May i know
how to get last date of current year in vb.net.

eg. last date of this year =31/12/2012

推荐答案

new DateTime(DateTime.Now.Year, 12, 31)

试试看:
获取年份的功能:

Try this:
Function for getting year:

Private Function LastDayOfYear(ByVal d As DateTime) As DateTime
   Dim time As New DateTime((d.Year + 1), 1, 1)
   Return time.AddDays(-1)
   End Function

调用函数:

Calling Function:

Dim d As New DateTime(2012, 7, 1)
    Console.WriteLine("Last day of 2012: {0}", LastDayOfYear(d))

参考号: DateTime VB.NET [ DateTime.Year属性 [ DateTime.DayOfYear属性 [

Ref.:DateTime VB.NET[^]

Also have a look on:
DateTime.Year Property[^]
DateTime.DayOfYear Property[^]

可以获取天数一个月.

to get the no of days in a month.

<br />
int days = DateTime.DaysInMonth(DateTime.Now.Year, DateTime.Now.Month);<br />

最终将显示您当前月最后一个日期的要求.

ultimately the requirement of your last date of current month will shown.
