c# - Render View in backend dll -

-

normally use this:

private byte[] getinvoiceaspdf(string id) {         var model = utilities.getmodel(id);         viewdata.model = model;          var view = viewengines.engines.findview(controllercontext, "pdflayout", null);         byte[] pdfbuf;         using (var writer = new stringwriter())         {             var context = new viewcontext(controllercontext, view.view, viewdata, tempdata, writer);             view.view.render(context, writer);             writer.flush();             string content = writer.tostring();             pdfbuf = utilities.converthtmltopdf(content);             if (pdfbuf == null)                 throw new exception("invalid pdfbuffer when creating pdf file.");         }         return pdfbuf; }

this works great when inside controller. need move dll file. how can convert , work inside dll file?

the problems controllercontext , viewdata/tempdata. in above set viewdata directly since inside controller , context controller.

it's still mvc project, logic moved dll file.

posting comment answer:

the solution pass necessary context information controller , other resources function parameters (or pass controller's instance if publicly exposes necessary contexts), , use them in function usual. way function have necessary information accomplish task.

i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
