LinkedList<T>.Remove Method (LinkedListNode<T>)

Removes the specified node from the LinkedList<T>.

Namespace:  System.Collections.Generic
Assembly:  System (in System.dll)

public void Remove(
	LinkedListNode<T> node
)

ExceptionCondition
ArgumentNullException

node is null.

InvalidOperationException

node is not in the current LinkedList<T>.

This method is an O(1) operation.

The following code example and output demonstrate the Remove method. The code example begins by marking the existing node "fox". The code then finds the node containing "dog" and attempts to add "fox" before "dog" without first removing "fox" from the list. This causes an InvalidOperationException, which is caught. The code example then uses the Remove(LinkedListNode<T>) method overload to remove the node containing "fox" from the list, and then adds "fox" before "dog". Finally, the code example uses the Remove(LinkedListNode<T>) method overload to remove the node containing "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.


// Remove the node referred to by mark1, and then add it
// before the node referred to by current.
// Indicate the node referred to by current.
sentence.Remove(mark1);
sentence.AddBefore(current, mark1);
