Scrittura di codice per diversi tipi di elementi di lavoro tramite il modello a oggetti del client per Team Foundation
Quando si scrive codice per i progetti team diversi, è possibile eseguire la stessa funzione con diversi tipi di elementi di lavoro che hanno scopi analoghi. Questi tipi possono essere differenti perché sono derivati dai modelli di processo diverso, o un team può personalizzarli per un progetto team specifico. Ad esempio, è possibile eseguire la stessa funzione storie utente e i requisiti, costituiti entrambi devono rappresentare che richiedono clienti e valore. Anziché scrivere codice separato per ogni tipo di elemento di lavoro, è possibile generalizzare il codice per l'utilizzo di entrambi. Inoltre, un team può personalizzare la definizione dell'elemento di lavoro per le storie utente in modo da poter stimare i membri del team il lavoro in ore nei punti della storia. È possibile evitare di duplicare il proprio operazione regolando il codice per gestire sia quello predefinito che le strategie personalizzate.
In questo argomento, è disponibile un esempio di codice che esegue un'attività in un tipo di elemento di lavoro specifico non personalizzato e quindi viene illustrato come eseguire il refactoring del codice per supportare determinati tipi di personalizzazioni. Per ulteriori informazioni su come personalizzare i tipi di elementi di lavoro, vedere Visualizzazione end-to-end di ciò che è possibile configurare e personalizzare in Visual Studio TFS.

Stampare le strutture ad albero di storie utente con le stime in punti della storia
Questo esempio di codice viene visualizzato in strutture ad albero di tutte le storie utente in ogni progetto team in un server e include le stime per ogni storia che non ha figli. Per utilizzare questo esempio, si crea un'applicazione console, aggiungere riferimenti ai seguenti assembly e quindi sostituire il contenuto Program.cs o Module1.vb) con il codice seguente.

Stampare le strutture ad albero di storie utente con le stime dei punti della storia o in Lavoro previsto
In questo esempio viene modificato il metodo di PrintTrees per determinare se ogni elemento di lavoro utilizza i punti della storia sistema o il campo di base di lavoro e per stampare la stima del campo. Per utilizzare questo esempio, sostituire la riga Console.WriteLine(target.Fields["Story Points"].Value); nel metodo di PrintTrees con il codice seguente.
// 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);
Dim fieldName As String
fieldName = "Story Points"
If (target.Type.FieldDefinitions.TryGetByName(fieldName) Is Nothing) Then
fieldName = "Baseline Work"
End If
Console.WriteLine(target.Fields(fieldName).Value)
Strutture ad albero di stampa di tutti gli elementi di lavoro in una categoria
È possibile raggruppare categorie di diversi tipi di elementi di lavoro che hanno lo stesso o simili scopi in progetti team diversi. È possibile scrivere codice per eseguire la stessa funzione su tutti gli elementi di lavoro che appartengono a una categoria. L'esempio visualizza le stime per qualsiasi tipo di elemento di lavoro nella categoria di requisiti, quali storie utente, i requisiti e elementi di backlog del prodotto.
Per utilizzare questo esempio, sostituire la funzione principale dell'esempio precedente con il codice seguente.
