How do I add page hyperlink on PDF using PDFNet SDK?

Q: Is it possible to create a pdf that if clicked on (anywhere on
the document), it can follow a link to a webpage? I’m not referring to
internal or external links in a document, but the entire document
(actual link is not visible).
A: You can create a link annotation (along the lines of the
Annotation sample project) that covers the entire page.
You could use:

Action a = pdftron.PDF.Action.CreateURI(doc, "");
pdftron.PDF.Annots.Link link = pdftron.PDF.Annots.Link.Create(doc,
page.GetCropBox(), a);
