vb.net 如何获取时间？

请问在vb.net 如何获取日期中的年、月、日、分、秒，并转化字符串或整数。如2011年7月6日15时20分25秒。获取到后转化为：20110706152025 这样的一串数字的程序怎么写，谢谢。

Answer 1

两种方式自己选用
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

Answer 2

可以先用datetime.Now.ToString 获得到当前时间，然后把这个字符串中的“/”和“:” trim掉就可以了

Answer 3

MsgBox(Now.ToString("yyyyMMddHHmmss"))
