如何判断时间小于7:30:00呀
[解决办法]
直接比较就行了
Dim d1 As New Date(2001, 1, 1)
Dim d2 As New Date(2001, 1, 1, 7, 30, 0)
MsgBox(d1 < d2)
[解决办法]
Dim D1, D2 As Date
Dim D As Date = "2007-01-01 07:00:00" '比较的标准时
D1 = "2007-01-01 05:20:20"
D2 = "2007-01-01 07:20:20"
Dim i As Int32
i = DateDiff(DateInterval.Second, D1, D)
MsgBox(i)
End Sub
还要注意日期
[解决办法]
If TimeOfDay <= CDate("07:30:00") Then
[解决办法]
Function Foo(ByVal dt As DateTime) As Boolean
Dim span As New TimeSpan(7, 30, 0)
Return dt.TimeOfDay < span
End Function
