can me on this?

create new page events class:

public class pageevents : pdfpageeventhelper      {                public override void onstartpage(pdfwriter writer, document document)          {              base.onstartpage(writer, document);                document.add(...header...);          }      } 

and in codes:

   class program      {          static void main(string[] args)          {              using (var pdfdoc = new document(...))              {                  var pdfwriter = pdfwriter.getinstance(pdfdoc, new filestream("test.pdf", filemode.create));                  pdfwriter.pageevent = new pageevents();                  ....
