你可以使用Type。GetMember方法，然后使用反射获取属性信息:

// display attribute of "currentPromotion"

var type = typeof(UserPromotion);
var memberInfo = type.GetMember(currentPromotion.ToString());
var attributes = memberInfo[0].GetCustomAttributes(typeof(DisplayAttribute), false);
var description = ((DisplayAttribute)attributes[0]).Name;

获取Enum值的属性

如何使MVC3 DisplayFor显示一个Enum的显示属性的值?

如果你使用的是MVC 5.1或更高版本，有一个更简单、更清晰的方法:只使用数据注释(来自System.ComponentModel.DataAnnotations命名空间)，如下所示:

public enum Color
{
    [Display(Name = "Dark red")]
    DarkRed,
    [Display(Name = "Very dark red")]
    VeryDarkRed,
    [Display(Name = "Red or just black?")]
    ReallyDarkRed
}

在视图中，把它放到合适的html helper中:

@Html.EnumDropDownListFor(model => model.Color)

你可以使用Type。GetMember方法，然后使用反射获取属性信息:

// display attribute of "currentPromotion"

var type = typeof(UserPromotion);
var memberInfo = type.GetMember(currentPromotion.ToString());
var attributes = memberInfo[0].GetCustomAttributes(typeof(DisplayAttribute), false);
var description = ((DisplayAttribute)attributes[0]).Name;

获取Enum值的属性

如何使MVC3 DisplayFor显示一个Enum的显示属性的值?

一行-流畅的语法

public static class Extensions
{
    /// <summary>
    ///     A generic extension method that aids in reflecting 
    ///     and retrieving any attribute that is applied to an `Enum`.
    /// </summary>
    public static TAttribute GetAttribute<TAttribute>(this Enum enumValue) 
            where TAttribute : Attribute
    {
        return enumValue.GetType()
                        .GetMember(enumValue.ToString())
                        .First()
                        .GetCustomAttribute<TAttribute>();
    }
}

例子

public enum Season 
{
   [Display(Name = "It's autumn")]
   Autumn,

   [Display(Name = "It's winter")]
   Winter,

   [Display(Name = "It's spring")]
   Spring,

   [Display(Name = "It's summer")]
   Summer
}

public class Foo 
{
    public Season Season = Season.Summer;

    public void DisplayName()
    {
        var seasonDisplayName = Season.GetAttribute<DisplayAttribute>();
        Console.WriteLine("Which season is it?");
        Console.WriteLine (seasonDisplayName.Name);
    } 
}

输出

现在是哪个季节? 现在是夏天

从上面将所有边情况组合在一起:

枚举包含基对象成员名的成员(Equals, ToString) 可选显示属性

这是我的代码:

public enum Enum
{
    [Display(Name = "What a weird name!")]
    ToString,

    Equals
}

public static class EnumHelpers
{
    public static string GetDisplayName(this Enum enumValue)
    {
        var enumType = enumValue.GetType();

        return enumType
                .GetMember(enumValue.ToString())
                .Where(x => x.MemberType == MemberTypes.Field && ((FieldInfo)x).FieldType == enumType)
                .First()
                .GetCustomAttribute<DisplayAttribute>()?.Name ?? enumValue.ToString();
    }
}

void Main()
{
    Assert.Equals("What a weird name!", Enum.ToString.GetDisplayName());
    Assert.Equals("Equals", Enum.Equals.GetDisplayName());
}

这可能是欺骗，但它是有效的:

 @foreach (var yourEnum in Html.GetEnumSelectList<YourEnum>())
 {
     @yourEnum.Text
 }
