how to Add Input Text Field to Pdf (AcroForm) with PDFSharp

问题

it's should be simple but i couldn't find the answer anywhere in google or the source documentation.

someone have asked the same question 4 years ago, but still no one answered!

if it's not possible. can someone please confirm, so that i can find another pdf generator library that can do that. because it's very important in my case to be able to generate pdf with input capability

thanks!

We will go through the step by step

1. First you need to create object of PdfReader
   • PdfReader pdfReader = new PdfReader(templatePath); here "templatePath" is the template(sample file) where you write your all data
2. Then create source file where all data is rendered(write)
   • System.IO.Directory.CreateDirectory(Server.MapPath(DocPath)); "DocPath" is the path where output file is save

3. Then Initialize PdfStamper and AcroFields object :

   PdfStamper pdfStamper = new PdfStamper(pdfReader, new FileStream(Server.MapPath(newFile), FileMode.Create));
   AcroFields pdfFormFields = pdfStamper.AcroFields;
   

4. Then set Field in PDF :

       pdfFormFields.SetField("this text should field name in PDF(template PDF)", "Actual value you want to write");
   

5. Dispose all objects

       pdfStamper.FormFlattening = true;
       pdfStamper.Close();
       pdfReader.Close();
