Answer 1

修正了它

        Dim LessThanTen As Double

    Dim Startt = DateTime.ParseExact(txttimebegin.Text, "h:mm:tt", Nothing)
    Dim Endt = DateTime.ParseExact(txttimeend.Text, "h:mm:tt", Nothing)

    Dim Duration As TimeSpan = Startt - Endt

    If Duration.TotalMinutes < 10 Then
        LessThanTen = True
    Else
        LessThanTen = False
    End If
