I have a PDF file which I need to fill out through a form made in visual basic .net, I have read it with the iTextSharp library, however I do not know how to write in the existing PDF through code.

Some time ago I did something similar, unfortunately I do not have the code but I can leave the link with the article with which I guide link
Basically you have to create your PDF form assign the names of the fields, then as you explain in the article you fill them using
pdfFormFields.SetField("f1_01(0)", "1")
Where f1_01 (0) is the name of your field in the PDF
To create the PDF form I use adobe acrobat, but I understand that it is also possible with Oppen Office
