你可以这样写:

public enum Priority
{
     [EnumResourceAttribute(typeof(Resources.AdviceModule), Resources.ResourceNames.AdviceCreateAdviceExternaPriorityMemberHigh, 1)]
    High,
     [EnumResourceAttribute(typeof(Resources.AdviceModule), Resources.ResourceNames.AdviceCreateAdviceExternaPriorityMemberRoutine, 2)]
    Routine
}

Where Resources.ResourceNames.AdviceCreateAdviceExternaPriorityMemberHigh & resources . resourcename . advicecreateadviceexternaprioritymemberroutine是资源文件中的常量，或者你可以说字符串，其值可以在不同的文化中可用。

如果你在MVC架构中实现你的web应用程序，那么创建一个属性

private IList result;
public IList Result
{
    get
    {
        result = typeof(Priority).GetStrings();
        return result;
    }
}

在你的.cshtml文件中，你可以像这样将枚举绑定到你的下拉列表:

@Html.DropDownListFor(model => Model.vwClinicalInfo.Priority, new SelectList(Model.Result))

谢谢 Ratnesh

这里有很多很棒的答案，但在我的情况下，并没有解决我想要的“字符串enum”，这是:

可用在switch语句中，例如switch(myEnum) 可以在函数参数中使用，例如foo(myEnum类型) 可以引用，例如myEnum。FirstElement 我可以使用字符串，例如foo("FirstElement") == foo(myenumer .FirstElement)

1、2和4实际上可以用一个字符串的c#类型定义来解决(因为字符串在c#中是可切换的)

3可以通过静态const字符串来求解。所以如果你有同样的需求，这是最简单的方法:

public sealed class Types
{

    private readonly String name;

    private Types(String name)
    {
        this.name = name;

    }

    public override String ToString()
    {
        return name;
    }

    public static implicit operator Types(string str)
    {
        return new Types(str);

    }
    public static implicit operator string(Types str)
    {
        return str.ToString();
    }


    #region enum

    public const string DataType = "Data";
    public const string ImageType = "Image";
    public const string Folder = "Folder";
    #endregion

}

这允许例如:

    public TypeArgs(Types SelectedType)
    {
        Types SelectedType = SelectedType
    }

and

public TypeObject CreateType(Types type)
    {
        switch (type)
        {

            case Types.ImageType:
              //
                break;

            case Types.DataType:
             //
                break;

        }
    }

CreateType可以用字符串或类型调用。然而，缺点是任何字符串都是自动有效的enum，这可以被修改，但它将需要某种init函数…或者可能使它们显式转换内部?

现在，如果一个int值对你来说很重要(也许是比较速度)，你可以使用Jakub Šturc的一些想法，做一些疯狂的事情，这是我的尝试:

    public sealed class Types
{
    private static readonly Dictionary<string, Types> strInstance = new Dictionary<string, Types>();
    private static readonly Dictionary<int, Types> intInstance = new Dictionary<int, Types>();

    private readonly String name;
    private static int layerTypeCount = 0;
    private int value;
    private Types(String name)
    {
        this.name = name;
        value = layerTypeCount++;
        strInstance[name] = this;
        intInstance[value] = this;
    }

    public override String ToString()
    {
        return name;
    }


    public static implicit operator Types(int val)
    {
        Types result;
        if (intInstance.TryGetValue(val, out result))
            return result;
        else
            throw new InvalidCastException();
    }

    public static implicit operator Types(string str)
    {
        Types result;
        if (strInstance.TryGetValue(str, out result))
        {
            return result;
        }
        else
        {
            result = new Types(str);
            return result;
        }

    }
    public static implicit operator string(Types str)
    {
        return str.ToString();
    }

    public static bool operator ==(Types a, Types b)
    {
        return a.value == b.value;
    }
    public static bool operator !=(Types a, Types b)
    {
        return a.value != b.value;
    }

    #region enum

    public const string DataType = "Data";
    public const string ImageType = "Image";

    #endregion

}

但是当然"Types bob = 4;"是没有意义的，除非你先对它们进行初始化，这就有点失败了……

但理论上a型== b型会更快…

试试type-safe-enum模式。

public sealed class AuthenticationMethod {

    private readonly String name;
    private readonly int value;

    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){
        this.name = name;
        this.value = value;
    }

    public override String ToString(){
        return name;
    }

}

更新 显式(或隐式)类型转换可以通过

adding static field with mapping private static readonly Dictionary<string, AuthenticationMethod> instance = new Dictionary<string,AuthenticationMethod>(); n.b. In order that the initialisation of the the "enum member" fields doesn't throw a NullReferenceException when calling the instance constructor, be sure to put the Dictionary field before the "enum member" fields in your class. This is because static field initialisers are called in declaration order, and before the static constructor, creating the weird and necessary but confusing situation that the instance constructor can be called before all static fields have been initialised, and before the static constructor is called. filling this mapping in instance constructor instance[name] = this; and adding user-defined type conversion operator public static explicit operator AuthenticationMethod(string str) { AuthenticationMethod result; if (instance.TryGetValue(str, out result)) return result; else throw new InvalidCastException(); }

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
}
