Answer 1

Have a look at iTextSharp. iTextSharp is a port of the iText , a free Java-Pdf library.

To quote iText:

You can use iText to:

• Serve PDF to a browser
• Generate dynamic documents from XML files or databases
• Use PDF's many interactive features
• Add bookmarks, page numbers, watermarks, etc.
• Split, concatenate, and manipulate PDF pages
• Automate filling out of PDF forms
• Add digital signatures to a PDF file
• And much more...

Syncfusion Essential PDF is the best. I have been using it for years. Also, Syncfusion provides a best support compared to other vendors.
