How to get the Last Month from System.Date ??

How to get the Last Month from System.Date ??

• An_Cala

  DateTime is a class, not a method. As such, it HAS methods.

  DateTime dt2 = new DateTime(dt.Year, (dt.Month == 1) 12 : dt.Month-1, 1);

  will give you a date time of the first day in the month before the month in dt, for example.

  DateTime dtStart = new DateTime(dt.Year, Math.Ceil(dt.Month/3.0), 1);

  is a first guess at how to get the first day of a quarter.

  You can create a new date using the current month - 1. The month property is a number, so you can easily use that to generate quarters.

  Hello Christian,

  the only method I can find other that DateTime is

  MonthCalendar curr1 = new MonthCalendar();

  from here how can I subtract 1 and get the last month or this quarter...

  Thanks,

  Sorry for asking the same thing again and again..

  DateTime lastday = DateTime.LastDayInMonth;

  Error 1 'System.DateTime' does not contain a definition for 'LastDayInMonth'

  Sorry, it's

  DateTime.DaysInMonth

  and it takes a year and a month and returns a digit.

  DateTime.LastDayInMonth

  It's a static method so you won't see it on a class instance.

  Hello,

  DateTime curr = DateTime.Now;

  curr = curr.AddMonths(-1);

  double curr1 = curr.Day;

  curr1 = curr1 - 1;

  curr = curr.AddDays(-curr1);

  But then I got stuck here, curr gives me 1/1/2006 but then how can I say without comparing or by doing if else ...its Jan and add 30 days to it to get 1/31/2006.

  Or if its Feb - 2/1/2006 -- 2/28/2006

  or some other Month.....
