In your code after pdfDoc.Close() statement paste this code:
It Will Add Header as well as page numbers at bottom

// add page numbers
          Document copyDoc = new Document();
          PdfCopy copyPdf = new PdfCopy(copyDoc, new FileStream(filepath, FileMode.Create));
          copyPdf.SetPageSize(PageSize.A4.Rotate());
          copyDoc.Open();
          Font textFont = FontFactory.GetFont("Helvetica", 9, Font.NORMAL, BaseColor.BLACK);
          Font headerFont = FontFactory.GetFont("Helvetica", 12, Font.BOLD, BaseColor.BLACK);
          // read the initial pdf document
          PdfReader reader = new PdfReader(pdfStream.ToArray());
          int totalPages = reader.NumberOfPages;

          PdfImportedPage copiedPage = null;
          iTextSharp.text.pdf.PdfCopy.PageStamp stamper = null;

          for (int i = 0; i < totalPages; i++)
          {
              // get the page and create a stamper for that page
              copiedPage = copyPdf.GetImportedPage(reader, (i + 1));
              stamper = copyPdf.CreatePageStamp(copiedPage);

              // add a page number to the page
              //ColumnText.ShowTextAligned(stamper.GetUnderContent(), Element.ALIGN_CENTER, new Phrase((i + 1) + "/" + totalPages, textFont), 820f, 15, 0);
              ColumnText.ShowTextAligned(stamper.GetUnderContent(), Element.ALIGN_CENTER, new Phrase(String.Format("Page {0} of {1}", i + 1, reader.NumberOfPages)), 300f, 40, 0);
              ColumnText.ShowTextAligned(stamper.GetOverContent(), Element.ALIGN_CENTER, new Phrase("your page heading name", headerFont), 300f, 780, 0);

              stamper.AlterContents();

              // add the altered page to the new document
              copyPdf.AddPage(copiedPage);
          }

          copyDoc.Close();
          reader.Close();

          // flush and clear the document from memory
          pdfStream.Flush();
          pdfStream.Close();

Hi Hari,

You could try this :

C#

private void addHeader(pdf iPdf)
         {
             try
             {
                 iPdf.addCell("US President", 14, 1, 3, 0);
                 iPdf.addCell("Wars started", 3);
                 iPdf.addCell("Body count", 3);
                 iPdf.addCell("Weapons used(WMD)", 3);
             }
             catch (Exception ex)
             {
                 lblErrMessage.Text = ex.Message;
             }
         }

Please note :

For iTextSharp version 5+, Header/Footer property has been removed. Now this can be done by us PageEventHandler class. Though it's not straight forward now but the upside is that now you can add more than just plan text in header and footer.

Please check the following links :
