Modifier et enregistrer des éléments de travail à l'aide du Modèle d'objet client pour Team Foundation
Vous pouvez modifier Fields, Links, et Attachments d' WorkItem puis de tenter d'enregistrer ces modifications à l'aide de WorkItem.Save ou de la méthode d' WorkItemStore.BatchSave .
Lorsque vous essayez d'enregistrer vos modifications, ils sont évalués sur les règles de WorkItemType.Si les valeurs que vous spécifiez suivez ces règles, WorkItem est enregistré, sa balise est incrémentée, et son historique est mis à jour avec les modifications les plus récentes.Sinon, WorkItem n'est pas enregistré, la révision n'est pas incrémentée, et son historique n'est pas mis à jour.
[!REMARQUE]
Vous pouvez enregistrer plusieurs WorkItem ou WorkItemLink dans une boucle à l'aide de la méthode d' WorkItemStore.BatchSave .
Exemple
L'exemple montre comment modifier et enregistrer des éléments de travail et comment utiliser les propriétés d' WorkItem.IsValid et d' WorkItem.IsDirty .
Pour utiliser cet exemple
Créez une application console C# (ou VB).
