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。

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));

    }

如果你想要完整的名单你可以这样做

typeof (PharmacyConfigurationKeys).GetFields()
        .Where(x => x.GetCustomAttributes(false).Any(y => typeof(DescriptionAttribute) == y.GetType()))
        .Select(x => ((DescriptionAttribute)x.GetCustomAttributes(false)[0]).Description);

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>
}

利用一些较新的c#语言特性，你可以减少行数:

public static TAttribute GetEnumAttribute<TAttribute>(this Enum enumVal) where TAttribute : Attribute
{
    var memberInfo = enumVal.GetType().GetMember(enumVal.ToString());
    return memberInfo[0].GetCustomAttributes(typeof(TAttribute), false).OfType<TAttribute>().FirstOrDefault();
}

public static string GetEnumDescription(this Enum enumValue) => enumValue.GetEnumAttribute<DescriptionAttribute>()?.Description ?? enumValue.ToString();

对于一些程序员的幽默，一行代码就像一个笑话:

public static string GetDescription(this Enum value) => value.GetType().GetMember(value.ToString()).First().GetCustomAttribute<DescriptionAttribute>() is DescriptionAttribute attribute ? attribute.Description : string.Empty;

以更易读的形式:

using System;
using System.ComponentModel;
using System.Linq;
using System.Reflection;

public static class EnumExtensions
{
    // get description from enum:

    public static string GetDescription(this Enum value)
    {
        return value.GetType().
            GetMember(value.ToString()).
            First().
            GetCustomAttribute<DescriptionAttribute>() is DescriptionAttribute attribute
            ? attribute.Description
            : throw new Exception($"Enum member '{value.GetType()}.{value}' doesn't have a [DescriptionAttribute]!");
    }

    // get enum from description:

    public static T GetEnum<T>(this string description) where T : Enum
    {
        foreach (FieldInfo fieldInfo in typeof(T).GetFields())
        {
            if (fieldInfo.GetCustomAttribute<DescriptionAttribute>() is DescriptionAttribute attribute && attribute.Description == description)
                return (T)fieldInfo.GetRawConstantValue();
        }

        throw new Exception($"Enum '{typeof(T)}' doesn't have a member with a [DescriptionAttribute('{description}')]!");
    }
}
