datetime.tostring month and day language

Question

i have a list of email addresses of people that have different nationalities (for each person i have the iso code)

when i send the email to all these people, in the text of the mail i need to to convert a datetime field to a string formatted in their specific culture.

for this i'm doing

CultureInfo ci = new CultureInfo(ISO);
myStringDate = myDate.ToString(ci.DateTimeFormat.ShortDatePattern);

and work perfect, but if i use LongDatePattern instead short, for displaying date like "Monday, 13 June 2010" its work fine except the language of the day and month.

if the person culture is it-IT i need to display "Martedi" and "Giugno" not "monday" and "June"

how can i do that without change the current UI culture?

Answer 1

Those patterns describe year, month, day and other parameter locations in the output result of DateTime. But month and day names are taken from the CultureInfo object, not pattern. There's the DateTime.ToString() overload that supports passing the CultureInfo parameter along with the format.

CultureInfo culture = new CultureInfo(ISO); 
DateTime.Now.ToString(culture.DateTimeFormat.LongDatePattern, culture);

This way, .ToString() will respect both pattern and names from specified culture
