这应该能满足你的需要。

try
{
  var enumType = typeof(FunkyAttributesEnum);
  var memberInfos = 
  enumType.GetMember(FunkyAttributesEnum.NameWithoutSpaces1.ToString());
  var enumValueMemberInfo = memberInfos.FirstOrDefault(m => 
  m.DeclaringType == enumType);
  var valueAttributes = 
  enumValueMemberInfo.GetCustomAttributes(typeof(DescriptionAttribute), false);
  var description = ((DescriptionAttribute)valueAttributes[0]).Description;
}
catch
{
    return FunkyAttributesEnum.NameWithoutSpaces1.ToString()
}

添加我的解决方案的Net Framework和NetCore。

我在我的Net Framework实现中使用了这个:

public static class EnumerationExtension
{
    public static string Description( this Enum value )
    {
        // get attributes  
        var field = value.GetType().GetField( value.ToString() );
        var attributes = field.GetCustomAttributes( typeof( DescriptionAttribute ), false );

        // return description
        return attributes.Any() ? ( (DescriptionAttribute)attributes.ElementAt( 0 ) ).Description : "Description Not Found";
    }
}

这并不适用于NetCore，所以我修改了它，这样做:

public static class EnumerationExtension
{
    public static string Description( this Enum value )
    {
        // get attributes  
        var field = value.GetType().GetField( value.ToString() );
        var attributes = field.GetCustomAttributes( false );

        // Description is in a hidden Attribute class called DisplayAttribute
        // Not to be confused with DisplayNameAttribute
        dynamic displayAttribute = null;

        if (attributes.Any())
        {
            displayAttribute = attributes.ElementAt( 0 );
        }

        // return description
        return displayAttribute?.Description ?? "Description Not Found";
    }
}

枚举的例子:

public enum ExportTypes
{
    [Display( Name = "csv", Description = "text/csv" )]
    CSV = 0
}

使用任何静态添加:

var myDescription = myEnum.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>
}

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);

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

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));

    }
