DateTime Problem

string var = DateTime.Today. Month.ToString( ) + "-" +
DateTime.Today. Day.ToString() + "-" + DateTime.Today. Year.ToString() + "-" +
DateTime.Today. Hour.ToString() + "-" + DateTime.Today. Minute.ToString () +
"-" + DateTime.Today. Second.ToString ();
MessageBox.Show (var);

returns 12-21-2006-0-0-0

Why would the hours, minute and second not appear correctly?

Using DateTime.Now works. I overlooked Now.

The hours, minute and second appear absolutely correctly because
DateTime.Today returns a DateTime object with just the date, i.e. the time
part all set to 0 (midnight).

Have a look at The DateTime.ToStri ng(format) overloads to make life easier
for yourself.

MessageBox.Show (DateTime.Today .ToString("M-d-y-H-m-s")) and
MessageBox.Show (DateTime.Now.T oString("M-d-y-H-m-s"))

will display:

12-21-2006-0-0-0 and
12-21-2006-12-34-56

respectively if the time is 12:34:56 PM on 21/12/2006.

I realise that the problem is resolved, but can I offer some advice?
Either use the format specifiers, or cache the date first, otherwise
you could get anomolies if (for instance) the date ticks over midnight
between calls... and on newyear you could end up printing dates a year
in the future... as in:
[end of 2006]
var = (Dec) + (12)...
[<tick, fireworks, etcnow January]
...+(2007)+(0)+ (0)+(0)

i.e.
DateTime when = DateTime.Now;
and work with "when"; the overloads on .ToString() are good too, but
already mentioned by another poster.
