　　看一下Controller例子

        [ChildActionOnly]
        public List<SelectListItem> LoadItemStatus()
        {
            List<SelectListItem> items = new List<SelectListItem>() {
                new SelectListItem() { Value = "", Text = "--所有--" },
                new SelectListItem() { Value = "待审核", Text = "--待审核--" },
                new SelectListItem() { Value = "审核通过", Text = "--审核通过--" },
                new SelectListItem() { Value = "审核不通过", Text = "--审核不通过--" }
            };

            return items;
        }

        public ActionResult Index()
        {
            List<SelectListItem> items = new List<SelectListItem>() {
                new SelectListItem() { Value = "", Text = "--所有--" },
                new SelectListItem() { Value = "待审核", Text = "--待审核--" },
                new SelectListItem() { Value = "审核通过", Text = "--审核通过--" },
                new SelectListItem() { Value = "审核不通过", Text = "--审核不通过--" }
            };

            ViewData["Categories"] = new SelectList(items, "Text", "Value");

            return View();
        }

　　看一下

@*@Html.DropDownList("Category", ViewData["Categories"] as SelectList,"--请选择--",new { @class = "my-select-css-class" } )*@
