Exemples
L’exemple de code suivant crée un utilisateur pour une application ASP.NET configurée pour utiliser l’authentification par formulaire et l’appartenance ASP.NET. Si l’utilisateur n’est pas créé correctement, un message s’affiche à l’utilisateur. Si l’utilisateur est créé avec succès, il est redirigé vers la page de connexion de l’application. Cet exemple de code utilise l’énumération MembershipCreateStatus pour déterminer le message affiché à l’utilisateur en cas de défaillance.

Remarques
L’énumération MembershipCreateStatus indique la réussite ou l’échec d’une tentative de création d’un utilisateur. Si l’opération CreateUser échoue, l’énumération MembershipCreateStatus décrit la cause de l’échec.
Notes
Si vous n’êtes pas familiarisé avec les fonctionnalités d’appartenance de ASP.NET, consultez Présentation de l’appartenance avant de continuer. Pour obtenir la liste des autres rubriques relatives à l’appartenance, consultez Gestion des utilisateurs à l’aide de l’appartenance.
Si vous utilisez une CreateUser surcharge de méthode qui ne spécifie pas de paramètre de sortie de type MembershipCreateStatus, une tentative infructueuse de création d’un utilisateur lève un MembershipCreateUserException avec la StatusCode propriété définie sur l’une des valeurs d’énumération MembershipCreateStatus .
