Short way to add item after item in List?

Question

If there any short way besides foreach loop and new collection creation to add object after specific object in existing List ?

Just an example:

"amy","jerry","tony","amy","jack". I want to add "simon" after each "amy" in short way

Answer 1

If you know where you want to enter an item, you can do

List.Insert(position, item)

See List.Insert() on MSDN
