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 />

生成:

https://github.com/jgauffin/griffin.mvccontrib

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

这是我的helper方法。 我用这个:

var values = from int e in Enum.GetValues(typeof(TEnum))
             select new { ID = e, Name = Enum.GetName(typeof(TEnum), e) };

而不是:

var values = from TEnum e in Enum.GetValues(typeof(TEnum))
           select new { ID = (int)Enum.Parse(typeof(TEnum),e.ToString())
                     , Name = e.ToString() };

下面就是:

public static SelectList ToSelectList<TEnum>(this TEnum self) where TEnum : struct
    {
        if (!typeof(TEnum).IsEnum)
        {
            throw new ArgumentException("self must be enum", "self");
        }

        Type t = typeof(TEnum);

        var values = from int e in Enum.GetValues(typeof(TEnum))
                     select new { ID = e, Name = Enum.GetName(typeof(TEnum), e) };

        return new SelectList(values, "ID", "Name", self);
    }

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。

这是Razor的版本:

@{
    var itemTypesList = new List<SelectListItem>();
    itemTypesList.AddRange(Enum.GetValues(typeof(ItemTypes)).Cast<ItemTypes>().Select(
                (item, index) => new SelectListItem
                {
                    Text = item.ToString(),
                    Value = (index).ToString(),
                    Selected = Model.ItemTypeId == index
                }).ToList());
 }


@Html.DropDownList("ItemTypeId", itemTypesList)

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() });
    }
}
