TimeSpan between two DateTimes
提问by Lexy Feito
I'm trying to find out the time span between two dates.
我试图找出两个日期之间的时间跨度。
What I have this so far:
到目前为止我有什么：
dim start as DateTime = now
dim stop as DateTime = now
dim span as TimeSpan = stop.Subtract(start)
But I don't the the correct answer.
但我不知道正确答案。

This gives the time elapsed since Jan 1, 2013:
这给出了自 2013 年 1 月 1 日以来经过的时间：
Dim start as DateTime = #1/1/2013#
Dim stop as DateTime = Now
Dim elapsed As TimeSpan = start.Subtract(stop)
Console.Write(elapsed.Days & " days, " & elapsed.Hours & " hours, " & elapsed.Minutes & " minutes, " & elapsed.Seconds & " seconds.")

You cannot use "stop", "end"as Variable .. This should be works (tested on VS2005)
你不能使用"stop", "end"作为变量 .. 这应该是有效的（在 VS2005 上测试）
dim start as DateTime = now
dim stops as DateTime = now
dim span as TimeSpan = stops.Subtract(start)

Looks fine to me.
对我来说看起来不错。
E.g.
例如
Dim startTime As DateTime = New DateTime(2013, 6, 12, 22, 45, 0)
Dim endTime As DateTime = New DateTime(2013, 6, 12, 22, 50, 0)
Dim span As TimeSpan = endTime - startTime
Result: 00:05:00
结果：00:05:00
