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

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(); }

可以使用ToString()引用名称而不是值

Console.WriteLine("Auth method: {0}", AuthenticationMethod.Forms.ToString());

.．.如果你在Pascal情况下命名你的枚举(如ThisIsMyEnumValue = 1等)，那么你可以使用一个非常简单的正则表达式来打印友好的形式:

static string ToFriendlyCase(this string EnumString)
{
    return Regex.Replace(EnumString, "(?!^)([A-Z])", " $1");
}

可以很容易地从任何字符串调用:

Console.WriteLine("ConvertMyCrazyPascalCaseSentenceToFriendlyCase".ToFriendlyCase());

输出:

把我疯狂的帕斯卡格句转换成友好格句

这节省了在房子周围运行创建自定义属性并将它们附加到枚举或使用查找表将枚举值与友好字符串结合，最好的是它是自我管理的，可以用于任何Pascal Case字符串，这是无限可重用的。当然，它不允许您使用与解决方案提供的枚举不同的友好名称。

不过，我确实喜欢你针对更复杂场景的原始解决方案。你可以把你的解决方案更进一步，让你的GetStringValue成为你的枚举的扩展方法，然后你就不需要像StringEnum.GetStringValue…

public static string GetStringValue(this AuthenticationMethod value)
{
  string output = null;
  Type type = value.GetType();
  FieldInfo fi = type.GetField(value.ToString());
  StringValue[] attrs = fi.GetCustomAttributes(typeof(StringValue), false) as StringValue[];
  if (attrs.Length > 0)
    output = attrs[0].Value;
  return output;
}

然后你可以直接从你的枚举实例中访问它:

Console.WriteLine(AuthenticationMethod.SSO.GetStringValue());

老帖子，但是…

这个问题的答案其实很简单。使用enumel . tostring()函数

这个函数有6个重载，你可以使用enumenumtostring ("F")或enumenumtostring()来返回字符串值。没必要为其他事操心。这是一个正在运行的演示

注意，这个解决方案可能不适用于所有编译器(这个演示没有像预期的那样工作)，但至少它适用于最新的编译器。

对我来说，实用的方法是类中类，sample:

public class MSEModel
{
    class WITS
    {
        public const string DATE = "5005";
        public const string TIME = "5006";
        public const string MD = "5008";
        public const string ROP = "5075";
        public const string WOB = "5073";
        public const string RPM = "7001";
... 
    }

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);
    }
}

}
