Question

我试图找出两个日期之间的时间跨度。

到目前为止我有这个：

 dim start as DateTime = now
 dim stop as DateTime = now
 dim span as TimeSpan = stop.Subtract(start)

但我没有正确答案。

Answer 1

这给出了自2013年1月1日起的时间：

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.")

Answer 2

对我来说很好。

E.g。

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

结果：00：05：00

Answer 3

您无法使用“停止”，“结束”作为变量..这应该可行（在VS2005上测试）

dim start as DateTime = now
dim stops as DateTime = now
dim span as TimeSpan = stops.Subtract(start)

TimeSpan在两个DateTime之间
