ASP.NET C＃字符串为DateTime愁楚

Question

这是要健全挺无聊的，但我不能让一个字符串转换成承载我试试这个日期和时间

一个DateTime：

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，它不是一个可表示的DateTime。这里同样的事情。

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

我有这么多麻烦。我如何正确地做到这一点？

Answer 1

我觉得你的问题是在这里

+ minute + " 00 " + "AM" 

应该是：

+ minute + ":00 " + "AM"
