public enum DataFilters
    {
        [Display(Name= "Equals")]
        Equals = 1,// Display Name and Enum Name are same 
        [Display(Name= "Does Not Equal")]
        DoesNotEqual = 2, // Display Name and Enum Name are different             
    }

在这个例子中它会产生错误1 "等于"

public static string GetDisplayName(this Enum enumValue)
    {
        var enumMember = enumValue.GetType().GetMember(enumValue.ToString()).First();
        return enumMember.GetCustomAttribute<DisplayAttribute>() != null ? enumMember.GetCustomAttribute<DisplayAttribute>().Name : enumMember.Name;
    }

如果它是相同的返回enum名称而不是显示名称因为 enumMember.GetCustomAttribute () 如果displayname和enum name相同，则返回null .....

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];
    }
}

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。

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>
}

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

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);
