i'm trying create xps file out of documentviewer:

microsoft.win32.savefiledialog dlg = new microsoft.win32.savefiledialog(); dlg.filename = "myreport"; // default file name dlg.defaultext = ".xps"; // default file extension dlg.filter = "xps documents (.xps)|*.xps"; // filter files extension  // show save file dialog box nullable<bool> result = dlg.showdialog();  // process save file dialog box results if (result == true) {     // save document     string filename = dlg.filename;      fixeddocument doc = (fixeddocument)documentviewer.document;     xpsdocument xpsd = new xpsdocument(filename, fileaccess.readwrite);     system.windows.xps.xpsdocumentwriter xw = xpsdocument.createxpsdocumentwriter(xpsd);     xw.write(doc);     xpsd.close(); }

but throws following exception in xw.write(doc):
