            public IActionResult Upload()
            {
                return View();
            }

            [HttpPost]
            public async Task<IActionResult> Upload(Document document, IFormFile upload)
            {
                if (!ModelState.IsValid)
                {
                    return View(document);
                }

                if (upload != null)
                {
                    var filePath = Path.Combine("RLPDocumentUpload/Uploads", upload.FileName);

                    using (var stream = new FileStream(filePath, FileMode.Create))
                    {
                        await upload.CopyToAsync(stream);
                    }

                    document.FilePath = filePath;
                    ViewBag.SuccessMessage = "Upload Successful";
                }

                // Handle other logic here

                return View(document);
            }
        }
    }

您不需要“ uploadDocumentModel.cs”，即“ razorpages”模式。提交应将文件发布给控制器。根据控制器端点

public async Task<IActionResult> Upload(Document document, IFormFile upload)

，
