How to read PDF form data using iTextSharp?

Question

I am trying to find out if it is possible to read PDF Form data (Forms filled in and saved with the form) using iTextSharp. How can I do this?

Answer 1

You would have to find out the field names in the PDF form. Get the fields and then read their value.

string pdfTemplate = "my.pdf";
PdfReader pdfReader = new PdfReader(pdfTemplate);
AcroFields fields = pdfReader.AcroFields.Fields;
string val = fields.GetField("fieldname");

Obviously in the code above, field name is the name of the PDF form field and the GetField method returns a string representation of that value. Here is an article with example code that you could probably use. It shows how you can both read and write form fields using iTextSharp.
