Question

您好我正在使用asp.net mvc5上传一个大文件到服务器和控制器我将此流保存到TempData.on我的本地机器它工作正常并成功上传大文件。但在托管服务器上它fails.i已经尝试过增加MaxAllowedContent和ExcutionTimeOut Limit但没有一个工作。任何人都可以帮助我。

这是我的控制器动作

 public ActionResult UploadTransactionPDF()
        {
        private readonly List<MemoryStream> _PdfImage = new List<MemoryStream>();

        private readonly List<string> _PdfImageNames = new List<string>();
            try
            {
                Gateway.Instance.Logger.LogInfo(string.Format(_formatProvider,"[TransactionController  -> UploadTransactionPDF ]: method started : Save pdf to memory."));

                if (CheckFileExist())
                {
                    if (TempData[TransactionRef.PdfFiles.ToString()] != null)
                    {
                        _PdfImage.Clear();
                        _PdfImage.AddRange(TempData[TransactionRef.PdfFiles.ToString()] as List<MemoryStream>);
                    }

                    if (TempData[TransactionRef.PdfFileName.ToString()] != null && !string.IsNullOrEmpty(TempData[TransactionRef.PdfFileName.ToString()].ToString()))
                    {
                        _PdfImageNames.Clear();
                        _PdfImageNames.AddRange(TempData[TransactionRef.PdfFileName.ToString()] as List<string>);
                    }

                    for (int a = 0; a < Request.Files.Count; a++)
                    {
                        if (!_PdfImageNames.Contains(Request.Files[a].FileName))
                        {
                            MemoryStream ms = new MemoryStream();
                            Request.Files[a].InputStream.CopyTo(ms);
                            _PdfImage.Add(ms);
                            _PdfImageNames.Add(Request.Files[a].FileName);
                        }
                    }

                    TempData[TransactionRef.PdfFiles.ToString()] = _PdfImage;
                    TempData[TransactionRef.PdfFileName.ToString()] = _PdfImageNames;
                    ViewBag.Info = "pdf";
                    ViewBag.ImageUploadInfo = Language.ImageSavedMessage.ToString();
                }
                else
                {
                    ViewBag.ImageUploadInfo = Language.NoFileMessage.ToString();
                }

                ViewBag.FileNames = _PdfImageNames;
                Gateway.Instance.Logger.LogInfo(string.Format(_formatProvider, "[TransactionController  -> UploadTransactionPDF ] : method exited ."));
                return View("_PDFFiles");
            }
            catch (Exception ex)
            {
                string errorInfo = string.Format(_formatProvider, "[TransactionController  -> UploadTransactionPDF ]  : Error : '{0}' occurred while saving pdf to memory.",ex.Message);
                Gateway.Instance.Logger.LogError(errorInfo,ex);
                throw new Exception(errorInfo, ex);
            }
        }

谢谢！

您可以查看开发环境中的web.config与服务器上是否存在以下内容。 ddddd应该是您的请求应允许的最大值。不要把它打到你打开DOS的地方。请求长度不仅仅是文件大小，而是从客户端到服务器的整个请求。

<configuration>
  <system.web>
    <httpRuntime targetFramework="4.5" maxRequestLength="ddddd" />
  </system.web>
</configuration>

您可以通过在配置和system.web元素之间添加位置元素，将其本地化为一个控制器操作。
