Description Maxim 2012-04-28 07:01:37 UTC
I'm tring to change default date format in whole app.

I'm using code:
            CultureInfo culture = (CultureInfo)CultureInfo.CurrentCulture.Clone();
            culture.DateTimeFormat.ShortDatePattern = "d MMMM yyyy";
            Thread.CurrentThread.CurrentCulture = culture;

I'm expecting to get
"28 апреля 2012", but it prints
"28 Апрель 2012".

So it utilize generic month name, not culture specified value (declination of the words).

Same with LongDatePattern. Same under latest stable Mono for Android.

I already know that we could replace culture.DateTimeFormat.MonthNames array with prepared values.

See example at http://msdn.microsoft.com/en-us/library/system.globalization.datetimeformatinfo.longdatepattern.aspx

Mono returns
"ru-RU   d MMMM yyyy 'г.'     12 Ноябрь 2001 г."
instead of
"ru-RU   d MMMM yyyy 'г.'     12 ноября 2011 г

Fixed in master
Comment 3 Maxim 2012-07-18 10:19:11 UTC
I'm sorry, It's not fixed.

When using latest stable Mono+MonoTouch run this code:
  CultureInfo culture = (CultureInfo)CultureInfo.CurrentCulture.Clone();
  culture.DateTimeFormat.ShortDatePattern = "d MMMM yyyy";
  Thread.CurrentThread.CurrentCulture = culture;

I'm expecting to get "18 июля 2012" under Russian locale,
but it prints "18 Июль 2012".
Comment 4 Marek Safar 2012-07-18 10:22:25 UTC
it has been fixed in mono master not monotouch, you need to wait for monotouch to start using mono 2.11
Comment 5 Rolf Bjarne Kvinge [MSFT] 2012-07-18 11:20:25 UTC
MonoTouch will likely switch to use Mono 2.11/2.12 some time later this year.
Comment 6 Maxim 2012-07-18 12:37:22 UTC
Oh, thanks you for info!
