So I have a generic list, and an oldIndex and a newIndex value.
I want to move the item at oldIndex, to newIndex.
I would expect either:
// Makes sure item is at newIndex after the operation
T item = list[oldIndex];
list.RemoveAt(oldIndex);
list.Insert(newIndex, item);
... or:
// Makes sure relative ordering of newIndex is preserved after the operation,
// meaning that the item may actually be inserted at newIndex - 1
T item = list[oldIndex];
list.RemoveAt(oldIndex);
newIndex = (newIndex > oldIndex ? newIndex - 1, newIndex)
list.Insert(newIndex, item);
... would do the trick, but I don't have VS on this machine to check.
