Stream file rather than downloading

foreach (var file in files)

        session.PutFile(stream, remotepath, options);

    }
    catch (Exception ex)
    {
        //I catch everything here, but I'm only concerned with the exception
        //throw for this single file upload
        await Approvals.SetStatusAsync(file.RowKey, CitStatus.TransferError);
