好吧，我真的是姗姗姗迟了，但无论如何，我已经在博客上讨论了这个主题，在这个主题中我创建了一个EnumHelper类，它可以实现非常简单的转换。

http://jnye.co/Posts/4/creating-a-dropdown-list-from-an-enum-in-mvc-and-c%23

在你的控制器中:

//If you don't have an enum value use the type
ViewBag.DropDownList = EnumHelper.SelectListFor<MyEnum>();

//If you do have an enum value use the value (the value will be marked as selected)    
ViewBag.DropDownList = EnumHelper.SelectListFor(MyEnum.MyEnumValue);

在您看来:

@Html.DropDownList("DropDownList")
@* OR *@
@Html.DropDownListFor(m => m.Property, ViewBag.DropDownList as SelectList, null)

helper类:

public static class EnumHelper
{
    // Get the value of the description attribute if the   
    // enum has one, otherwise use the value.  
    public static string GetDescription<TEnum>(this TEnum value)
    {
        var fi = value.GetType().GetField(value.ToString());

        if (fi != null)
        {
            var attributes = (DescriptionAttribute[])fi.GetCustomAttributes(typeof(DescriptionAttribute), false);

            if (attributes.Length > 0)
            {
                return attributes[0].Description;
            }
        }

        return value.ToString();
    }

    /// <summary>
    /// Build a select list for an enum
    /// </summary>
    public static SelectList SelectListFor<T>() where T : struct
    {
        Type t = typeof(T);
        return !t.IsEnum ? null
                         : new SelectList(BuildSelectListItems(t), "Value", "Text");
    }

    /// <summary>
    /// Build a select list for an enum with a particular value selected 
    /// </summary>
    public static SelectList SelectListFor<T>(T selected) where T : struct
    {
        Type t = typeof(T);
        return !t.IsEnum ? null
                         : new SelectList(BuildSelectListItems(t), "Text", "Value", selected.ToString());
    }

    private static IEnumerable<SelectListItem> BuildSelectListItems(Type t)
    {
        return Enum.GetValues(t)
                   .Cast<Enum>()
                   .Select(e => new SelectListItem { Value = e.ToString(), Text = e.GetDescription() });
    }
}

        ////  ViewModel

        public class RegisterViewModel
          {

        public RegisterViewModel()
          {
              ActionsList = new List<SelectListItem>();
          }

        public IEnumerable<SelectListItem> ActionsList { get; set; }

        public string StudentGrade { get; set; }

           }

       //// Enum Class

        public enum GradeTypes
             {
               A,
               B,
               C,
               D,
               E,
               F,
               G,
               H
            }

         ////Controller action 

           public ActionResult Student()
               {
    RegisterViewModel vm = new RegisterViewModel();
    IEnumerable<GradeTypes> actionTypes = Enum.GetValues(typeof(GradeTypes))
                                         .Cast<GradeTypes>();                  
    vm.ActionsList = from action in actionTypes
                     select new SelectListItem
                     {
                         Text = action.ToString(),
                         Value = action.ToString()
                     };
              return View(vm);
               }

         ////// View Action

   <div class="form-group">
                            <label class="col-lg-2 control-label" for="hobies">Student Grade:</label>
                            <div class="col-lg-10">
                               @Html.DropDownListFor(model => model.StudentGrade, Model.ActionsList, new { @class = "form-control" })
                            </div>

这个扩展方法的另一个修复-当前版本没有选择枚举的当前值。我修正了最后一行:

public static SelectList ToSelectList<TEnum>(this TEnum enumObj) where TEnum : struct
    {
        if (!typeof(TEnum).IsEnum) throw new ArgumentException("An Enumeration type is required.", "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())).ToString());
    }

所以没有扩展函数，如果你正在寻找简单和容易..这就是我所做的

<%= Html.DropDownListFor(x => x.CurrentAddress.State, new SelectList(Enum.GetValues(typeof(XXXXX.Sites.YYYY.Models.State))))%>

where XXXXX.Sites.YYYY.Models.State是enum

也许做辅助函数更好，但是当时间很短的时候，这将完成工作。

你也可以在Griffin.MvcContrib中使用我的自定义HtmlHelpers。以下代码:

@Html2.CheckBoxesFor(model => model.InputType) <br />
@Html2.RadioButtonsFor(model => model.InputType) <br />
@Html2.DropdownFor(model => model.InputType) <br />

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。
