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)
【vb.net读取时间的简单介绍】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

vb 。net怎么获取网络上的时间 坐等Dim obj,OBJStatus As Object,url As String,GetText As String,i As Integer
Dim Retrieval
url=""
'判断网络是否连接
If url""Then
Retrieval=GetObject("winmgmts:\\.\root\cimv2")
obj=Retrieval.ExecQuery("Select*FromWin32_PingStatusWhereAddress='"Mid(url,8)"'")
For Each OBJStatus In obj
If IsNothing(OBJStatus.StatusCode) Or OBJStatus.StatusCode0 Then
Exit Sub
Else
Exit For'已连接则继续
End If
Next
End If
'通过下载网页头信息获取网络时间
Retrieval=CreateObject("Microsoft.XMLHTTP")
With Retrieval
.Open ( "Get",url,False,"","")
.setRequestHeader ("If-Modified-Since","0")
.setRequestHeader ("Cache-Control","no-cache")
.setRequestHeader ("Connection","close")
.Send()
If.Readystate4 Then Exit Sub
GetText=.getAllResponseHeaders()
i=InStr(1,GetText,"date:",vbTextCompare)
If i0 Then'网页下载成功
i=InStr(i,GetText,",",vbTextCompare)
GetText= Trim(Mid(GetText,i+1))
i=InStr(1,GetText,"GMT",vbTextCompare)
GetText=GetText.Substring(0,i-1)'Left(GetText,i-1)
MsgBox ("网络时间:"GetText)
End If
End With
Retrieval=Nothing
OBJStatus=Nothing
obj=Nothing
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 = sDateTime.Today.Month()
s = sDateTime.Today.Day()
s = sDateTime.Now.Hour()
s = sDateTime.Now.Minute()
s = sDateTime.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
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
vb net获取系统时间Sub gettime()
nowtime = Format(DateTime.Now, "yyyy/MM/dd hh:mm:ss")
MsgBox nowtime
End Sub
其中DateTime.Now为当前系统的时间
Format是设置时间格式
效果如下
vb.net如何获取完整时间用大写vb.net读取时间的H可以显示24小时制vb.net读取时间：
(Format(DateTime.Now, "yyyyMMddHHmmss")).ToString
