1).Where(a => a.StartTime.CompareTo('2015-04-08') > 0) 2).Where(a => a.StartTime.CompareTo('2015-04-08') >= 0) 3).Where(a => a.StartTime.CompareTo('2015-04-08') < 0) 4).Where(a => a.StartTime.CompareTo('2015-04-08') <= 0) |
更規範的寫法:

1).Where(a => String.Compare(a.StartTime, '2015-04-08', StringComparison.Ordinal) > 0) 2).Where(a => String.Compare(a.StartTime, '2015-04-08', StringComparison.Ordinal) >= 0) 3).Where(a => String.Compare(a.StartTime, '2015-04-08', StringComparison.Ordinal) < 0) 4).Where(a => String.Compare(a.StartTime, '2015-04-08', StringComparison.Ordinal) <= 0) |
