C # using the Itextsharp encapsulated PDF file Operation class Instance

This example describes the PDF file operation class that C # uses in Itextsharp encapsulation. Share to everyone for your reference. The specific analysis is as follows:

This C # code mainly itextsharp in the operation of the PDF file method has been re-encapsulated, more convenient to access the PDF document, you can dynamically generate PDF files, add content, set paragraphs, set fonts and so on.
