无法将String转换为DateTIme

Question

My Date Format : 12/30/2014 12:00:00 AM (MM/dd/yyyy) and I have a string rep as

String DateOfIssue = "12/30/2014 12:00:00 AM";

DateTime DOI = DateTime.ParseExact((DateOfIssue).Trim(), "MM/dd/yyyy HH:mm:ss tt", CultureInfo.GetCultureInfo("en-GB"));

but it is throwing exception. I have seen a lot of posts on SO but none is working. What am I doing wrong ? Please help and point my error. I have tried en-US also but that is also not working.

when I remove tt every thing works fine.

Answer 1

HH -为24小时格式，请使用hh代替：

DateTime DOI = DateTime.ParseExact((DateOfIssue).Trim(), "MM/dd/yyyy hh:mm:ss tt", CultureInfo.GetCultureInfo("en-GB"));
