年月日时分秒
DateTime.Now.tostring("yyyy-MM-dd hh-dd-ss") ‘得到2011-03-30 09-08-05
DateTime.Now.tostring("yy-M-d h-d-s") ‘得到11-3-30 9-8-5
怎么在VB.NET中,提取系统日期中的后的 月和日 的位数
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim a As Short = Date.Now.Month
Dim b As Short = Date.Now.Day
MessageBox.Show(a)
MessageBox.Show(b)
End Sub
上面是获取月份以及天数
'======================
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim a As Short = Date.Now.Month
Dim b As Short = Date.Now.Day
Dim c, d As String
If a 0 AndAlso a 10 Then
c = "1位数"
Else
c = "2位数"
End If
If b 0 AndAlso b 10 Then
d = "1位数"
Else
d = "2位数"
End If
MessageBox.Show(c)
MessageBox.Show(d)
End Sub
这个是获取位数的
vb点虐 中怎么获取日期中的年月日时分秒
Dim ThisDay As String = Format(Now, "yyyy-MM-dd") '获得当前日期字符串
Dim ThisDateTime As DateTime = Convert.ToDateTime(ThisDay) '当前日期转换成DateTime
Dim ThisWeekDay As Integer = ThisDateTime.DayOfWeek '获得当前日期是星期几
Dim differadd As Integer = 1 - ThisWeekDay '相差的天数(星期1与当前星期几相差的天数)
Dim MyAdd As New TimeSpan(differadd, 0, 0, 0)
Dim MyYear As Integer = Format(Now, "yyyy") '获取当前日期的年份
Dim MyMonth As Integer = Format(Now, "MM") '获取当前日期的月份
Dim MyDay As Integer = Format(Now, "dd") '获取当前日期是几号
Dim MyToday As DateTime = New DateTime(MyYear, MyMonth, MyDay)
Dim Yourday As DateTime = MyToday.Add(MyAdd)
MsgBox("本周星期一的日期是:" Yourday)
vb点虐 获取年,月,日,时,分,秒
不是 有 函数嘛?
now() 就是 吧
取得 后 再 分离出你所需的,分别赋值 就行了,当然 还是 有 函数的
