Question

I know this is probably a pretty simple question, but i am trying to write a function that returns a bool value of “true” if a date passed is in the future, like this:

bool IsFutureDate(System.DateTime refDate)
{
    if (refDate > DateTime.Now)  // This doesn't seem to work
        return true;
    return false;
}

Anyone tell me who to write a function like this that actually works?

Thanks

The only thing I can think of is you might get undefined behaviour if refDate == today.

DateTime.Now includes the time. If refDate if for say today at 3:00 and you run it at 2:00 it will return true. If you run at 4:00 it will return false.

Compare it to DateTime.Today and that will just return the date, preventing the time of day influencing it.

Other than that it should all be fine..
