Convert String to DateTime in C# - String was not recognized as a valid DateTime -

i reviewed question here: convert string datetime in c#.net

the format i'm trying pass different, cannot work.

my code:

var date = datetime.parseexact(@"28/06/2012 06:04:10 pm", @"dd/mm/yyyy hh:mm:ss tt", null); 

so tried example code question mentioned above:

var date = datetime.parseexact(@"14/04/2010 10:14:49.pm", @"dd/mm/yyyy hh:mm:ss.tt", null); 

that doesn't work either. both give me

system.formatexception string not recognized valid datetime. 

any ideas appreciated! thanks!

the problem localisation.

consider these 3 statements:

datetime.parseexact(@"14/04/2010 10:14:49.pm", @"dd/mm/yyyy hh:mm:ss.tt", new cultureinfo("fr-fr")) datetime.parseexact(@"14/04/2010 10:14:49.pm", @"dd/mm/yyyy hh:mm:ss.tt", new cultureinfo("en")) datetime.parseexact(@"14/04/2010 10:14:49.pm", @"dd/mm/yyyy hh:mm:ss.tt", cultureinfo.invariantculture) 

the first not work whereas last 2 will. in case because pm not valid in fr-fr. if try this:

datetime.parseexact(@"14/04/2010 10:14:49.", @"dd/mm/yyyy hh:mm:ss.tt", new cultureinfo("fr-fr")) 

it work fine.

as has been noted in comments other cultures may fail on other items. en-za uses different date separator causing fail.
