  string fileNameExisting = @"C:\Biddocument.pdf";

  string fileNameNew = @"C:\new.pdf";

   using (var existingFileStream = new FileStream(fileNameExisting, FileMode.Open))           

  using (var newFileStream = new FileStream(fileNameNew, FileMode.Create)) 

            {         

        var pdfReader = new PdfReader(existingFileStream);
        PdfStamper pdfStamper = new  PdfStamper(pdfReader,newFileStream);               

  pdfStamper.FormFlattening = true; // generate a flat PDF

  if you want to find a string in a string, then there are many ways, you can use String.Replace() or else you can sue Regex to find the match and then replace...

  PS - if you question is related to specifically about ITextSharp please post your question in their forums...

  Thanks,
