How do ControlCollection.Item(s) work?

Question

Sorry for bad English.

I need to create and manage a large (not that "large"!) number of controls, through the code. I know how to create them and link the events. The issue is the way of future access to added controls.

Which property works better? ControlCollection.Item[int index] or ControlCollection.Item[string key]?

I think that the time complexity of Item[int] must be O(1), and time complexity of Item[string] must be O(n). Is it right?

It could be O(1) by using a hashtable, but it doesn't. – SLaks Mar 12 '12 at 18:53 — SLaks, Mar 12 '12 at 18:53
So, you are saying that both are O(n)? – h.nodehi Mar 12 '12 at 18:56 — h.nodehi, Mar 12 '12 at 18:56

ControlCollection.this[string] is O(n), except that it caches the most-recently-looked-up name.

Thank you, but what is the final answer? Considering all aspects, which one is the **best**? – h.nodehi Mar 12 '12 at 19:03

They do two different things. If you have an index, `this[int]` is obviously better. – SLaks Mar 12 '12 at 19:08
That's like asking "Which is best? A `List` or a `Dictionary`?" – SLaks Mar 12 '12 at 19:09
I meant the least access time by "which is best?". Anyway... Thanks man. – h.nodehi Mar 12 '12 at 19:16
