Question

我试图让vb.net显示以hh：mm：ss格式运行的运行时间。我想让它在几秒钟内显示我能获得帮助吗？因此，例如，如果它是10:00:00 am，那么那将是10 * 60 * 60.但是时间会自动继续，如果时间是10:19:23 am那么我该怎么办？

我的代码：

Private Sub Timer1_Tick(sender As Object, e As EventArgs) Handles Timer1.Tick
    Label2.Text = Format(Now, "HH:mm:ss")
End Sub

Private Function GetSeconds(ByVal timestamp As DateTime) As Integer

    Dim timespan As TimeSpan = Now - timestamp
    Return (timespan.TotalSeconds)

End Function

Answer 1

以下几种方式可以在几秒钟内获得时间：

Dim a As Double = Now.TimeOfDay.TotalSeconds          ' 39715.561210299995
Dim b As Long   = TimeOfDay.Ticks \ 10000000          ' 39715
Dim c As Double = TimeOfDay.ToOADate * 24 * 60 * 60   ' 39715.000000000007
Dim d As Double = (Now.ToOADate Mod 1) * 24 * 60 * 60 ' 39715.000000000007

我怎么能得到hh：mm：ss在vb.net中只需几秒钟即可显示
