报表生成器：查找当前一周中星期一的表达式

Question

I can't figure out how to return the Monday of the current week using an expression in Report Builder 3.0 . In SQL, it's easy:

DATEADD(wk, DATEDIFF(wk,0,GETDATE()), 0)

I tried converting this to an expression like this:

=DateAdd("w", datediff("w", 0, now()), 0)

...but this returned the error: Argument 'Date1' cannot be converted to type 'Date'

您可以使用DatePart获取星期几，然后从当前日期中减去该天数（您需要添加1，因为工作日是从1开始，而不是从0开始），您可以这样做：

=DateAdd("d",1 - DatePart("w",Today,FirstDayOfWeek.Monday,FirstWeekOfYear.System),Today)
