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。

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

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(); }

如果我理解正确，你可以简单地使用.ToString()从值中检索enum的名称(假设它已经被转换为enum); 如果你有裸整型(比如从数据库或其他地方)，你可以先将它强制转换为枚举。 下面的两个方法都将获得枚举名称。

AuthenticationMethod myCurrentSetting = AuthenticationMethod.FORMS;
Console.WriteLine(myCurrentSetting); // Prints: FORMS
string name = Enum.GetNames(typeof(AuthenticationMethod))[(int)myCurrentSetting-1];
Console.WriteLine(name); // Prints: FORMS

但是请记住，第二种技术假设您使用的是int型，并且您的索引基于1(而不是基于0)。相比之下，GetNames函数也相当繁重，每次调用它都要生成一个完整的数组。 正如您在第一种技术中看到的，. tostring()实际上是隐式调用的。 这两个问题都已经在答案中提到了，当然，我只是想澄清它们之间的区别。

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……

我想把这篇文章作为下面引用的帖子的评论，但不能，因为我没有足够的代表。代码包含一个错误，我想向试图使用这个解决方案的个人指出这一点:

[TypeConverter typeof (CustomEnumTypeConverter (typeof (MyEnum))) public enum MyEnum ｛ //自定义类型转换器将使用description属性 [描述(“自定义描述”)] ValueWithCustomDescription, //这将完全暴露。 确切的 ｝

应该是

[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
}
