当我遇到这样的情况时，我提出下面的解决方案。

作为一个消费阶级，你可以有

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace MyApp.Dictionaries
{
    class Greek
    {

        public static readonly string Alpha = "Alpha";
        public static readonly string Beta = "Beta";
        public static readonly string Gamma = "Gamma";
        public static readonly string Delta = "Delta";


        private static readonly BiDictionary<int, string> Dictionary = new BiDictionary<int, string>();


        static Greek() {
            Dictionary.Add(1, Alpha);
            Dictionary.Add(2, Beta);
            Dictionary.Add(3, Gamma);
            Dictionary.Add(4, Delta);
        }

        public static string getById(int id){
            return Dictionary.GetByFirst(id);
        }

        public static int getByValue(string value)
        {
            return Dictionary.GetBySecond(value);
        }

    }
}

使用双向字典: 基于此(https://stackoverflow.com/a/255638/986160)，假设键将与字典中的单个值相关联，类似于(https://stackoverflow.com/a/255630/986160)，但更优雅一些。这个字典也是可枚举的，你可以在整型和字符串之间来回切换。此外，除了这个类，你的代码库中不需要有任何字符串。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Collections;

namespace MyApp.Dictionaries
{

    class BiDictionary<TFirst, TSecond> : IEnumerable
    {
        IDictionary<TFirst, TSecond> firstToSecond = new Dictionary<TFirst, TSecond>();
        IDictionary<TSecond, TFirst> secondToFirst = new Dictionary<TSecond, TFirst>();

        public void Add(TFirst first, TSecond second)
        {
            firstToSecond.Add(first, second);
            secondToFirst.Add(second, first);
        }

        public TSecond this[TFirst first]
        {
            get { return GetByFirst(first); }
        }

        public TFirst this[TSecond second]
        {
            get { return GetBySecond(second); }
        }

        public TSecond GetByFirst(TFirst first)
        {
            return firstToSecond[first];
        }

        public TFirst GetBySecond(TSecond second)
        {
            return secondToFirst[second];
        }

        public IEnumerator GetEnumerator()
        {
            return GetFirstEnumerator();
        }

        public IEnumerator GetFirstEnumerator()
        {
            return firstToSecond.GetEnumerator();
        }

        public IEnumerator GetSecondEnumerator()
        {
            return secondToFirst.GetEnumerator();
        }
    }
}

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(); }

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……

好吧，在阅读了以上所有内容后，我觉得这些家伙将枚举数转换为字符串的问题过于复杂了。 我喜欢在枚举字段上拥有属性的想法，但我认为属性主要用于元数据，但在你的情况下，我认为你所需要的只是某种本地化。

public enum Color 
{ Red = 1, Green = 2, Blue = 3}


public static EnumUtils 
{
   public static string GetEnumResourceString(object enumValue)
    {
        Type enumType = enumValue.GetType();
        string value = Enum.GetName(enumValue.GetType(), enumValue);
        string resourceKey = String.Format("{0}_{1}", enumType.Name, value);
        string result = Resources.Enums.ResourceManager.GetString(resourceKey);
        if (string.IsNullOrEmpty(result))
        {
            result = String.Format("{0}", value);
        }
        return result;
    }
}

现在如果我们尝试调用上面的方法，我们可以这样调用它

public void Foo()
{
  var col = Color.Red;
  Console.WriteLine (EnumUtils.GetEnumResourceString (col));
}

您所需要做的就是创建一个包含所有枚举值和相应字符串的资源文件

Resource Name          Resource Value
Color_Red              My String Color in Red
Color_Blue             Blueeey
Color_Green            Hulk Color

这样做的好处是，如果您需要本地化应用程序，它将非常有用，因为您所需要做的只是用新语言创建另一个资源文件!和Voe-la !

使用对象枚举. parse(系统。类型枚举类型，字符串值，bool ignoreCase);从http://blogs.msdn.com/b/tims/archive/2004/04/02/106310.aspx获取

基于MSDN: http://msdn.microsoft.com/en-us/library/cc138362.aspx

foreach (string str in Enum.GetNames(typeof(enumHeaderField)))
{
    Debug.WriteLine(str);
}

STR将是字段的名称
