Get Change Set

Add the reference to http://tfsserver/VersionControl/v1.0/Repository.asmx

In the example this reference's name is ws

ws.Repository rep = new ws.Repository();

rep.UseDefaultCredentials = false;

rep.Credentials = new NetworkCredential(user, pass, domain);

ws.ItemSpec itemspec = new ws.ItemSpec();

itemspec.item = tfspath; // ex $/

itemspec.recurse = ws.RecursionType.Full;

ws.ChangesetVersionSpec changesetspec = new ws.ChangesetVersionSpec();

changesetspec.cs = 0;

ws.LatestVersionSpec lastspec = new ws.LatestVersionSpec();

ws.DateVersionSpec datespec = new ws.DateVersionSpec();

datespec.date = datefrom;

Changeset[] changesets = rep.QueryHistory("", "", itemspec, changesetspec, "", datespec, lastspec, 2000, true, true, true);
