Question

I have some data coming from an XML document, such as 2012-12-06T24:00.

The problem is when I try to convert it : 24:00 doesnt exist. So :

DateTime.Parse(myDateTimeString).Hour

give to me this Exception: System.FormatException: The DateTime represented by the string is not supported in calendar System.Globalization.GregorianCalendar.

How can I fix it?

The solution I think about is to replace (string) T24 with T00, which looks horrible…

Answer 1

DateTime cannot handle this. You have to “sanitize” your string before calling Parse and handle the overflow (depending on what “24:00” actually means):

DateTime date = DateTime.Parse(myDateTimeString.Replace("T24:00", "T00:00"));

if (myDateTimeString.Contains("T24:00"))
{
    date = date.AddDays(1);
}

EDIT: added the “overflow”-part.
