SSRS中的日期表达

Question

I have written this, but it's not working:

=DateDiff("d",Fields!VDate.Value,CDate("31/03/2017")) 

When I try this, it works:

=DateDiff("d",Fields!VDate.Value,Today()) 

What's wrong in my first DateDiff ?

Answer 1

Fields!VDate.Value格式化为mm / dd / yyyy和CDate("31/03/2017")格式化为dd / mm / yyyy;），将CDate("31/03/2017")更改为CDate("03/31/2017") ，玩得开心。
