参考技术A textBox1.Text = monthCalendar1.SelectionStart.ToString("yyyyMMdd");
这个是显示选中日期的开始时间，如果是点击的话，就是这个语句就好。
如果是拖动选择日期段的话，这个是开始日期，
结束日期是
textBox1.Text = monthCalendar1.SelectionEnd.ToString("yyyyMMdd"); 参考技术B date=this.monthcalendar1.SelectionStart.toString(); 参考技术C SelectionStart SelectionEnd试下这两个属性

如何使用 MonthCalendar 获取“星期几”？

【中文标题】如何使用 MonthCalendar 获取“星期几”？

【英文标题】：How do I get the "Day of the Week" using MonthCalendar?

【发布时间】：2017-02-16 17:35:33

【问题描述】：

我正在使用 WinForms，我正在尝试获取星期几。

因此，如果有人选择 2/16/2017，那么我将得到星期四。

我知道 DateTimePicker 控件可以做到这一点，但我确实需要使用 monthCalendar

【问题讨论】：

DayOfWeek 是 DateTime 的一个属性

我可以将 monthCalendar 日期转换为 DAteTimePicker 对象吗？

只是 monthCalendar1.SelectionRange.Start.DayOfWeek ?

为什么投反对票？

【参考方案1】：

确实，使用DateTime.DayOfWeek的最简单方法。

mounthCalerndar.SelectionStart.DayOfWeek 

应该做的工作。
