Je commenté la section CustomErrors dans system.web

Et dans mes FilterConfig.cs I ont:

public class FilterConfig 
{ 
    public static void RegisterGlobalFilters(GlobalFilterCollection filters) 
    { 
     filters.Add(new HandleErrorAttribute()); 
    } 
} 

Voici mon fichier page400.html:

<!DOCTYPE html> 
<html xmlns="http://www.w3.org/1999/xhtml"> 
<head> 
    <title></title> 
</head> 
<body> 
    <h1>Page is not there dude !!</h1> 
    Sorry about this. 
</body> 
</html> 

sous le dossier d'erreur. Mais encore quand je frappe

http://localhost:49376/private/aaa 

(aaa méthode d'action n'est pas là) au lieu de la page d'erreur personnalisée, il me donne toujours la page d'erreur traditionnelle.

Voici ma capture d'écran Version IIS:

Mise à jour:

Je sais que la question semble un double d'un existant. Mais les réponses données ici ne résolvent pas mon problème. Je n'arrive toujours pas à voir la page d'erreur personnalisée 404.

Answer 1

Utiliser la configuration du serveur Web:

<system.webServer> 
    <httpErrors errorMode="Custom" existingResponse="Replace"> 
     <remove statusCode="404" /> 
     <error 
     statusCode="404" 
     path="/Error/page404.html" 
     responseMode="ExecuteURL" /> 
    </httpErrors> 
</system.webServer> 

Et ajoutez cette ligne à la méthode RegisterRoutes sur RouteConfig css:

routes.IgnoreRoute("Error/page404.html");
