find the difference between two datetimes in seconds
提问by Pezzzz
I have had a quick look around and I can't find an answer to this in vb.net or something that I can convert into vb.net.
我快速浏览了一下，但在 vb.net 或我可以转换为 vb.net 的东西中找不到答案。
I have two DateTimes in vb.net's 'Date' class. I would like to find the difference between these in seconds. I can do a-b, but the answer will still be a 'date'. I can use .seconds.minutesetc. and multiply but I will hit problems when I come to months.
我在 vb.net 的“Date”类中有两个 DateTime。我想在几秒钟内找到它们之间的区别。我可以做 ab，但答案仍然是“约会”。我可以使用.seconds.minutesetc. 和乘法，但是当我到几个月时会遇到问题。
Is there a simple way to do this, or do I need to write some elaborate-ish code?
有没有一种简单的方法可以做到这一点，或者我是否需要编写一些精心设计的代码？
Many Thanks

There actually is also a function made for this DateDiff(DateInterval.Second, d1, d2)
实际上还有一个功能是为此 DateDiff(DateInterval.Second, d1, d2)

How about something like
怎么样的东西
Dim secs As Double = DateTime.Today.Subtract(DateTime.Today.AddDays(-1)).TotalSeconds
Look at DateTime.Subtract Method (DateTime)and TimeSpan.TotalSeconds Property
查看DateTime.Subtract Method (DateTime)和TimeSpan.TotalSeconds 属性
