using Microsoft.TeamFoundation.VersionControl.Client;

public void GetChangesetsInfo()

        {

            TfsTeamProjectCollection proj_coll = new TfsTeamProjectCollection(new Uri("http://NvnTfsserver:8080/tfs/defaultcollection/"), new System.Net.NetworkCredential(username, password));

            proj_coll.EnsureAuthenticated();

            VersionControlServer vcs = (VersionControlServer)proj_coll.GetService(typeof(VersionControlServer));

            //Following will get all changesets since 20 days. Note : "DateVersionSpec(DateTime.Now - TimeSpan.FromDays(20))"

            System.Collections.IEnumerable history = vcs.QueryHistory("$/Stakeholders Test Project", LatestVersionSpec.Instance, 0, RecursionType.Full, null, new DateVersionSpec(DateTime.Now - TimeSpan.FromDays(20)), LatestVersionSpec.Instance, Int32.MaxValue, false, false);

            foreach (Changeset changeset in history)

            {

                Console.WriteLine("Changeset Id: " + changeset.ChangesetId);

                Console.WriteLine("Owner: " + changeset.Owner);

                Console.WriteLine("Date: " + changeset.CreationDate.ToString());

                Console.WriteLine("Comment: " + changeset.Comment);

                Console.WriteLine("-------------------------------------");
