DateTime.ParseExact() does not grok 24-hour time values?

Question

This line of code:

DateTime dt = DateTime.ParseExact(time, "hh:mm", CultureInfo.InvariantCulture);

parses a "time" value of "12:45" just fine, but throws an exception of "13:00"

Should I be using some other CultureInfo value, or do I need to append a "pm" to hour values above 12, or ... ?

Error message is: System.FormatException was unhandled Message=String was not recognized as a valid DateTime.

Use "HH:mm" to parse 24 hour formats. – Hans Passant Jun 27 '12 at 18:06 — Hans Passant, Jun 27 '12 at 18:06
+1 for using the term "grok" in an SO question – Aran Mulholland Dec 02 '13 at 05:58 — Aran Mulholland, Dec 02 '13 at 05:58

"hh" is the 12-hour clock format (01 to 12). You need to use "HH" for a 24 hour clock.

DateTime dt = DateTime.ParseExact(time, "HH:mm", CultureInfo.InvariantCulture);

Try this:

DateTime dt = DateTime.ParseExact(time, "u", CultureInfo.InvariantCulture);

"u" indicates universal sortable format.
