Question

Answer 1

+3 A:

int result = int.Parse(myDate.ToString("yyyyMMdd"));

+1, I would just add you might want to do a TryParse, just to be safe.

so it is required to first convert the DateTime to a string, then to an int? Thanks for your code, i was unaware of int.Parse

@Phillis: No, it's not required. But above code shows better what exactly is going on, though.

@JackM - This would be a rare case where TryParse is unnecessary as there is no way the format string will ever result in a non-integer.

Yes - here you KNOW the format, in advance, so it's safe to avoid. Johannes's answer is better, though.

Answer 2

+9 A:

int x = date.Year * 10000 + date.Month * 100 + date.Day

+1 Creative solution to avoid parsing the string.

Steve Danner 2010-02-03 22:36:39

@Steve: Well, the most straightforward that came to my mind ;). The format string variant just makes things a little clearer for someone only casually glancing at the code.

Joey 2010-02-03 22:38:28

Nice option for this. Very clean way to handle it.
