我在 VB.NET 2008 中每周使用 datetime 尝试循环。
本守则
Private Sub Button1_Click()....
'Select DateTime
Dim strDate As Date = dateTimePicker.Value.ToString("yyyy-MM-dd")
'one week (+7)
Dim strDateWeek As String = DateAdd("d", +7, dateTimePicker.Value.ToString("yyyy-MM-dd"))
'DateCurrent
Dim strDateNow As String = DateAdd("d", 0, Now.ToLongDateString())
'While strDate < strDateNow
'ListBox1.Items.Add(strDateWeek)
'End While
ListBox1.Items.Add(strDateWeek)
End Sub
例子
I select on datetimepicker at "04/02/2013"
Output now: 11/02/2013
But I need Output each on weekly
11/02/2013
18/02/2013
25/02/2013 >>> To Current Week
我尝试循环while,但不工作。
谢谢你的时间。:)
