TFS API: Retrieve changesets from main branch using VersionControlServer.QueryHistory

Question

Given: TFS server with m > n changesets in team project X.

I am using TFS API and would like to get the n latest changesets of that branch.

I think I should be using VersionControlServer.QueryHistory, but I don't understand how I can specify that I want all commits from main (default) branch of project X, but none from any other branch or from another team project in the collection.

Answer 1

If you only want changes in $/Project/Some/Path, then that should be the first argument to QueryHistory. For example:

QueryHistory("$/Project/Some/Path", RecursionType.Full, 5);

Will show the most recent 5 changesets that affected $/Project/Some/Path.

Answer 2

This worked for me - I had to use the QueryHistoryParameters overload and set SortAscending = false in order to get the latest changeset id and not the first changesetid.

var p = new QueryHistoryParameters(item.ServerItem, RecursionType.Full) {SortAscending = false};
var q = versionControl.QueryHistory(p);
var lastCs = q.FirstOrDefault();

if (lastCs != null)
    item.LastChangesetId = lastCs.ChangesetId;
