LinkedList.Clear Method

Removes all nodes from the LinkedList.

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

public void Clear ()
public final void Clear ()
public final function Clear ()
Not applicable.

Count is set to zero, and references to other objects from elements of the collection are also released. First and Last are set to a null reference (Nothing in Visual Basic).

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 class.

// Create an array with the same number of
// elements as the inked list.
string[] sArray = new string[sentence.Count];
sentence.CopyTo(sArray, 0);

foreach (string s in sArray)
