OrderBy().Last() or OrderByDescending().First() performance
.net, c#, linq
Solution
Assuming that both ways of sorting take equal time (and that's a big 'if'), then the first method would have the extra cost of doing a `.Last()`, potentially requiring a full enumeration.
And that argument probably holds even stronger for an SQL oriented LINQ.
Problem
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.Created).Last(); ``` or ``` var lastObject = myList.OrderByDescending(item => item.Created).First(); ``` I am looking for answers for Linq to objects and Linq to Entities.
