Exemples
L'exemple suivant est une application console qui interroge toutes les listes de tâches dans une collection de sites. La chaîne de requête sélectionne les tâches qui sont affectées à l'utilisateur en cours, classée par date d'échéance. Notez que le code obtient les ID pour les champs utilisés dans la requête en accédant à des données membres de la classe SPBuiltInFieldId .
