Hi

Try this:

return View(ts.AsEnumerable());

or like this:

        public ActionResult Index()
        {
            IEnumerable<SelectListItem> ts = (from s in Enumerable.Range(1, 10)
                                             select new SelectListItem
                                             {
                                                 Text = s.ToString(),
                                                 Value = s.ToString(),
                                             });
            ts.First().Selected = true;
            return View(ts);
        ｝

Hope it can help.
