1、单一产品情况下使用：

public ActionResult GetStockList(){    var item = _db.Stocks.ToList().Select(s =>s.Product.CodePro);    return Json(item, JsonRequestBehavior.AllowGet);}

     
     
      Tags:      
      
     

 2、多组返回值的情况下：

     
    
      
      
        Find by name: @Html.TextBox("SearchString")           
       
     

public ActionResult AutocompleteSuggestions(string term){  var suggestions = db.Students.Select(s => new { label = s.LastName+"|"+s.FirstMidName, value = s.StudentID}).Where(b=>b.label.ToLower().StartsWith(term.ToLower()));  return Json(suggestions, JsonRequestBehavior.AllowGet);}
