Error while merging two PDFs.

Question

We are using Winnovative PDF Merge for .NET Original version. While we merge two PDF files, the below error is coming:

Error 1 An unhandled exception of type 'System.StackOverflowException' occurred in mscorlib.dll Wrror 2 Could not append pdf file 'E:\WWWROOT\DRB_Webservice\Upload_Document\44e0a692-1343-4e2f-8e12-a7f3ef1c6f1f.pdf'. The PDF objects nesting level is too high.

Answer 1

This indicates that the level of the objects contained within the PDF files is too big. I have seen some tutorials regarding the nesting procedure, and it seemed that many users tried to merge complicated PDFs. I recommend re-structuring the PDF file to make it as simple as possible. Avoid using complicated links and objects grouping then the application should work normally.
