Thanks for you reply.
Do you have any idea which .Net Library is available for this functionality.
I found the below code in internet . It is using iText Library which we will have to buy i guess as its not already included in .Net libraries.
Is this the right direction i am looking my solution in ?
using iText.Forms;
using iText.Kernel.Pdf;
using iText.Pdfa;
using iText.Layout.Element;
using System;
using System.Collections.Generic;
using System.IO;
using System.IO.Compression;
using System.Linq;
using System.Text;
namespace PdfXml
{
class Program
{
static void Main(string[] args)
{
string pdfIn = "\\xfar\\pdfin.pdf";
string pdfOut = "\\xfar\\pdfoutU.pdf";
string cdaIn = "\\xfar\\cda.xml";
StreamReader Reader = new StreamReader(cdaIn);
var content = new StringBuilder();
string line;
while (Reader.EndOfStream == false)
{
line = Reader.ReadLine();
content.AppendLine(line);
}
byte[] bytes = Encoding.ASCII.GetBytes(content.ToString());
PdfDocument pdfDoc = new PdfDocument(new PdfReader(pdfIn), new PdfWriter(pdfOut));
PdfStream stream = new PdfStream();;
PdfNameTree nameTree1 = pdfDoc.GetCatalog().GetNameTree(new PdfName("XFAResource"));
stream.SetCompressionLevel(9);
stream.SetData(bytes, true);
nameTree1.AddEntry("dataset", stream);
nameTree1.BuildTree();
nameTree1.SetModified();
Console.WriteLine("ok");
}
pdfDoc.Close();
}
}
}
