Extract Form Fields from PDF document using Aspose.PDF in C# - All forms fields are not being identified

Aspose.PDF Product Family
1

All form fields are not identified from the pdf, I can share the pdf that I am using in a private email, not sure whether I can share the pdf in public forum as it is related to insurance industry.
we use currently iTextSharp on production.
//iTextSharp code to get all the acrofields is below:

temppdfReader = new PdfReader(pdfTemplate);
tempStamper = new PdfStamper(temppdfReader, new FileStream(pdfNew, FileMode.Create));

AcroFields fields = tempStamper.AcroFields;

Am trying same using aspose, but its retrieving only 4 out of 16 fields on the pdf.
Approach 1 using Aspose:

        var dataDir = GetDataDir_Data();
        var pdfDocument = new Document(dataDir + "sample-doc.pdf");
        return pdfDocument.Form.Fields;

As suggested on this forum I also tried below code:
Approach 2:
var dataDir = GetDataDir_Data();
var pdfDocument = new Document(dataDir + “sample-doc.pdf”);
pdfDocument.Form.XFA.FieldNames;

Approach 3:
fs = new FileStream(dataDir + “sample-doc.pdf”, FileMode.Open, FileAccess.Read, FileShare.ReadWrite);
var pdfDocument = new Document(fs);
formFields = pdfDocument.Form.XFA.FieldNames;

We have tested the scenario in our environment and did not notice any issue. The API was giving count of total 16 form fields:

using (var pdf = new Document(dataDir + "C-622-NJ.pdf"))
{
  // Approach 1
  var totalFields = pdf.Form.Fields.Length;
  // Approach 2
  var form = new Aspose.Pdf.Facades.Form(pdf);
  var count = form.FieldNames.Count();
}

It seems like you are using the API without any valid license. It is a trial version limitation that API can process only 4 elements of any collections e.g. Annotations, Paragraphs, Form Fields, etc. Would you please try using a 30-days free temporary license in order to use the API without any restriction. In case you still face any issue, please let us know.
