LinkedList<T>.Clear Method

Removes all nodes from the LinkedList<T>.

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

public void Clear()

Implements

ICollection<T>.Clear()

Count is set to zero, and references to other objects from elements of the collection are also released. First and Last are set to null.

This method is an O(n) operation, where n is Count.

The following code example and output demonstrate the Clear method. The code example creates an array the same size as the linked list, copies the values of all the nodes to the string array beginning at element 0 of the array, and then uses the Clear method to clear the array.

This code and output are part of a larger example provided for the LinkedList<T> class.

// Release all the nodes.
sentence.Clear();

Console.WriteLine();
Console.WriteLine("Test 17: Clear linked list. Contains 'jumped' = {0}",
    sentence.Contains("jumped"));
