VB.NET中的DateTime问题 [英] DateTime question in VB.NET

问题描述

好的，所以我需要通过编程方式找到星期一的日期。

Ok, so I need to find the date of Monday this week programmatically.

例如，本周星期一是在9日，所以我需要的日期是：09/11/2009

For example, for this week Monday was on the 9th, so the date I need is: 09/11/2009

当我们滚动到下周，它需要计算：16/11/2009

And when we roll over to next week it needs to calculate: 16/11/2009

我已经尝试这样做了，但是看不到如何做算术，谢谢。

I have tried doing this myself but I can't see how to do the arithmetic, thank you.

推荐答案

C＃：

date.AddDays(1 - (date.DayOfWeek == DayOfWeek.Sunday ? 7 : (int)date.DayOfWeek));

VB.NET：

date.AddDays(1 - IIf((date.DayOfWeek = DayOfWeek.Sunday), 7, date.DayOfWeek))
