How do I get the n-th element in a LinkedList?

Question

How can I get the n-th element of a LinkedList instance? Is there a built-in way or I might need to introduce my own implementation? For example an extension method?

Answer 1

The ElementAt extension method will do it:

// This is 0-based of course
var value = linkedList.ElementAt(n);

Don't forget this is an O(n) operation because LinkedList doesn't provide any more efficient way of accessing an item by index. If you need to do this regularly, it suggests that you shouldn't be using a linked list to start with.
