i have a string which contains date time this...
string S="08/18/2013 24:00:00"
DateTime DT = DateTime.ParseExact(S, "MM/dd/yyyy HH:mm:ss", null);
i want to parse it into date time but shows an exception like this. The DateTime represented by the string is not supported in calendar System.Globalization.GregorianCalendar.
please tell me any solution for this problem.
The problem is with the hour being 24. DateTime doesn't support this, as far as I'm aware.
Options:
DateTime, manually replace "24:00:00" with "00:00:00" when it occurs, and remember to add a day afterwardsIf you want to preserve the information that it was actually "end of the day" you'd need to do that separately, and keep the information alongside the DateTime / LocalDateTime.
You should also parse with the invariant culture as other answers have suggested - you're not trying to parse a culture-specific string; you know the exact separators etc.
string S="08/18/2013 00:00:00"; // here is the first problem occurred
DateTime DT = DateTime.ParseExact(S, "MM/dd/yyyy hh:mm:ss", System.Globalization.CultureInfo.InvariantCulture);
From The "HH" Custom Format Specifier
The "HH" custom format specifier (plus any number of additional "H" specifiers) represents the hour as a number from 00 through 23; that is, the hour is represented by a zero-based 24-hour clock that counts the hours since midnight.
So, using 24 as an hour is invalid on this case.
Try with hh format with 00 instead like;
string S = "08/18/2013 00:00:00";
DateTime DT = DateTime.ParseExact(S, "MM/dd/yyyy hh:mm:ss", CultureInfo.InvariantCulture);
Here a DEMO.
If you really want to use 24:00:00 as a hour, take a look Noda Time which developed by Jon.
