OrderBy().Last() or OrderByDescending().First() performance

Question

I know that this probably is micro-optimization, but still I wonder if there is any difference in using

var lastObject = myList.OrderBy(item => item.Crea         


        

Answer 1

I'm sorry this doesn't directly answer your question, but...

Why not do a better optimization and use Jon Skeet's implementations of MaxBy or MinBy?

That will be O(n) as opposed to O(n log n) in both of the alternatives you presented.
