C＃MVC-上傳多個大文件以創建字節數組

Question

有人可以通過將大型文檔轉換為字節數組來幫助我上傳大型文檔（多個）嗎？

我的代碼當前沒有字節數組，但是如果文檔很大，它當然會失敗。

控制器：

[HttpPost] [ValidateAntiForgeryToken] public ActionResult Create（Invoice invoice）{if（ModelState.IsValid）{List fileDetails = new List（）; for（int i = 0; i <Request.Files.Count; i ++）{var file = Request.Files [i];

            if (file != null && file.ContentLength > 0)
            {
                var fileName = Path.GetFileName(file.FileName);
                FileDetail fileDetail = new FileDetail()
                {
                    FileName = fileName,
                    Extension = Path.GetExtension(fileName),
                    Id = Guid.NewGuid()
                };
                fileDetails.Add(fileDetail);

                var path = Path.Combine(Server.MapPath("~/App_Data/Upload/"),
                fileDetail.Id + fileDetail.Extension);
                file.SaveAs(path);

            }
        }

        invoice.FileDetails = fileDetails;
        db.Invoices.Add(invoice);
        db.SaveChanges();
        return RedirectToAction("Index");
    }
    return View(invoice);
}

和表單元素：

任何幫助都感激不盡。

排序！

[HttpPost] [ValidateAntiForgeryToken] public ActionResult Create（Invoice invoice）{if（ModelState.IsValid）{List fileDetails = new List（）;

            for (int i = 0; i < Request.Files.Count; i++)
            {
                HttpPostedFileBase httpPostedFileBase = Request.Files[i];

                if (httpPostedFileBase != null)
                {
                    Stream stream = httpPostedFileBase.InputStream;
                    BinaryReader bReader = new BinaryReader(stream);
                    byte[] bytes = bReader.ReadBytes((Int32)stream.Length);
                }

                HttpPostedFileBase postedFileBase = Request.Files[i];

                if (postedFileBase != null)
                {
                    var fileName = Path.GetFileName(postedFileBase.FileName);

                    FileDetail fileDetail = new FileDetail()
                    {
                        FileName = fileName,
                        Extension = Path.GetExtension(fileName),
                        Id = Guid.NewGuid()
                    };
                    fileDetails.Add(fileDetail);
                    //Save the Byte Array as File.
                    var path = Path.Combine(Server.MapPath("~/App_Data/Upload/"),
                        fileDetail.Id + fileDetail.Extension);
                    postedFileBase.SaveAs(path);
                    postedFileBase.InputStream.Flush();
                }
            }

            invoice.FileDetails = fileDetails;
            db.Invoices.Add(invoice);
            db.SaveChanges();
            return RedirectToAction("Index");
        }
        return View(invoice);
    }
