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
