I’m by no means a good programmer (and know zilch about C#) and I read this
list to learn more about PDF and iText issues/usages but it seems to my humble
mind (not fishing for compliments here BTW) that you open many files within the
while loop (pdfDoc.Open()) but close them only once outside the loop. So to the
unsuspecting it look as if you close only the last file opened.
What I would try is moving the close inside the loop and keep my fingers
crossed. But I have been wrong (too many times …)

Betreff: [iText-questions] Merge PDF File release
Thank You for the quick response.
I have changed the code to the following
I am now using pdfCopy.
I still have the same error stating I can not delete the original pdf files
because they are in use.
Any help would be greatly appreciated.
Thanks,
Todd

Yes, you close the document but I don't see you closing any of the
PdfReaders or the PdfWriter, neither explicitely nor implicitely (e.g. by
utilizing a using statement). iText in the latest 10...15 releases more and
more stopped to do close calls itself as that disturbs some use cases, e.g.
when pages from a single document are imported in multiple other documents.
Furthermore your code is essentially merging source PDFs as is into a single
destination PDF. Using PdfWriter is not the optimal way to implement that;
if you used some Pdf*Copy* variant instead, you wouldn't have to deal with
all this page size and page orientation stuff, interactive features would be
copied, too, as good as possible, and the resulting PDF would internally be
better organized (not immediate a problem, but trouble might ensue if that
process is repeated multiple times).
You might want to read the (freely available) chapter 6 of iText in Action,
2nd edition, especially the later sections.
Regards, Michael
