LinkedList<T>.AddBefore Method (LinkedListNode<T>, LinkedListNode<T>)
Adds the specified new node before the specified existing node in the LinkedList<T>.
Assembly: System (in System.dll)
The following code example and output demonstrate the AddBefore method. The code example begins by marking the existing node containing "fox". The code then finds the node containing "dog" and attempts to use the method overload to add "fox" before "dog", without first removing "fox" from the list. This causes an InvalidOperationException, which is caught. The code example then removes "fox" and uses the method overload to add it before "dog". Finally, the code example removes "dog" and inserts it at the location formerly occupied by "fox".
This code and output are part of a larger example provided for the LinkedList<T> class.
