Q1: vb.net 如何获取时间？

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())

Sub gettime()

   

   nowtime = Format(DateTime.Now, "yyyy/MM/dd hh:mm:ss")

Q3: 请问怎么用vb.net调出年月日

用日期函数day()可获得当前日期,time()可获得当前系统时间.

dim CurDay as string

dim CurTime as string

curday=day()

curtime=time()

Label1.Caption = Date

就能在Label16显示当前日期

now 这个函数可以获得当前系统时间（包括年月日，小时分钟秒）

而

year()

month()

day()

等等则可以从now返回的值中分别提取年，月，日的信息
