Answer 1

我会用PDFSharp： http ：//pdfsharp.com/PDFsharp/index.php？option = com_content＆task = view＆id = 52＆Itemid = 45

Answer 2

This doesn't use C#, but the way I typically do this is to use ghostscript:

gs -q -sPAPERSIZE=letter -dNOPAUSE -dBATCH -sDEVICE=pdfwrite -sOutputFile=out.pdf in1.pdf in2.pdf in3.pdf ...

Basically, this prints out several pdfs in sequence, but redirects the output to a output pdf, effectively concatenating them.

Disclaimer: I work at Atalasoft. Our DotImage Document Imaging SDK can do this. Here's a whitepaper with all of the code you need .

It's simply:

PdfDocument.Combine("FinalReport.pdf", "CoverSheet.pdf";,
                                   "Disclaimer.pdf", "Report.pdf");
