另一篇文章是Java。在c#中，你不能把方法放在枚举中。

就像这样做:

PublishStatusses status = ...
String s = status.ToString();

如果您想为枚举值使用不同的显示值，您可以使用Attributes和Reflection。

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();

我创建了一个反向扩展方法来将描述转换回enum值:

public static T ToEnumValue<T>(this string enumerationDescription) where T : struct
{
    var type = typeof(T);

    if (!type.IsEnum)
        throw new ArgumentException("ToEnumValue<T>(): Must be of enum type", "T");

    foreach (object val in System.Enum.GetValues(type))
        if (val.GetDescription<T>() == enumerationDescription)
            return (T)val;

    throw new ArgumentException("ToEnumValue<T>(): Invalid description for enum " + type.Name, "enumerationDescription");
}

用于标记枚举，包括。

    public static string Description(this Enum value)
    {
        Type type = value.GetType();

        List<string> res = new List<string>();
        var arrValue = value.ToString().Split(',').Select(v=>v.Trim());
        foreach (string strValue in arrValue)
        {
            MemberInfo[] memberInfo = type.GetMember(strValue);
            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)
                {
                    res.Add(((DescriptionAttribute)attrs.Where(t => t.GetType() == typeof(DescriptionAttribute)).FirstOrDefault()).Description);
                }
                else
                    res.Add(strValue);
            }
            else
                res.Add(strValue);
        }

        return res.Aggregate((s,v)=>s+", "+v);
    }

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

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
