Editar y guardar elementos de trabajo usando el modelo de objetos de cliente para Team Foundation
Puede cambiar Fields, Links, y Attachments de WorkItem y después intentarlos para guardar esos cambios mediante WorkItem.Save o método de WorkItemStore.BatchSave .
Cuando intente guardar los cambios, se evalúan en las reglas para WorkItemType.Si los valores especificados siguen estas reglas, se guarda WorkItem , se aumenta la revisión, y el historial se actualiza con los cambios más recientes.Si no, WorkItem no se guarda, su revisión no se incrementa, y el historial no se actualiza.
[!NOTA]
Puede guardar más de un WorkItem o WorkItemLink en una única acción de ida y vuelta mediante el método de WorkItemStore.BatchSave .
Ejemplo
El ejemplo muestra cómo editar y guardar elementos de trabajo y cómo utilizar las propiedades de WorkItem.IsValid y de WorkItem.IsDirty .
Para utilizar este ejemplo
Cree una aplicación de consola de C# (o VB).
Agregue referencias a los siguientes ensamblados:
Reemplace el contenido de Program.cs (o Module1.vb) con el ejemplo siguiente:
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)
{
Console.WriteLine("The work item threw a validation exception.");
Console.WriteLine(exception.Message);
}
// Set the state to a valid value that is not the old value.
workItem.Fields["Assigned to"].Value = "ValidUser";
// If the work item is valid, save the changes.
if (workItem.IsValid())
{
workItem.Save();
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.Fields["Assigned to"].Value = oldAssignedTo;
workItem.Save();
}
}
}
