Answer 1

Following method merges two pdfs( f1 and f2) using iTextSharp. The second pdf is appended after a specific index of f1.

 string f1 = "D:\\a.pdf";
 string f2 = "D:\\Iso.pdf";
 string outfile = "D:\\c.pdf";
 appendPagesFromPdf(f1, f2, outfile, 3);




  public static void appendPagesFromPdf(String f1,string f2, String destinationFile, int startingindex)
        {
            PdfReader p1 = new PdfReader(f1);
            PdfReader p2 = new PdfReader(f2);
            int l1 = p1.NumberOfPages, l2 = p2.NumberOfPages;


            //Create our destination file
            using (FileStream fs = new FileStream(destinationFile, FileMode.Create, FileAccess.Write, FileShare.None))
            {
                Document doc = new Document();

                PdfWriter w = PdfWriter.GetInstance(doc, fs);
                doc.Open();
                for (int page = 1; page <= startingindex; page++)
                {
                    doc.NewPage();
                    w.DirectContent.AddTemplate(w.GetImportedPage(p1, page), 0, 0);
                    //Used to pull individual pages from our source

                }//  copied pages from first pdf till startingIndex
                for (int i = 1; i <= l2;i++)
                {
                    doc.NewPage();
                    w.DirectContent.AddTemplate(w.GetImportedPage(p2, i), 0, 0);
                }// merges second pdf after startingIndex
                for (int i = startingindex+1; i <= l1;i++)
                {
                    doc.NewPage();
                    w.DirectContent.AddTemplate(w.GetImportedPage(p1, i), 0, 0);
                }// continuing from where we left in pdf1 

                doc.Close();
                p1.Close();
                p2.Close();

            }
        }
