Question

I’ve been playing about with the WorkItem objects from the Microsoft.TeamFoundation schemas in C#, but was wondering if anyone knows how I would refer to an object of type ‘Area’ or, for that matter, ‘Iteration’.

It seems that these are treated as objects in TFS, but I haven’t come across any information on how to refer to these in C#.

You can filter WorkItems by [Area] or [Iteration] using WIQL, but what if I wanted to populate a ComboBox with all Areas or Iterations?

Also, how can I view the database structure of my workplace’s TFS project?

Thanks guys,

Andy

Have a look at this Blog Post. There’s sample code and a demo.

Here’s a quick LINQPad Query that should do the job (download VS2010 / VS2012):

void Main()
{
    const String CollectionAddress = "http://tfsserver:8080/tfs/MyCollection";
    const String ProjectName = "MyProject";

    using (var tfs = TfsTeamProjectCollectionFactory.GetTeamProjectCollection(
        new Uri(CollectionAddress)))
    {
        tfs.EnsureAuthenticated();
        var server = tfs.GetService<ICommonStructureService>();

        var projectInfo = server.GetProjectFromName(ProjectName);
        var nodes = server.ListStructures(projectInfo.Uri).Dump();

        // You should be able to re-factor this with "Iteration"
        // for getting those too.
        var nodesXml = server.GetNodesXml(
            nodes
                .Where(node => node.Name == "Area")
                .Select(node => node.Uri).ToArray(),
            true);

        var areaPathAndId =
            XElement.Parse(nodesXml.OuterXml)
            .Descendants("Node")
            .Select(xe => new 
            { 
                Path = xe.Attribute("Path").Value, 
                ID = xe.Attribute("NodeID").Value, 
            })
            .Dump();        
    }
}
