I'd use this only because I find 2 lines of code easier to read than all of the others above. var itemsToRemove = oldList.Except(newList).ToArray(); var itemsToAdd = newList.Except(oldList).ToArray();This will work as long as each list is actually a set. Given your description of...

    var itemsToRemove = oldList.Except(newList).ToArray();
    var itemsToAdd = newList.Except(oldList).ToArray();
