如何将此GROUP BY/MIN SQL查询转换为LINQ？

var query = myDataContext.ChapterMeeting
  .GroupBy(cm => cm.ChapterID)
  .Select(g => new {
      g.Key,
      MinMeetingDate = g.Min(cm => cm.MeetingDate)
  });

嗯,大卫打败了我,但如果你想用"理解"语法看到它:

var q = (
    from cm in context.ChapterMeeting
    group cm by cm.ChapterID into cmg
    select new {
        ChapterID = cmg.Key,
        FirstMeetingDate = cmg.Min(cm => cm.MeetingDate)});
