ProjectContext.WaitForQueue - Méthode
Attend que la tâche de file d'attente spécifiée à terminer, ou pour un nombre maximal de secondes.
Espace de noms : Microsoft.ProjectServer.Client
Assembly : Microsoft.ProjectServer.Client (dans Microsoft.ProjectServer.Client.dll)
Syntaxe
'Déclaration
Public Function WaitForQueue ( _
job As QueueJob, _
timeoutSeconds As Integer _
) As JobState
'Utilisation
Dim instance As ProjectContext
Dim job As QueueJob
Dim timeoutSeconds As Integer
Dim returnValue As JobState
returnValue = instance.WaitForQueue(job, _
timeoutSeconds)
public JobState WaitForQueue(
QueueJob job,
int timeoutSeconds
)
Paramètres
job
Type : Microsoft.ProjectServer.Client.QueueJobUn objet qui représente la tâche en file d'attente.
timeoutSeconds
Type : System.Int32Le nombre maximal de secondes à attendre pour la fin du travail de file d'attente.
Valeur renvoyée
Type : Microsoft.ProjectServer.Client.JobState
L'état de la tâche de file d'attente. Si la tâche se termine correctement, renvoie la valeur JobState.Success.
Exemples
L'exemple de Console nommé QueueCreateProject effectue les tâches suivantes :
Analyse la ligne de commande pour obtenir le nom d'un nouveau projet et un délai d'attente de travail facultatif de file d'attente. Le délai d'attente par défaut est de 10 secondes. Par exemple, si un projet nommé projet Test 1 n'existe pas dans Project Web App, vous pouvez exécuter l'application avec la commande QueueCreateProject -projName "Test proj 1" .
Crée un objet ProjectContext pour l'instance spécifiée de Project Web App .
Obtient le GUID du type de projet entreprise (EPTER) nommé « Plan de projet de base ».
Crée un projet à l'aide de la méthode CreateTestProject , qui définit les propriétés d'un objet ProjectCreationInformation .
Attend que le Service de file d'attente de Project Server publier le nouveau projet, à l'aide de la méthode ProjectContext.WaitForQueue .
Répertorie les projets publiés. Si l'application QueueCreateProject n'appelle pas la méthode WaitForQueue , les projets publiés incluent ne peut-être pas encore le nouveau projet.
