谢谢你的解决方案，它可以完美地应用在我的情况。唯一的问题是我必须把它翻译成VB。但现在已经完成了，为了节省其他人的时间(以防他们需要)，我把它放在这里:

Imports System.Runtime.CompilerServices
Imports System.ComponentModel
Imports System.Linq.Expressions

Public Module HtmlHelpers
    Private Function GetNonNullableModelType(modelMetadata As ModelMetadata) As Type
        Dim realModelType = modelMetadata.ModelType

        Dim underlyingType = Nullable.GetUnderlyingType(realModelType)

        If Not underlyingType Is Nothing Then
            realModelType = underlyingType
        End If

        Return realModelType
    End Function

    Private ReadOnly SingleEmptyItem() As SelectListItem = {New SelectListItem() With {.Text = "", .Value = ""}}

    Private Function GetEnumDescription(Of TEnum)(value As TEnum) As String
        Dim fi = value.GetType().GetField(value.ToString())

        Dim attributes = DirectCast(fi.GetCustomAttributes(GetType(DescriptionAttribute), False), DescriptionAttribute())

        If Not attributes Is Nothing AndAlso attributes.Length > 0 Then
            Return attributes(0).Description
        Else
            Return value.ToString()
        End If
    End Function

    <Extension()>
    Public Function EnumDropDownListFor(Of TModel, TEnum)(ByVal htmlHelper As HtmlHelper(Of TModel), expression As Expression(Of Func(Of TModel, TEnum))) As MvcHtmlString
        Return EnumDropDownListFor(htmlHelper, expression, Nothing)
    End Function

    <Extension()>
    Public Function EnumDropDownListFor(Of TModel, TEnum)(ByVal htmlHelper As HtmlHelper(Of TModel), expression As Expression(Of Func(Of TModel, TEnum)), htmlAttributes As Object) As MvcHtmlString
        Dim metaData As ModelMetadata = ModelMetadata.FromLambdaExpression(expression, htmlHelper.ViewData)
        Dim enumType As Type = GetNonNullableModelType(metaData)
        Dim values As IEnumerable(Of TEnum) = [Enum].GetValues(enumType).Cast(Of TEnum)()

        Dim items As IEnumerable(Of SelectListItem) = From value In values
            Select New SelectListItem With
            {
                .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 Then
            items = SingleEmptyItem.Concat(items)
        End If

        Return htmlHelper.DropDownListFor(expression, items, htmlAttributes)
    End Function
End Module

你可以这样使用它:

@Html.EnumDropDownListFor(Function(model) (model.EnumField))

这里是Martin Faartoft的变种，你可以放自定义标签，这对本地化很好。

public static class EnumHtmlHelper
{
    public static SelectList ToSelectList<TEnum>(this TEnum enumObj, Dictionary<int, string> customLabels)
        where TEnum : struct, IComparable, IFormattable, IConvertible
    {
        var values = from TEnum e in Enum.GetValues(typeof(TEnum))
                     select new { Id = e, Name = customLabels.First(x => x.Key == Convert.ToInt32(e)).Value.ToString() };

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

视图中使用:

@Html.DropDownListFor(m => m.Category, Model.Category.ToSelectList(new Dictionary<int, string>() { 
          { 1, ContactResStrings.FeedbackCategory }, 
          { 2, ContactResStrings.ComplainCategory }, 
          { 3, ContactResStrings.CommentCategory },
          { 4, ContactResStrings.OtherCategory }
      }), new { @class = "form-control" })
@Html.ValidationMessageFor(m => m.Category)

一个超级简单的方法来做到这一点-没有所有的扩展似乎过度的东西是:

你的枚举:

    public enum SelectedLevel
    {
       Level1,
       Level2,
       Level3,
       Level4
    }

在你的控制器内部，将Enum绑定到一个List:

    List<SelectedLevel> myLevels = Enum.GetValues(typeof(SelectedLevel)).Cast<SelectedLevel>().ToList();

然后把它扔进ViewBag:

    ViewBag.RequiredLevel = new SelectList(myLevels);

最后简单地将它绑定到视图:

    @Html.DropDownList("selectedLevel", (SelectList)ViewBag.RequiredLevel, new { @class = "form-control" })

这是迄今为止我发现的最简单的方法，不需要任何扩展或任何疯狂的东西。

更新:见安德鲁斯下面的评论。

我遇到了同样的问题，发现了这个问题，并认为Ash提供的解决方案不是我要寻找的;与内置的HTML . dropdownlist()函数相比，必须自己创建HTML意味着更少的灵活性。

c# 3等使得这非常简单。我有一个名为TaskStatus的枚举:

var statuses = from TaskStatus s in Enum.GetValues(typeof(TaskStatus))
               select new { ID = s, Name = s.ToString() };
ViewData["taskStatus"] = new SelectList(statuses, "ID", "Name", task.Status);

这将创建一个很好的ol' SelectList，可以像在视图中一样使用:

<td><b>Status:</b></td><td><%=Html.DropDownList("taskStatus")%></td></tr>

匿名类型和LINQ使它更加优雅。无意冒犯，阿什。：）

这是符文和价格的答案改变使用Enum int值作为ID。

示例枚举:

public enum ItemTypes
{
    Movie = 1,
    Game = 2,
    Book = 3
}

扩展方法:

    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", (int)Enum.Parse(typeof(TEnum), enumObj.ToString()));
    }

用法示例:

 <%=  Html.DropDownList("MyEnumList", ItemTypes.Game.ToSelectList()) %>

记住导入包含Extension方法的命名空间

<%@ Import Namespace="MyNamespace.LocationOfExtensionMethod" %>

生成的HTML示例:

<select id="MyEnumList" name="MyEnumList">
    <option value="1">Movie</option>
    <option selected="selected" value="2">Game</option>
    <option value="3">Book </option>
</select>

请注意，用于调用ToSelectList的项就是选中的项。

在MVC4中，我会这样做

@Html.DropDownList("RefType", new SelectList(Enum.GetValues(typeof(WebAPIApp.Models.RefType))), " Select", new { @class = "form-control" })

public enum RefType
    {
        Web = 3,
        API = 4,
        Security = 5,
        FE = 6
    }

    public class Reference
    {
        public int Id { get; set; }
        public RefType RefType { get; set; }
    }
