我最终创建了扩展方法来执行这里基本上可以接受的答案。Gist的后半部分专门处理Enum。

现在这个特性在MVC 5.1中通过@Html.EnumDropDownListFor()得到了开箱即用的支持。

根据上面的投票，微软花了5年的时间来实现这样一个如此受欢迎的功能，真是太遗憾了!

我找到的最好的解决办法就是把这个博客和西蒙·戈德斯通的答案结合起来。

这允许在模型中使用枚举。从本质上讲，这个想法是使用整数属性和枚举，并模拟整数属性。

然后使用[System.ComponentModel。属性用于用你的显示文本注释模型，并在你的视图中使用“EnumDropDownListFor”扩展。

这使得视图和模型都非常可读和可维护。

模型:

public enum YesPartialNoEnum
{
    [Description("Yes")]
    Yes,
    [Description("Still undecided")]
    Partial,
    [Description("No")]
    No
}

//........

[Display(Name = "The label for my dropdown list")]
public virtual Nullable<YesPartialNoEnum> CuriousQuestion{ get; set; }
public virtual Nullable<int> CuriousQuestionId
{
    get { return (Nullable<int>)CuriousQuestion; }
    set { CuriousQuestion = (Nullable<YesPartialNoEnum>)value; }
}

观点:

@using MyProject.Extensions
{
//...
    @Html.EnumDropDownListFor(model => model.CuriousQuestion)
//...
}

扩展(直接来自Simon Goldstone的回答，为完整起见，此处包含):

        {
            Type realModelType = modelMetadata.ModelType;

            Type underlyingType = Nullable.GetUnderlyingType(realModelType);
            if (underlyingType != null)
            {
                realModelType = underlyingType;
            }
            return realModelType;
        }

        private static readonly SelectListItem[] SingleEmptyItem = new[] { new SelectListItem { Text = "", Value = "" } };

        public static string GetEnumDescription<TEnum>(TEnum value)
        {
            FieldInfo fi = value.GetType().GetField(value.ToString());

            DescriptionAttribute[] attributes = (DescriptionAttribute[])fi.GetCustomAttributes(typeof(DescriptionAttribute), false);

            if ((attributes != null) && (attributes.Length > 0))
                return attributes[0].Description;
            else
                return value.ToString();
        }

        public static MvcHtmlString EnumDropDownListFor<TModel, TEnum>(this HtmlHelper<TModel> htmlHelper, Expression<Func<TModel, TEnum>> expression)
        {
            return EnumDropDownListFor(htmlHelper, expression, null);
        }

        public static MvcHtmlString EnumDropDownListFor<TModel, TEnum>(this HtmlHelper<TModel> htmlHelper, Expression<Func<TModel, TEnum>> expression, object htmlAttributes)
        {
            ModelMetadata metadata = ModelMetadata.FromLambdaExpression(expression, htmlHelper.ViewData);
            Type enumType = GetNonNullableModelType(metadata);
            IEnumerable<TEnum> values = Enum.GetValues(enumType).Cast<TEnum>();

            IEnumerable<SelectListItem> items = from value in values
                                                select new SelectListItem
                                                {
                                                    Text = GetEnumDescription(value),
                                                    Value = value.ToString(),
                                                    Selected = value.Equals(metadata.Model)
                                                };

            // If the enum is nullable, add an 'empty' item to the collection
            if (metadata.IsNullableValueType)
                items = SingleEmptyItem.Concat(items);

            return htmlHelper.DropDownListFor(expression, items, htmlAttributes);
        }
    }
}

使用Prise的扩展方法来解决获取数字而不是文本的问题。

public static SelectList ToSelectList<TEnum>(this TEnum enumObj)
{
  var values = from TEnum e in Enum.GetValues(typeof(TEnum))
               select new { ID = (int)Enum.Parse(typeof(TEnum),e.ToString())
                         , Name = e.ToString() };

  return new SelectList(values, "Id", "Name", enumObj);
}

@Html.DropDownListFor(model => model.Type, Enum.GetNames(typeof(Rewards.Models.PropertyType)).Select(e => new SelectListItem { Text = e }))

@Html.DropDownListFor(model => model.MaritalStatus, new List<SelectListItem> 
{  

new SelectListItem { Text = "----Select----", Value = "-1" },


new SelectListItem { Text = "Marrid", Value = "M" },


 new SelectListItem { Text = "Single", Value = "S" }

})
