I fill these fields by using following code(itextsharp).

 DataTable dt = new DataTable();
                  


        

Answer 1

Your code line

stamper.FormFlattening = true;

instructs iTextSharp to flatten the form fields, i.e. to integrate them into the page content and remove the form field annotations.

As you want to keep the form fields as editable fields, don't flatten the form.

Error: Cannot convert type in PDFHelper.cs

public static Dictionary<string, string> GetFormFieldNames(string pdfPath)
    {
        var fields = new Dictionary<string, string>();

        var reader = new PdfReader(pdfPath);
        foreach (DictionaryEntry entry in reader.AcroFields.Fields) //ERROR: 'System.Collections.Generic.KeyValuePair' to 'System.Collections.DictionaryEntry'
        {
            fields.Add(entry.Key.ToString(), string.Empty);
        }
        reader.Close();

        return fields;
    }

'System.Collections.Generic.KeyValuePair' to 'System.Collections.DictionaryEntry'
