Moving ListViewItems Up & Down

Question

I have a ListView (WinForms) in which i want to move items up and down with the click of a button. The items to be moved are the ones who are checked. So if item 2, 6 and 9 are

Answer 1

Just to complete the @Jason Larkes answer to make it support "move down" properly, add this right before the foreach in the MoveListViewItems function he provided:

ListViewItem[] itemsToBeMoved = sender.SelectedItems.Cast().ToArray(); 
IEnumerable itemsToBeMovedEnum;
if (direction == MoveDirection.Down)
     itemsToBeMovedEnum = itemsToBeMoved.Reverse();
else
     itemsToBeMovedEnum = itemsToBeMoved;

and then iterate using:

foreach (ListViewItem item in itemsTobemovedEnum)

instead of the original foreach.

Works like a charm. @EClaesson - I hope this overcomes the issue you wrote about in the comments.
