Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

Dim s As String

s = DateTime.Today.Year()

s = s DateTime.Today.Month()

s = s DateTime.Today.Day()

s = s DateTime.Now.Hour()

s = s DateTime.Now.Minute()

s = s DateTime.Now.Second()

MsgBox(s, vbDefaultButton1, Now())

End Sub

Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click

Dim s As String

s = Format(Now(), "yyyymmddhhmmss")

MsgBox(s, vbYes, Now())

End Sub

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)

用Date直接得到日期，不要用now。

有格式方面的要求，再用 format
