Question

所以我在我的控制器中有动作方法，它从我通过网络上传的CSV文件中获取数据

我想将该数据传递给Insert控制器，以便CSV中的数据自动插入到我的数据库中的表中并将其传递给视图

我使用的是CSV HELPER，MVC

        public ActionResult ImportCSV(HttpPostedFileBase file, int compID)
        {
            var compName = db.CourierCompanies.Find(compID);

            string path = null;

            List<MyViewModel> csvD = new List<MyViewModel>();

            try
            {
                if(file.ContentLength > 0)
                {
                    var fileName = Path.GetFileName(file.FileName);
                    path = AppDomain.CurrentDomain.BaseDirectory + "upload\\" + fileName;
                    file.SaveAs(path);

                    var csv = new CsvReader(new StreamReader(path));
                    var invoCSV = csv.GetRecords<ImportCsV>();

                    foreach(var i in invoCSV)
                    {
                        MyViewModel iCSV = new MyViewModel();

                        iCSV.CustID = i.cust_id;
                        iCSV.Fullname = i.fullname;
                        iCSV.CustComp = i.company;
                        iCSV.InvoiceNo = i.rec_no;
                        iCSV.InsertDate = DateTime.Parse(i.doc_dt);
                        iCSV.Road = i.w_addr1;
                        iCSV.City = i.w_city;
                        iCSV.Zip = i.w_zip;
                        iCSV.Phone = i.w_phone;
                        iCSV.Status = "BelumTerkirim";
                        iCSV.compID = compID;
                        iCSV.CompName = compName.CompName;
                        iCSV.StatDate = DateTime.Now;

                        csvD.Add(iCSV);
                    }
                }
            }
            catch
            {
                ViewData["Error"] = "Upload Failed";
            }

            return View();
        }

插入控制器

public ActionResult Create( MyViewModel model, int compID, HttpPostedFileBase file)
        {
            if (file != null)
            {
                using (MemoryStream ms = new MemoryStream())
                {
                    file.InputStream.CopyTo(ms);
                    model.Image = ms.GetBuffer();
                }
            }

            var cust = new Customer()
            {
                CustID = model.CustID,
                Phone = model.Phone,
                CustComp = model.CustComp,
                Fullname = model.Fullname
            };

            var addrDet = new AddrDetail()
            {
                Road = model.Road,
                City = model.City,
                Zipcode = model.Zip
            };

            var invoice = new Invoice()
            {
                InvoiceNo = model.InvoiceNo
            };

            var stat = new Status()
            {
                Status1 = model.Status,
                StatDate = model.StatDate,
                Ket = model.Ket
            };

            var image = new Models.Image()
            {
                Image1 = model.Image
            };

            var detail = new DetailPengiriman()
            {
                NamaPenerima = model.NamaPenerima,
                StatusPenerima = model.StatusPenerima,
                TrDate = model.TrDate,
                InsertDate = model.InsertDate
            };

            if (ModelState.IsValid )
            {
                //customer
                db.Customers.Add(cust);
                detail.CustID = cust.CustID;
                invoice.CustID = cust.CustID;

                //addrDet
                db.AddrDetails.Add(addrDet);
                cust.AddrDetID = addrDet.AddrDetID;

                //invoice
                db.Invoices.Add(invoice);
                stat.InvoiceNo = invoice.InvoiceNo;
                image.InvoiceNo = invoice.InvoiceNo;
                detail.InvoiceNo = invoice.InvoiceNo;

                //status
                db.Status.Add(stat);
                detail.StatusID = stat.StatusID;

                ////image
                db.Images.Add(image);
                detail.ImageID = image.ImageID;

                //detail
                detail.CompID = compID;
                db.DetailPengirimen.Add(detail);

                db.SaveChanges();

                return RedirectToAction("Index", new { compID = detail.CompID});
            }
            return View();
        }

Answer 1

您可以在另一个类中抽象该业务逻辑，并在CSV操作中实例化它。

通过这种方式，您可以调用方法从两个操作中插入客户！

将数据列表传递给其他控制器
