VB.net 獲取日期

dim myMonth as string= DateTime.Now.tostring("MM")

年月日時(shí)分秒

DateTime.Now.tostring("yyyy-MM-dd hh-dd-ss") ‘得到2011-03-30 09-08-05

DateTime.Now.tostring("yy-M-d h-d-s") ‘得到11-3-30 9-8-5

vb.net中如何獲取當(dāng)前日期所在星期的星期一的具體年月日

Dim ThisDay As String = Format(Now, "yyyy-MM-dd") '獲得當(dāng)前日期字符串

Dim ThisDateTime As DateTime = Convert.ToDateTime(ThisDay) '當(dāng)前日期轉(zhuǎn)換成DateTime

Dim ThisWeekDay As Integer = ThisDateTime.DayOfWeek '獲得當(dāng)前日期是星期幾

Dim differadd As Integer = 1 - ThisWeekDay '相差的天數(shù)（星期1與當(dāng)前星期幾相差的天數(shù)）

Dim MyAdd As New TimeSpan(differadd, 0, 0, 0)

Dim MyYear As Integer = Format(Now, "yyyy") '獲取當(dāng)前日期的年份

Dim MyMonth As Integer = Format(Now, "MM") '獲取當(dāng)前日期的月份

Dim MyDay As Integer = Format(Now, "dd") '獲取當(dāng)前日期是幾號(hào)

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)

請(qǐng)問(wèn)怎么用vb.net調(diào)出年月日

用日期函數(shù)day()可獲得當(dāng)前日期,time()可獲得當(dāng)前系統(tǒng)時(shí)間.

dim CurDay as string

dim CurTime as string

curday=day()

curtime=time()

Label1.Caption = Date

就能在Label16顯示當(dāng)前日期

now 這個(gè)函數(shù)可以獲得當(dāng)前系統(tǒng)時(shí)間（包括年月日，小時(shí)分鐘秒）

而

year()

month()

day()

等等則可以從now返回的值中分別提取年，月，日的信息
