ArrayList - Move Item

[Andrew Neillans]

Hi all,

I have arraylist that contains a series of objects - I need to move one
object to another location in the list. What is the most efficient way
of doing this?

e.g.
ArrayList:
Item1
Item2
Item3

Move Item2 to the last position giving:

ArrayList:
Item1
Item3
Item2

Regards,

Andy Neillans

Why don't you start with the easiest way and see if it's efficient
enough for you? Something like

object item = yourArrayList[idx];
yourArrayList.RemoveAt(idx);
yourArrayList.Insert(newIdx, item);
