Cannot convert string using DateTime.TryParseExact in machine with non English culture.

I am having a problem converting a string "21-11-2013 0:00:00" to its DateTime equivalent in my ASPX page (happens when tested with Windows XP (Dutch language))  .
This string is the default current date returned by the SQL reporting server. 
System.Globalization.CultureInfo.CurrentUICulture.DateTimeFormat.ShortDatePattern = dd-MM-yyyy. 
DateTime.TryParseExact("21-11-2013 0:00:00", System.Globalization.CultureInfo.CurrentUICulture.DateTimeFormat.ShortDatePattern, null, System.Globalization.DateTimeStyles.None, out parsedDate) The code above returns False. 
Is there a way to convert the string (which can be in any format depending on the regional settings of the computer) correctly? 
Thank you.
