Getting Changeset objects from associated work items
On internal mailing list, someone asked how to do this, and I thought it's worth sharing. You can get a Changeset object using its artifact URI (aka link) via VersionControlServer.ArtifactProvider. Here’s how that would look like, based on modifying code from James Manning’s blog posthttp://blogs.msdn.com/jmanning/archive/2005/09/21/472524.aspx. Added/changed lines are hightlighted.
using System;
using System.Collections.Generic;
using Microsoft.TeamFoundation.Client;
using Microsoft.TeamFoundation.WorkItemTracking.Client;
using Microsoft.TeamFoundation;
using Microsoft.TeamFoundation.VersionControl.Client;
class ChangesetsFromWorkItems
{
static void Main(string[] args)
{
if (args.Length < 2)
{
Console.Error.Write("Usage: ChangesetsFromWorkItems <server> <workitemid> [workitemid...]");
Environment.Exit(1);
}
TeamFoundationServer server = TeamFoundationServerFactory.GetServer(args[0]);
WorkItemStore wiStore = (WorkItemStore)server.GetService(typeof(WorkItemStore));
VersionControlServer vcs = (VersionControlServer) server.GetService(typeof(VersionControlServer));
int workItemId;
for (int i = 1; i < args.Length; i++)
{
if (!int.TryParse(args[i], out workItemId))
{
Console.Error.WriteLine("ignoring unparseable argument {0}", args[i]);
continue;
}
WorkItem workItem = wiStore.GetWorkItem(workItemId);
List<Changeset> associatedChangesets = new List<Changeset>();
foreach (Link link in workItem.Links)
{
ExternalLink extLink = link as ExternalLink;
if (extLink != null)
{
ArtifactId artifact = LinkingUtilities.DecodeUri(extLink.LinkedArtifactUri);
if (String.Equals(artifact.ArtifactType, "Changeset", StringComparison.Ordinal))
{
// Convert the artifact URI to Changeset object.
associatedChangesets.Add(vcs.ArtifactProvider.GetChangeset(new Uri(extLink.LinkedArtifactUri);
}
}
}
// Do something with the changesets. Changes property is an array, each Change
// has an Item object, each Item object has a path, download method, etc.
}
}
}
