One would think the simple code

llist1.Last.Next = llist2.First;
llist2.First.Previous = llist1.Last;

would work, however apparently in C#'s LinkedList, First, Last, and their properties are Get only.

The other method I could think of was

llist1.AddLast(llist2.First);

However, this does not work either - it fails because the first node of llist2 is already in a linked list.

Does this mean that I have to have a loop that manually AddLast's each node of llist2 to llist1? Doesn't this defeat the efficiency of linked lists????
