在ASP.NET Razor中寻找更好的迭代方法

<div class="container">
        @foreach (var track in tracks)
        {
            <SpeakerTrack track-name="@track">
                @foreach (var speaker in Model.Where(a => a.TrackName == track).
                     OrderBy(a => a.UserLastName))
                {
                    <Speaker speaker="@speaker"></Speaker>
                }
            </SpeakerTrack>
        }
</div>
