我正在使用以下代码将图像文件上传到 SharePoint 文档库。该代码在本地运行良好，但一旦部署到服务器，我就会收到异常，因为找不到文件。

                String fileToUpload = FlUpldImage.PostedFile.FileName; //@"C:\Users\admin.RSS\Desktop\Photos\me_skype.jpg";
                String documentLibraryName = "SiteAssets";
                if (!System.IO.File.Exists(fileToUpload))
                    throw new FileNotFoundException("File not found.", fileToUpload);

                SPFolder myLibrary = web.Folders[documentLibraryName];

                // Prepare to upload
                Boolean replaceExistingFiles = true;
                String fileName = CheckStringNull(txtFirstName.Text) + CheckStringNull(txtLastName.Text) + CheckDateNull(txtDOB) + System.IO.Path.GetFileName(fileToUpload); ;
                if (fileName.Contains('/'))
                {
                    fileName = fileName.Replace("/", "");
                }
                if (fileName.Contains(':'))
                {
                    fileName = fileName.Replace(":", "");
                }
                FileStream fileStream = File.OpenRead(fileToUpload);
                //Upload document
                SPFile spfile = myLibrary.Files.Add(fileName, fileStream, replaceExistingFiles);
                string url = site.ToString() + "/" + spfile.ToString();
                if (url.Contains("="))
                {
                    url = url.Split('=')[1];
                }
                //Commit
                myLibrary.Update();

字符串 fileupload 包含 URL，因为C:\Users\admin.RSS\Desktop\Photos\me.jpg这个 URL 实际上是客户端系统，服务器端代码抛出异常，因为找不到文件。如何处理这个问题？

更新：

我删除了检查文件是否存在的代码行，现在我得到了FileStream fileStream = File.OpenRead(fileToUpload);例外c:\windows\system32\inetsrv\20120605_133145.jpg cold not be found

请帮忙。谢谢你

            }
        }

将文件物理地保存到服务器上，而不是在服务器上工作，这帮助我解决了我的问题。
