Q1: 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

Q2: vb.net中如何获取当前日期所在星期的星期一的具体年月日

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)

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

Q4: VB如何获取系统当前的系统时间？

vb中获取系统当前的时间用函数 now() 就可以。另外还有相关的时间 date() time()\x0d\x0anow()获取系统当前日期和时间，如：2015-12-12 22：23：34\x0d\x0atime()获取系统的时间，如：22：23：34不显示当前日期\x0d\x0adate()获得系统的日期，如：2015-12-12\x0d\x0a\x0d\x0aPrivate Sub Command1_Click()\x0d\x0aMsgBox Now()\x0d\x0aMsgBox Time()\x0d\x0aMsgBox Date\x0d\x0aEnd Sub

Q5: 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())

End Sub
