Get labels applied to a particular version of an item in TFS source control

labelstfs

I'm trying to get a list of labels that apply to a particular version of a particular file in TFS Source Control. So far, I've gotten a set of labels that apply to any version of a particular file. Does anyone have any experience getting labels for a particular item?

For example, I have $/Project/Folder/Item.cs, which was modified in changesets 301, 401, and 601. Labels Build1 – Build 99 exist for the project. Build1 – Build10 were applied before changeset 301 (i.e. before Item.cs was created). Build96 – Build99 were applied to the v601 of Item.cs. If I run 

vcServer.QueryLabels(null, "$/Project", null, false, "$/Project/Folder/Item.cs", new ChangesetVersionSpec(6))

I get Build11 – Build99 as results. I haven't figured out how to get a query to return fewer than this many labels. Ideally, the query I run will return 4 labels (Build96 – Build 99).

The context of this question is a TFS Project, with CCNET for a build server. I'm trying to relate work items to builds, starting with a work item number.

Any tips? Or examples of QueryLabels? Or better docs for QueryLabels than the MSDN docs?

This is possible, see here: http://social.msdn.microsoft.com/Forums/en-US/tfsversioncontrol/thread/9f41f37e-4fda-4b56-91a3-f2b7e0c0e22d

Basically, once you get back the list of labels, you have to look through each label and see what changeset of the item you're interested in it applies to. Be sure to pass in the "includeItems = false" flag to QueryLabels, otherwise you'll have to look through every item on the label.
