Question

I have a collection of items, where each item has these fields: Title, DateCreated, and DateUpdated

I want to order these items so that the most recent items are displayed first, where the most recent item is the one that was just created or update.

So if I created Item2 three seconds ago, it will show up on top. But if I then go update Item1, it will now show up on top, because Item1’s DateUpdated is more recent than Item2’s DateCreated

Is there a way to order a collection this way based on two dates?

Answer 1

var newList = 
      list.OrderByDescending(s=>Math.Max(s.DateCreated.Ticks,s.DateUpdated.Ticks));
