Exploring LinQ

LinQ is very powerfull, really really powerfull.

Referring to my last post (LinQ: Max() vs OrderBy()-FirstOrDefault()) here is a similar example:

var i = (from item in listOfItems
where item.Size = listOfItems.Max(i => i.Size)
select item);

What about performance ?
What about that “listOfItems.Max(i => i.Size)” ?
Will be executed every iteration, or cached before cycle ?
Reflector may help you exploring the code LinQ is compiled in.

Dustin Campbell had same idea, with this post. 😉
