سلام  
در کد زیر میخواهم اطلاعات را ارسال کنم برای Create ولی میره سراغ اکشن Get به جای Post

//------------< jQuery - script > ------------
    $(document).ready(function () {

        $("#upload").click(function (evt) {
            var data = new FormData();
            var files = $("#STicket_Files").get(0).files;

            var isvalid = $("#Form_Id").valid();  // Tells whether the form is valid

            if (isvalid === false)
                return false;
            else {

                data.append("STicket_Files", files[0]);
                data.append("STicket_Text", $("#STicket_Text").val());
                data.append("Ticket_Id", $("#Ticket_Id").val());

                $.ajax({

                   
                    type: "POST",

                    url: "/TicketDetails/Create",

                    contentType: false,

                    processData: false,

                    data: { viewModel:data },

                    success: function (data) {

                        swal({

                            type: 'success',
                            title: "بارگداری فایل ",
                            text: "فایل با موفقیت بارگذاری شد",
                            showConfirmButton: true,
                            confirmButtonText: "تائید",
                        })

                    },

                    error: function (e) {
                        swal("خطا", "خطلا در ارسال اطلاعات دوباره سعی کنید", "error");
                    }

                });
            }

        });

    });

Controller

  [HttpGet]
        // GET: TicketDetails/Create
        public async Task<IActionResult>Create(int id)
        {
            var ticketMaster = await _genericRepository_TicketMaster.GetByIdIncludesAsync(m => m.Ticket_Id == id, "TicketMaster");
            ViewData["Ticket_Id"] = ticketMaster.Ticket_Id;
            ViewData["Ticket_Title"] = ticketMaster.Ticket_Title;

            return View();
        }

        [HttpPost]
        [ValidateAntiForgeryToken]
        public async Task<IActionResult> Create(TicketDetailsViewModel viewModel)
        {
            //if (ModelState.IsValid)
            //{
            //    _genericRepository.Add(ticketDetails);
            //    await _genericRepository.SaveChangesAsync();
            //    return RedirectToAction(nameof(Index));
            //}
            //ViewData["Ticket_Id"] = new SelectList(await _genericRepository_TicketMaster.GetAllAsync(), "Ticket_Id", "Ticket_CreateDate", ticketDetails.Ticket_Id);
            return View(viewModel);
        }
