stream mystream; savefiledialog savefiledialog1 = new savefiledialog();          savefiledialog1.filter = "pdf files (*.pdf)|*.pdf|all files (*.*)|*.*";         savefiledialog1.filterindex = 0;         savefiledialog1.restoredirectory = true;          if (savefiledialog1.showdialog() == dialogresult.ok)         {             if ((mystream = savefiledialog1.openfile()) != null)             {                 // code write stream goes here.                 pdfwriter.getinstance(pdfdoc, mystream);                 mystream.close();  using (filestream file = new filestream(savefiledialog1.filename, filemode.create, system.io.fileaccess.write,fileshare.readwrite)) {    byte[] bytes = new byte[mystream.length];    ms.read(bytes, 0, (int)mystream.length);    file.write(bytes, 0, bytes.length);    mystream.close(); }              }         }

you can write stream data using streamwriter...
