Response.Redirect geben HttpException Ausnahme

Question

Ich arbeite an der Erstellung von Web-Anwendung und ich bekomme Problem umleiten auf eine andere Seite, wenn ich Redirect-Code in einer anderen Methode dann funktioniert es gut, aber ich möchte Redirect-Code aus meinem laufenden Thread und verwenden es wirft mich HttpExeption.Please können Sie einen Blick auf diesen Code und zeigen richtigen Weg zur Verwendung von Redirect-Code in meinem Runloop() -Methode.Vielen Dank im Voraus.

Sie versuchen das Reponse Objekt von einem Hintergrund-Thread zuzugreifen, wo die Antwort schon lange vorbei.

Sie können nicht auf das Objekt Response oder auf ein anderes Objekt unter HttpContext zugreifen, nachdem die Wiedergabe der Seite beendet wurde. Verwenden Sie Web-Sockets oder AJAX-Aufrufe, um asynchrone Anforderungen und Antworten zu erstellen.
