Question

Answer 1

如果你想要一个日期范围内的工作天数，你可以使用这个:

        var from = DateTime.Today.AddDays(-10);
        var to = DateTime.Today;
        var daysOfWeek = new DayOfWeek[] { DayOfWeek.Monday, DayOfWeek.Tuesday
                                          , DayOfWeek.Wednesday, DayOfWeek.Friday
                                          , DayOfWeek.Thursday };


        var days = Enumerable.Range(0, 1 + to.Subtract(from).Days)
                             .Select((n, i) => from.AddDays(i).DayOfWeek)
                             .Where(n => daysOfWeek.Contains(n.DayOfWeek));

如果您想要日期范围内的周数，请使用:

        (int)((to - from).TotalDays/7)
