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。

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(); }

我如何解决这个扩展方法:

using System.ComponentModel;
public static string GetDescription(this Enum value)
{
    var descriptionAttribute = (DescriptionAttribute)value.GetType()
        .GetField(value.ToString())
        .GetCustomAttributes(false)
        .Where(a => a is DescriptionAttribute)
        .FirstOrDefault();

    return descriptionAttribute != null ? descriptionAttribute.Description : value.ToString();
}

枚举:

public enum OrderType
{
    None = 0,
    [Description("New Card")]
    NewCard = 1,
    [Description("Reload")]
    Refill = 2
}

用法(其中o.OrderType是一个与enum同名的属性):

o.OrderType.GetDescription()

这给了我一个字符串的“新卡”或“重载”，而不是实际的enum值NewCard和重新填充。

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 !

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");
    }
}

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……
