Datetime.parseexact抛出错误

Question

我有以下代码

inputdatetime值为"2014/09/11 8:06 AM" dateformat是"yyyy/MM/dd h:mm a"

CultureInfo culture = CultureInfo.InvariantCulture;

string dateforamat = string.Concat(date, " ", time);

returnValue = DateTime.ParseExact(inputDateTime, dateforamat, culture);

我收到格式异常

Answer 1

使用tt代替a

DateTime.ParseExact("2014/09/11 8:06 AM", "yyyy/MM/dd h:mm tt", CultureInfo.InvariantCulture);
