或者，你可以这样做:

Dictionary<FunkyAttributesEnum, string> description = new Dictionary<FunkyAttributesEnum, string>()
    {
      { FunkyAttributesEnum.NameWithoutSpaces1, "Name With Spaces1" },
      { FunkyAttributesEnum.NameWithoutSpaces2, "Name With Spaces2" },
    };

并使用以下语句获取描述:

string s = description[FunkyAttributesEnum.NameWithoutSpaces1];

在我看来，这是一种更有效的方式去做你想要完成的事情，因为不需要思考。

下面是AdamCrawford的答案的。net核心版本，使用System.Reflection.TypeExtensions;

public static class EnumHelper
{
    /// <summary>
    /// Gets an attribute on an enum field value
    /// </summary>
    /// <typeparam name="T">The type of the attribute you want to retrieve</typeparam>
    /// <param name="enumVal">The enum value</param>
    /// <returns>The attribute of type T that exists on the enum value</returns>
    /// <example>string desc = myEnumVariable.GetAttributeOfType<DescriptionAttribute>().Description;</example>
    public static T GetAttributeOfType<T>(this Enum enumVal) where T : System.Attribute
    {
        var type = enumVal.GetType();
        var memInfo = type.GetMember(enumVal.ToString());
        IEnumerable<Attribute> attributes = memInfo[0].GetCustomAttributes(typeof(T), false);
        return (T)attributes?.ToArray()[0];
    }
}

流利的一句话…

这里我使用的DisplayAttribute包含Name和Description属性。

public static DisplayAttribute GetDisplayAttributesFrom(this Enum enumValue, Type enumType)
{
    return enumType.GetMember(enumValue.ToString())
                   .First()
                   .GetCustomAttribute<DisplayAttribute>();
}

例子

public enum ModesOfTransport
{
    [Display(Name = "Driving",    Description = "Driving a car")]        Land,
    [Display(Name = "Flying",     Description = "Flying on a plane")]    Air,
    [Display(Name = "Sea cruise", Description = "Cruising on a dinghy")] Sea
}

void Main()
{
    ModesOfTransport TransportMode = ModesOfTransport.Sea;
    DisplayAttribute metadata = TransportMode.GetDisplayAttributesFrom(typeof(ModesOfTransport));
    Console.WriteLine("Name: {0} \nDescription: {1}", metadata.Name, metadata.Description);
}

输出

Name: Sea cruise 
Description: Cruising on a dinghy

这就是我在不使用。net core 3.1的自定义helper或扩展的情况下解决它的方法。

类

public enum YourEnum
{
    [Display(Name = "Suryoye means Arameans")]
    SURYOYE = 0,
    [Display(Name = "Oromoye means Syriacs")]
    OROMOYE = 1,
}

剃须刀

@using Enumerations

foreach (var name in Html.GetEnumSelectList(typeof(YourEnum)))
{
    <h1>@name.Text</h1>
}

或者，你可以这样做:

List<SelectListItem> selectListItems = new List<SelectListItem>();

    foreach (var item in typeof(PaymentTerm).GetEnumValues())
    {
        var type = item.GetType();
        var name = type.GetField(item.ToString()).GetCustomAttributesData().FirstOrDefault()?.NamedArguments.FirstOrDefault().TypedValue.Value.ToString();
        selectListItems.Add(new SelectListItem(name, type.Name));

    }

朋友们，如果有帮助的话，我将与你们分享我的解决方案: Custom属性的定义:

    [AttributeUsage(AttributeTargets.Field,AllowMultiple = false)]
public class EnumDisplayName : Attribute
{
    public string Name { get; private set; }
    public EnumDisplayName(string name)
    {
        Name = name;
    }
}

现在因为我需要它在HtmlHelper扩展的HtmlHelper定义内:

public static class EnumHelper
{
    public static string EnumDisplayName(this HtmlHelper helper,EPriceType priceType)
    {
        //Get every fields from enum
        var fields = priceType.GetType().GetFields();
        //Foreach field skipping 1`st fieldw which keeps currently sellected value
        for (int i = 0; i < fields.Length;i++ )
        {
            //find field with same int value
            if ((int)fields[i].GetValue(priceType) == (int)priceType)
            {
                //get attributes of found field
                var attributes = fields[i].GetCustomAttributes(false);
                if (attributes.Length > 0)
                {
                    //return name of found attribute
                    var retAttr = (EnumDisplayName)attributes[0];
                    return retAttr.Name;
                }
            }
        }
        //throw Error if not found
        throw new Exception("Błąd podczas ustalania atrybutów dla typu ceny allegro");
    }
}

希望能有所帮助
