  Word Document Corrupted After Posting to Controller

  Dec 10, 2019 09:13 PM|madaxe|LINK

  Evening,

  I appreciate everybody input and patience this is my third week learning C# and ASP, so still a green horn, but I'm learning.

  So i can post the file and save the file but when i open the file in word it tells me that it is Word Found Unreadable Content do you want to recover the file Yes, No.

  I've trawled the internet and found a few solutions I have focused on these two but I'm still stuck any help would be awesome.

  Thanks

  Madaxe

  byte[] HttpPostedDocumentFileData = new byte[HttpPostedDocumentFile.InputStream.Length];
  File.WriteAllBytes(Path.Combine(path, VaultFileName), HttpPostedDocumentFileData);
  
  //Method2

  How are you currently uploading the documents?  Are you using HTTP multipart form?  

  I would use HttpClient and you can include the file name in the HTTP message.

  Thanks for the response here is the client side code for the word addin

  public static Boolean StreamFileToVault(string iURL, Document iDocument)
          {
              LogHelper.Log(LogTarget.File, LogSeverity.Information, "Start_StreamFileToVault.");
              Boolean ReturnBoolean = false;
              try
              {
                  Dictionary<string, string> FileUploadDictionary = new Dictionary<string, string>();
                  FileUploadDictionary.Add("Document", iDocument.FullName);
                  FileUploadDictionary.Add("XMLFile", Path.Combine(iDocument.Path, Path.GetFileNameWithoutExtension(iDocument.FullName)) + ".xml");
  
                  using (HttpClient client = new HttpClient())
                  {
                      client.DefaultRequestHeaders.Accept.Clear();
                      client.BaseAddress = new Uri(WordAddinImplementation._BaseAddress);

                          {
                              WordAddinImplementation.AddFileContent(iItem.Key.ToString(), FileUploadDictionary[iItem.Key], content);
                          }
  
                          HttpResponseMessage response = client.PostAsync(iURL, content).Result;
  
                          if (response.StatusCode == System.Net.HttpStatusCode.OK)

                  LogHelper.Log(LogTarget.File, LogSeverity.Information, "End_StreamFileToVault.");
              }
              catch (Exception ex)
              {
                  throw new Exception("Webservice Failed to Stream File to Vault", ex);
              }
              return ReturnBoolean;
          }

  private static void AddFileContent(string iKey,string iFilePath, MultipartFormDataContent iContent)
          {
              FileStream DocFileStream = new FileStream(iFilePath, FileMode.Open, FileAccess.Read, FileShare.ReadWrite);
  
              byte[] Bytes = new byte[DocFileStream.Length + 1];
              DocFileStream.Read(Bytes, 0, Bytes.Length);
  
              //"application/vnd.openxmlformats-officedocument.wordprocessingml.document";
  
              ByteArrayContent fileContent = new ByteArrayContent(Bytes);
              fileContent.Headers.ContentDisposition = new ContentDispositionHeaderValue("attachment") { FileName = iKey };

  Hi madaxe,

  According to your description, please confirm whether the word document can be successfully opened before you upload it?

  Usually when a word file becomes corrupted and its contents become unreadable, you may encounter the "Word found unreadable content" issue.

  You can refer to this for more information : Word found unreadable content...

  Is HttpPostedDocumentFile your custom class in your code?

  I cannot successfully test your code because your code does not provide comprehensive information, but you can refer to this link to try to change the way to save the file:

  https://stackoverflow.com/a/37291210

  Upload files in ASP.NET Core

  Best Regards,

  YongQing.
