以上建议的干净总结与样本:

namespace EnumExtensions {

using System;
using System.Reflection;

public class TextAttribute : Attribute {
   public string Text;
   public TextAttribute( string text ) {
      Text = text;
   }//ctor
}// class TextAttribute

public static class EnumExtender {

public static string ToText( this Enum enumeration ) {

   MemberInfo[] memberInfo = enumeration.GetType().GetMember( enumeration.ToString() );

   if ( memberInfo != null && memberInfo.Length > 0 ) {

      object[] attributes = memberInfo[ 0 ].GetCustomAttributes( typeof(TextAttribute),  false );

      if ( attributes != null && attributes.Length > 0 ) {
         return ( (TextAttribute)attributes[ 0 ] ).Text;
      }

   }//if

   return enumeration.ToString();

}//ToText

}//class EnumExtender

}//namespace

用法:

using System;
using EnumExtensions;

class Program {

public enum Appearance {

  [Text( "left-handed" ) ]
  Left,

  [Text( "right-handed" ) ]
  Right,

}//enum

static void Main( string[] args ) {

   var appearance = Appearance.Left;
   Console.WriteLine( appearance.ToText() );

}//Main

}//class

关于Ray Booysen，在代码中有一个错误:Enum ToString与用户友好的字符串

您需要考虑枚举值上的多个属性。

public static string GetDescription<T>(this object enumerationValue)
            where T : struct
    {
        Type type = enumerationValue.GetType();
        if (!type.IsEnum)
        {
            throw new ArgumentException("EnumerationValue must be of Enum type", "enumerationValue");
        }

        //Tries to find a DescriptionAttribute for a potential friendly name
        //for the enum
        MemberInfo[] memberInfo = type.GetMember(enumerationValue.ToString());
        if (memberInfo != null && memberInfo.Length > 0)
        {
            object[] attrs = memberInfo[0].GetCustomAttributes(typeof(DescriptionAttribute), false);

            if (attrs != null && attrs.Length > 0 && attrs.Where(t => t.GetType() == typeof(DescriptionAttribute)).FirstOrDefault() != null)
            {
                //Pull out the description value
                return ((DescriptionAttribute)attrs.Where(t=>t.GetType() == typeof(DescriptionAttribute)).FirstOrDefault()).Description;
            }
        }
        //If we have no description attribute, just return the ToString of the enum
        return enumerationValue.ToString();

我使用系统中的Description属性。ComponentModel名称空间。简单地装饰enum:

private enum PublishStatusValue
{
    [Description("Not Completed")]
    NotCompleted,
    Completed,
    Error
};

然后使用下面的代码来检索它:

public static string GetDescription<T>(this T enumerationValue)
    where T : struct
{
    Type type = enumerationValue.GetType();
    if (!type.IsEnum)
    {
        throw new ArgumentException("EnumerationValue must be of Enum type", "enumerationValue");
    }

    //Tries to find a DescriptionAttribute for a potential friendly name
    //for the enum
    MemberInfo[] memberInfo = type.GetMember(enumerationValue.ToString());
    if (memberInfo != null && memberInfo.Length > 0)
    {
        object[] attrs = memberInfo[0].GetCustomAttributes(typeof(DescriptionAttribute), false);

        if (attrs != null && attrs.Length > 0)
        {
            //Pull out the description value
            return ((DescriptionAttribute)attrs[0]).Description;
        }
    }
    //If we have no description attribute, just return the ToString of the enum
    return enumerationValue.ToString();
}

根据本文档:https://learn.microsoft.com/pt-br/dotnet/api/system.enum.tostring?view=netframework-4.8

可以使用如下格式将枚举数转换为字符串:

public enum Example
{
    Example1,
    Example2
}

Console.WriteLine(Example.Example1.ToString("g"));

//Outputs: "Example1"

你可以在这个链接中看到所有可能的格式:https://learn.microsoft.com/pt-br/dotnet/api/system.string?view=netframework-4.8

如果你想要完全可定制的东西，试试我的解决方案:

基本上，这篇文章概述了如何将Description属性附加到每个枚举，并提供了从枚举映射到描述的通用方法。

使用枚举。GetName

从上面的链接…

using System;

public class GetNameTest {
    enum Colors { Red, Green, Blue, Yellow };
    enum Styles { Plaid, Striped, Tartan, Corduroy };

    public static void Main() {

        Console.WriteLine("The 4th value of the Colors Enum is {0}", Enum.GetName(typeof(Colors), 3));
        Console.WriteLine("The 4th value of the Styles Enum is {0}", Enum.GetName(typeof(Styles), 3));
    }
}
// The example displays the following output:
//       The 4th value of the Colors Enum is Yellow
//       The 4th value of the Styles Enum is Corduroy
