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)

如果你想添加本地化支持，只需更改s.toString()方法如下所示:

ResourceManager rManager = new ResourceManager(typeof(Resources));
var dayTypes = from OperatorCalendarDay.OperatorDayType s in Enum.GetValues(typeof(OperatorCalendarDay.OperatorDayType))
               select new { ID = s, Name = rManager.GetString(s.ToString()) };

在这里typeof(Resources)是你想要加载的资源，然后你得到本地化的String，如果你的枚举器有多个单词的值也很有用。

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);
}

        ////  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>

我想以一种不同的方式回答这个问题，用户不需要在控制器或Linq表达式中做任何事情。这种方式……

我有一个ENUM

public enum AccessLevelEnum
    {
        /// <summary>
        /// The user cannot access
        /// </summary>
        [EnumMember, Description("No Access")]
        NoAccess = 0x0,

        /// <summary>
        /// The user can read the entire record in question
        /// </summary>
        [EnumMember, Description("Read Only")]
        ReadOnly = 0x01,

        /// <summary>
        /// The user can read or write
        /// </summary>
        [EnumMember, Description("Read / Modify")]
        ReadModify = 0x02,

        /// <summary>
        /// User can create new records, modify and read existing ones
        /// </summary>
        [EnumMember, Description("Create / Read / Modify")]
        CreateReadModify = 0x04,

        /// <summary>
        /// User can read, write, or delete
        /// </summary>
        [EnumMember, Description("Create / Read / Modify / Delete")]
        CreateReadModifyDelete = 0x08,

        /*/// <summary>
        /// User can read, write, or delete
        /// </summary>
        [EnumMember, Description("Create / Read / Modify / Delete / Verify / Edit Capture Value")]
        CreateReadModifyDeleteVerify = 0x16*/
    }

现在我可以使用这个enum简单地创建一个下拉列表。

@Html.DropDownList("accessLevel",new SelectList(AccessLevelEnum.GetValues(typeof(AccessLevelEnum))),new { @class = "form-control" })

OR

@Html.DropDownListFor(m=>m.accessLevel,new SelectList(AccessLevelEnum.GetValues(typeof(AccessLevelEnum))),new { @class = "form-control" })

如果你想让一个索引被选中，那么试试这个

@Html.DropDownListFor(m=>m.accessLevel,new SelectList(AccessLevelEnum.GetValues(typeof(AccessLevelEnum)) , AccessLevelEnum.NoAccess ),new { @class = "form-control" })

这里我使用了AccessLevelEnum。NoAccess作为默认选择下拉菜单的额外参数。

@Html.DropdownListFor(model=model->Gender,new List<SelectListItem>
{
 new ListItem{Text="Male",Value="Male"},
 new ListItem{Text="Female",Value="Female"},
 new ListItem{Text="--- Select -----",Value="-----Select ----"}
}
)
