Get the latest and the difference between workspaces in TFS

Question

I want to get the latest changes along with the difference between the local workspace and the server version from TFS, since I used this code, which I got from here

     private static void GetLatest(string username, string password, string path_to_download,
              string tf_src_path)
    {

        Uri collectionUri = new Uri(PathConstants.uri);

        NetworkCredential credential = new NetworkCredential(username, password);
        TfsTeamProjectCollection tfs = new TfsTeamProjectCollection(new Uri(PathConstants.uri), credential);
        tfs.EnsureAuthenticated();
        VersionControlServer vc = tfs.GetService<VersionControlServer>();
        foreach (var item in vc.GetItems(PathConstants.tfsRoot + tf_src_path, VersionSpec.Latest, RecursionType.Full).Items)
        {
            string relativePath = _BuildRelativePath(path_to_download, item.ServerItem);

            switch (item.ItemType)
            {
                case ItemType.Any:
                    throw new ArgumentOutOfRangeException("ItemType returned was Any; expected File or Folder.");
                case ItemType.File:
                    item.DownloadFile(relativePath);
                    break;
                case ItemType.Folder:
                    Directory.CreateDirectory(relativePath);
                    break;
            }
        }
    }

But this code loads all the files from the source code and replaces the existing files in the local workspace.

Is there a way to download only the difference between the local and server versions? for example, if I delete any files / folders on my local computer, they will also be downloaded along with the new files associated with the change sets, without replacing other files.

.

private static void GetLatest(string username, string password, string path_to_download,
              string tf_src_path)
    {

        Uri collectionUri = new Uri(PathConstants.uri);
        NetworkCredential credential = new NetworkCredential(username, password);
        TfsTeamProjectCollection tfs = new TfsTeamProjectCollection(new Uri(PathConstants.uri), credential);
        tfs.EnsureAuthenticated();
        VersionControlServer vc = tfs.GetService<VersionControlServer>();

        foreach (Workspace workspace in vc.QueryWorkspaces(null, null, System.Environment.MachineName))
            {
                foreach (WorkingFolder folder in workspace.Folders)
                {
                ItemSpec itemSpec = new ItemSpec(folder.ServerItem,  RecursionType.Full);
                ItemSpec[] specs = new ItemSpec[] { itemSpec };
                ExtendedItem[][] extendedItems = workspace.GetExtendedItems(specs, DeletedState.NonDeleted, ItemType.File);
                ExtendedItem[] extendedItem = extendedItems[0];
                    foreach (var item in extendedItem)
                    {
                        if (item.VersionLocal != item.VersionLatest)
                        {
                            vc.DownloadFile(item.SourceServerItem, item.LocalItem);
                        }
                    }
                }
            }
        }
