问题：String was not recognized as a valid DateTime

Console.WriteLine("Date is {0}",DateTime.Parse("11/3/2005 10:29:41 AM"));
Console.WriteLine("Date is {0}",DateTime.Parse("27/03/2005 10:46:02 AM"));

        

输出的结果：

Date is 2005-11-3 10:29:41
String was not recognized as a valid DateTime

系统认为27为月份了，所以转换失败。

解决：

Console.WriteLine("Date is {0}",DateTime.ParseExact("27/03/2005 10:46:02 AM","dd/MM/yyyy HH:mm:ss tt",System.Globalization.CultureInfo.InvariantCulture));

输出：

2005-3-27 10:46:02
