Question

我需要从标签上的日历控件打印选定的一周。所选周将从周一到周日。它必须看起来像这样：2015-09-29 - 2015-10-04。在此先感谢您的帮助！

以下是我到目前为止尝试过的代码，但此代码仅打印该周的各个日期。

        DateTime input = Calendar1.SelectedDate;
        int delta = DayOfWeek.Sunday - input.DayOfWeek;
        DateTime firstDay = input.AddDays(delta);

        Label3.Text = string.Empty;

        for (int i = 0; i < 7; i++)
            Label3.Text += ((DateTime)(firstDay.Add(new TimeSpan(i, 0, 0, 0)))).ToShortDateString() + "  ";

Answer 1

// Since Sunday has the index of 0, and you want the week to start from Monday,
// we need to shift the numbers around so that Monday is 0 instead.
int dayNumber = ((int)Calendar1.SelectedDate.DayOfWeek + 6) % 7;

DateTime monday = Calendar1.SelectedDate.AddDays(-dayNumber);
DateTime sunday = Calendar1.SelectedDate.AddDays(6 - dayNumber);

Label3.Text = string.Format(
    "{0} - {1}",
    monday.ToShortDateString(),
    sunday.ToShortDateString());

从标签上的日历控件打印选定的周。
