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();
}

最简单的方法是将这个扩展类包含到你的项目中，它将与项目中的任何枚举一起工作:

public static class EnumExtensions
{
    public static string ToFriendlyString(this Enum code)
    {
        return Enum.GetName(code.GetType(), code);
    }
}

用法:

enum ExampleEnum
{
    Demo = 0,
    Test = 1, 
    Live = 2
}

...

ExampleEnum ee = ExampleEnum.Live;
Console.WriteLine(ee.ToFriendlyString());

更简洁的总结是:

using System;
using System.Reflection;

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

public static class EnumExtender
{
    public static string ToText(this Enum enumeration)
    {
        var memberInfo = enumeration.GetType().GetMember(enumeration.ToString());
        if (memberInfo.Length <= 0) return enumeration.ToString();

        var attributes = memberInfo[0].GetCustomAttributes(typeof(TextAttribute), false);
        return attributes.Length > 0 ? ((TextAttribute)attributes[0]).Text : enumeration.ToString();
    }
}

用法与下划线所描述的相同。

这里最简单的解决方案是使用自定义扩展方法(至少在。net 3.5中-您可以将其转换为早期框架版本的静态帮助器方法)。

public static string ToCustomString(this PublishStatusses value)
{
    switch(value)
    {
        // Return string depending on value.
    }
    return null;
}

我在这里假设您希望返回enum值的实际名称以外的内容(您可以通过简单地调用ToString来获得)。

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();

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
