Question

So, here’s the scenario. I have a file with a created time, and I want to choose a time from a list of times that that file’s created time is closest or equal too…what would be the best way to accomplish this?

Answer 1

Something like this:

DateTime fileDate, closestDate;
ArrayList theDates;
long min = long.MaxValue;

foreach (DateTime date in theDates)
 if (Math.Abs(date.Ticks - fileDate.Ticks) < min)
 {
   min = Math.Abs(date.Ticks - fileDate.Ticks);
   closestDate = date;
 }
