c# Word-AddIn convert activeDocument to a virtual PDF and merge them into one PDF document

Question

I am creating multiple virtual documents and then I want to merge them into one PDF, without saving them somewhere. All I found for now are guides, in which they save the document as a PDF somewhere and then they read the PDF to merge them into one.

It should also be possible to combine multiple PDFs and not only two.

Answer 1

Why don't you want to save them somewhere? You could create temporary files at a place like C:\\Users\\%username%\\AppData\\Local\\Temp\\%yourProject% , work with those files, following the guide you've found and clean up afterwards. At least I don't see a problem with using temporary files and folders at the right place.
