Thanks Bruno, this looks like it should work,
However, I repeatedly get the error "Specified cast is not valid" on document.Close() when using the example (adapted for .NET). I am using the PDF files from the example, and creating a new output file each time.
I have tried flushing the writer, and creating the FileStream outside of the PdfCopy method in order to flush and close it properly also; but the same error occurs, and the file, although created, is corrupted and cannot be repaired or opened.
I don't understand what is being cast. Am I using the correct Stream type?
(code attached)
thanks,
Mark

If you're using C#, then you should download a .NET port of iText,
for instance: http://itextsharp.sourceforge.net/
From there it's easy to adapt the examples in the iText tutorial:
