1.拓展EnumHelper

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), "Value", "Text", 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() });

    }

}

2.在控制器中添加

ViewBag.DropDownList = EnumHelper.SelectListFor<MyEnum>();

//或者

ViewBag.DropDownList = EnumHelper.SelectListFor(MyEnum.MyEnumValue);

3.在视图中添加

@Html.DropDownList("DropDownList")

@* OR *@

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