de Răzvan Panda J'ai regardé le trafic. Il revient 200 ok. Le problème semble être avec javascrt comme il est dit pour activer javascript. – Newbie
Oui, vous aurez des problèmes si les parties de la page que vous voulez sont rendus en utilisant Javascript, car ils ne seront pas disponibles si vous faites juste un WebClient.DownloadString(). Dans ce cas, vous avez besoin d'un moteur pour rendre le Javascript. Une façon est d'utiliser le contrôle Webbrowser, donc il rend le JavaScript, puis vous pouvez accéder au code HTML après que le Javascript a fait son travail. – Kelly
