            new Locations() {Id = 18, Name = "Conventory"}
        };
    }

Controller:

public class DefaultController : Controller
   {
       public ActionResult Index()
       {
           return View();
       }

       public JsonResult Search(string term)
       {
           Locations l = new Locations();
           List<string> Loc;
           Loc = l.locations.Where(x => x.Name.StartsWith(term)).Select(x => x.Name).Distinct().ToList();
           return Json(Loc, JsonRequestBehavior.AllowGet);
       }
   }

View:

@model IEnumerable<SearchBox.Models.Locations>
@using SearchBox.Models
@{
    ViewBag.Title = "Index";
}
<link href="~/Content/jquery-ui.css" rel="stylesheet" />
<script src="~/Content/jquery-ui.js"></script>
    <script type="text/javascript">
    $(function () {
        $('#searchText').autocomplete({
            source: '@Url.Action("Search")' 
            });
    })
</script>
 

 
<h2>Search Demo</h2>
@using (Html.BeginForm())
{
   <input type = "text" id="searchText" name="searchText" />
   <input type="submit" value="Search" />
}
