string[] dateStrings = {"05/01/2009 14:57:32.8", "2009-05-01 14:57:32.8", 
                        "2009-05-01T14:57:32.8375298-04:00", 
                        "5/01/2008 14:57:32.80 -07:00", 
                        "1 May 2008 2:57:32.8 PM", "16-05-2009 1:00:32 PM", 
                        "Fri, 15 May 2009 20:10:57 GMT" };
DateTime dateValue;

Console.WriteLine("Attempting to parse strings using {0} culture.", 
                  CultureInfo.CurrentCulture.Name);
foreach (string dateString in dateStrings)
{
   if (DateTime.TryParse(dateString, out dateValue)) 
      Console.WriteLine("  Converted '{0}' to {1} ({2}).", dateString, 
                        dateValue, dateValue.Kind);
   else
      Console.WriteLine("  Unable to parse '{0}'.", dateString);
