c# - Datetime string formatting and CultureInfo -

i suprised see fxcop complaining wasn't specifying cultureinfo in following:

string s = day.tostring("ddd"); 

surely format string param in tostring independent of cultureinfo? there way cultureinfo affect returned string?

edit: sorry, total fail of question. it's obvious "ddd" should dependent on culture settings. thinking more of case datetime.now.tostring("dd-mm-yy"), looks fxcop doesn't in fact complain in instance.

there article on msdn on how extract day of week specific date. find many different examples on culture on page, including one:

datetime datevalue = new datetime(2008, 6, 11); console.writeline(datevalue.tostring("ddd"));    // displays wed  datetime datevalue = new datetime(2008, 6, 11); console.writeline(datevalue.tostring("ddd",                    new cultureinfo("fr-fr")));    // displays mer.
