after editing pageevent, i'm still having issues. it's come mind i'm having issues calling pageevent , adding pdf (no experience itextsharp). below attempt add footer existing pdf has been passed byte[].

byte[] output = null; string identifier = id; string time = datetime.now.tostring(); string page = null;  pdfreader reader = new pdfreader(original); int n = reader.numberofpages;  try {    using (memorystream ms = new memorystream())    {       using (document doc = new document(pagesize.letter, 100, 100, 100, 100))       {          using (pdfwriter writer = pdfwriter.getinstance(doc, ms))          {             footerevent footer = new footerevent();              writer.pageevent = footer;              footer.footerfont = fontfactory.getfont(basefont.helvetica, 12, basecolor.black);              doc.open();              (int = 1; < n + 1; ++i)             {                doc.newpage();                page = "page " + + " of " + n;                footer.footerleft = identifier;                footer.footercenter = page;                footer.footerright = time;                 doc.add(new paragraph(reader.getpagecontent(i).tostring()));                //probably wrong. trying add contents each page in original pdf             }              doc.close();           }       }       output = ms.toarray();    } }  catch (exception ex) {    //some message added later }  return output;
