Finding changesets associated with the work item or having specific comment TFS Api

Question

I\'m trying to find all changesets associated with the work item using Microsoft.TeamFoundation.WorkItemTracking.Client. Using query I was able to get the information about

Answer 1

Check the REST API:

GET https://{instance}/defaultcollection/_apis/tfvc/changesets/{id}?api-version={version}[&includedetails={boolean}&includeworkitems={boolean}&includesourcerenames={boolean}&maxchangecount={int}&maxcommentlength={int}]

Answer 2

After more googling on the subject and exploring tfs API here is what I ended up with:

If all you changesets are linked to the work items (not really my case but this is what I originally was asking about):

// based on https://etoptanci.wordpress.com/2011/05/04/seeing-all-code-changes-for-a-work-item/
private static void GetChangesForWorkItem()
{
    var configurationServer = TfsConfigurationServerFactory.GetConfigurationServer(new Uri(@"http://myserver:8080/tfs"));
    var tpcService = configurationServer.GetService<ITeamProjectCollectionService>();
    var collectionNodes = configurationServer.CatalogNode.QueryChildren(
           new[] { CatalogResourceTypes.ProjectCollection },
           false, CatalogQueryOptions.None);

    var collectionNode = collectionNodes.First(x => x.Resource.DisplayName == "<collection name>");

    // Use the InstanceId property to get the team project collection
    Guid collectionId = new Guid(collectionNode.Resource.Properties["InstanceId"]);
    TfsTeamProjectCollection collection = configurationServer.GetTeamProjectCollection(collectionId);
    var vcs = collection.GetService<VersionControlServer>();
    var store = new WorkItemStore(collection);
    var workItems = new List<WorkItem>()
    {
        store.GetWorkItem(1123),
        store.GetWorkItem(1145),
    };

    var associatedChangesets = new List<Changeset>();

    foreach (var workItem in workItems)
    {
        foreach (var link in workItem.Links) 
        {
            if((link==null) || !(link is ExternalLink))
            continue;

            string externalLink = ((ExternalLink)link).LinkedArtifactUri;
            var artifact =LinkingUtilities.DecodeUri(externalLink);

            if (artifact.ArtifactType == "Changeset")
                associatedChangesets.Add(vcs.ArtifactProvider.GetChangeset(new Uri(externalLink)));
        }
    }

    Console.WriteLine(associatedChangesets.Select(x=>x.ChangesetId).OrderBy(x => x));
}

If you need to get by comment as well then you gate all changesets for the daterange and then filter out by Changeset.Comment which is a string.

You can also use RestAPI (as stated in the first answer)

You need to filter out "relations" array with rel == "ArtifactLink"
