Question

这听起来很傻但我无法将字符串转换为带有日期和时间的DateTime

我试试这个：

Response.Write(year + " " + month + " " + day + " " + hour + " " + min ); 
//prints 2008 9 23 11 59 0 (represents 9/23/2008 11:59 00 AM)
DateTime dt= new DateTime(year , month , day , hour , min , 00);

但它告诉我它不是可表示的DateTime。这里也是一样。

String toParse = "9/23/2008" + " " + hour + ":" + minute + " 00 " + "AM" ;
DateTime dt=  Convert.ToDateTime(toParse);

我遇到了这么多麻烦。我该如何正确地做到这一点？

Answer 1

我认为你的问题在这里

 + minute + " 00 " + "AM"

应该是：

 + minute + ":00 " + "AM"
