What I have tried:

here is my controller code ...

C#

[HttpPost]
        public ActionResult Create(FormCollection collection,string command,List<Orderdetail> Values)
        {
            try

                //if (ModelState.IsValid)
                //{ 
               
                            List<FILEDETAIL> FILEDETAILs = new List<FILEDETAIL>();
                            for (int i = 0; i < Request.Files.Count; i++)

                                var file = Request.Files[i];
                                if (file != null && file.ContentLength > 0)

                                }                               
                            }

                            List<REQ_ITEM_DETAILS> reqitem = new List<REQ_ITEM_DETAILS>();
