Modificare e salvare elementi di lavoro tramite il modello a oggetti del client per Team Foundation
È possibile modificare Fields, Linkse AttachmentsWorkItem e si tenta di salvare le modifiche tramite WorkItem.Save o il metodo WorkItemStore.BatchSave.
Quando si tenta di salvare le modifiche, vengono confrontati con le regole per WorkItemType. Se i valori specificati seguono le regole, WorkItem viene salvato, la revisione viene incrementato e la relativa cronologia viene aggiornata automaticamente con le modifiche più recenti. In caso contrario, WorkItem non viene salvato, la revisione non viene incrementato e la relativa cronologia non è aggiornata.
Nota
È possibile salvare più di un WorkItem o WorkItemLink in un unico round trip tramite il metodo WorkItemStore.BatchSave.
Esempio
Nell'esempio viene illustrato come modificare e salvare gli elementi di lavoro e come utilizzare le proprietà WorkItem.IsDirty e WorkItem.IsValid.
Per utilizzare questo esempio
Creare un'applicazione console VB o (C#).
Aggiungere riferimenti agli assembly riportati di seguito:
Sostituire il contenuto Program.cs o Module1.vb) con l'esempio seguente:
using System;
using Microsoft.TeamFoundation.Client;
using Microsoft.TeamFoundation.WorkItemTracking.Client;
namespace WorkItemTrackingSample
{
class Program
{
static void Main(string[] args)
{
Uri collectionUri = (args.Length < 1) ?
new Uri("http://server:port/vdir/DefaultCollection") : new Uri(args[0]);
// Connect to the server and the store.
TfsTeamProjectCollection teamProjectCollection =
new TfsTeamProjectCollection(collectionUri);
WorkItemStore workItemStore = teamProjectCollection.GetService<WorkItemStore>();
// Get a specific work item from the store. (In this case,
// get the work item with ID=1.)
WorkItem workItem = workItemStore.GetWorkItem(1);
// Set the value of a field to one that is not valid, and save the old
// value so that you can restore it later.
string oldAssignedTo = (string)workItem.Fields["Assigned to"].Value;
workItem.Fields["Assigned to"].Value = "Not a valid user";
// Display the results of this change.
if (workItem.IsDirty)
Console.WriteLine("The work item has changed but has not been saved.");
if (workItem.IsValid() == false)
Console.WriteLine("The work item is not valid.");
if (workItem.Fields["Assigned to"].IsValid == false)
Console.WriteLine("The value of the Assigned to field is not valid.");
// Try to save the work item while it is not valid, and catch the exception.
try

workItem.Save();
}
catch (ValidationException exception)

// If the work item is valid, save the changes.

Console.WriteLine("The work item was saved this time.");
}
// Restore the original value of the work item's Assigned to field, and save that change.

workItem.Save();
