如何转换以下字符串

    20/11/2011 3:40:55 am

进入C＃DateTime？

Answer 1

使用DateTime.ParseExact。

string dateString = "20/11/2011 3:40:55 am";
DateTime parsedDate = DateTime.ParseExact(
   dateString,
   "dd/MM/yyyy h:mm:ss tt",
   CultureInfo.InvariantCulture);

例如：

string dateString = "5/1/2008 8:30:52 AM";
DateTime date1 = DateTime.Parse(dateString, 
                          System.Globalization.CultureInfo.InvariantCulture); 

Answer 3

DateTime DT_1 = new DateTime(2011, 11, 9, 21, 40, 55);
DateTime DT_2 = new DateTime(2011, 11, 20, 15, 40, 55);
