Need to know build no using work item number in TFS

I have TFS serv开发者_StackOverflow中文版er 2008. When we select any paricular build we use to get the work items involved in that build. I need to know in the reverse way i.e. if I know work item number then I can directly find the build number. Any help will be great.

From the Team Explorer UI, I don't believe there is a way to find a build by WI.

Using TFS API, I am sure you could build up a query to do this. I know how to get all changesets that are associated with a WI and from there I am sure you can build it up to find all builds associated with a changeset.
