Aspose.Note cannot read OneNote.Online document changed with Aspose.Note

Hi Aspose team,

my scenario is:

  • create OneNote document in SharePoint.Online which has hyperlink
  • using Aspose.Note make change of hyperlinks from, for example, to
  • save document
  • open document via OneNote.Online (just open it by click in SharePoint)
  • close document
  • using same code try to make second change => this does not work as Aspose.Note cannot open document anymore. Error message is:

Problem to open document (error: Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index)

In attachment you can find:

  • Prep.mp4 => video how to create OneNote file
  • Result.mp4 => video showing that change of hyperlink is done and then error message in Notepad
  • VStudioScreenShot.jpg => screenshot with error from VS
  • Error Message.txt => error message and stack
  • SourceCode.txt => function used to make change. Unfortunately, we cannot share source code to connect to the SharePoint as this is part of huge project but, at least, in function you can see how is change done.

If same code is used against locally saved OneNote documents created with OneNote 2016 using same process there is no problem to read document with Aspose.Note after document is changed with Aspose.note and then opened by OneNote 2016.

In case of anything please let me know.

Hi Amjad,

please find attached OneNote document before change (working) and after change (not working).
Process was:

  • Connect to the SharePoint
  • Open OneNote document with my app based on latest version of Aspose.Note components
  • Search for and replace with
  • Open document directly via SharePoint and close it
  • Try to open document with Aspose.Note and then got error: Problem to open document (error: Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index)

Hi Aspose team,

any chance to get prerelease version for our testing?



Generally, we do not provide interim fixes in the forum for Aspose.Note for .NET. I guess you may consider purchasing Paid support to get the quick fix.
