Écrire du code pour différents types d'éléments de travail à l'aide du Modèle d'objet client pour Team Foundation
Lorsque vous écrivez du code pour des projets d'équipe, vous pouvez remplir la même fonction sur différents types d'éléments de travail qui répondent aux objectifs semblables.Ces types peuvent être différents parce qu'ils proviennent de différents modèles de processus, ou une équipe peut les être personnalisés pour un projet d'équipe spécifique.Par exemple, vous pouvez remplir la même fonction de les récits utilisateur et des spécifications, qui doivent représenter les clients requièrent et évaluent.Au lieu de code distinct d'écriture pour chaque type d'élément de travail, vous pouvez généraliser votre code fonctionne pour les deux.En outre, une équipe peut avoir personnalisé la définition d'élément de travail pour les récits utilisateur afin que les membres de l'équipe puissent estimer le travail en heures et non à des points de récit.Vous pouvez éviter de dupliquer votre propre travail en ajustant votre code pour gérer la valeur par défaut et les stratégies personnalisées.
Dans cette rubrique, vous trouverez un exemple de code qui effectue une tâche sur un type spécifique d'élément de travail qui n'a pas été personnalisé, puis vous explique comment refactoriser le code pour prendre en charge certains genres de personnalisations.Pour plus d'informations sur la personnalisation de types d'éléments de travail, consultez Personnaliser les projets et processus d'équipe.

Imprimez les arborescences des récits utilisateur avec des estimations des points de récit
Imprimez les arborescences des récits utilisateur selon des évaluations dans les points de récit ou le travail planifié
Imprimez les arborescences d'éléments de travail utilisés comme spécifications selon des évaluations
Imprimez les arborescences des récits utilisateur avec des estimations des points de récit
Cet exemple de code imprime les arborescences de tous les récits utilisateur dans chaque projet d'équipe sur un serveur et inclut des estimations pour chaque récit qui n'a aucun enfant.Pour utiliser cet exemple, vous créez une application console, ajoutez des références aux assemblys suivants, puis remplacez le contenu (Program.cs ou Module1.vb) par le code suivant.

Imprimez les arborescences des récits utilisateur selon des évaluations dans les points de récit ou le travail planifié
Cet exemple modifie la méthode de PrintTrees pour déterminer si chaque élément de travail utilise les points de récit champ ou le champ de travail de ligne de base et imprimer l'évaluation de ce champ.Pour utiliser cet exemple, remplacez la ligne Console.WriteLine(target.Fields["Story Points"].Value); dans la méthode de PrintTrees par le code suivant.
// Determine which estimation field is present
string fieldName = "Story Points";
if (target.Type.FieldDefinitions.TryGetByName(fieldName) == null)

fieldName = "Baseline Work";

Console.WriteLine(target.Fields[fieldName].Value);
