新手剛學mvc

controller中：

 public ActionResult Index(string namelist){            var list = new List<string>();            var listQry = from d in db.Movies                          orderby d.name                          select d.name;            list.AddRange(listQry.Distinct());            ViewBag.namelist = new SelectList(list);            var movies = from m in db.Movies                         select m;            if (!String.IsNullOrEmpty(namelist))            {                movies = movies.Where(x => x.name == namelist);            }            return View(movies);            }

html中：

@using (Html.BeginForm("Index", "Movies", FormMethod.Get)) {         <p>            下拉式清單：@Html.DropDownList("namelist", "All")            <input type="submit" value="查詢"><br/>        </p>}

All是下拉式清單顯示的預設值。
