C# | Removing all nodes from LinkedList<T> Last Updated : 11 Jul, 2025 Comments Improve Suggest changes Like Article Like Report LinkedList<T>.Clear method is used to remove the all nodes from the LinkedList<T>. Syntax: public void Clear (); Below given are some examples to understand the implementation in a better way: Example 1: CSHARP // C# code to remove all // nodes from LinkedList using System; using System.Collections; using System.Collections.Generic; class GFG { // Driver code public static void Main() { // Creating a LinkedList of Strings LinkedList<String> myList = new LinkedList<String>(); // Adding nodes in LinkedList myList.AddLast("A"); myList.AddLast("B"); myList.AddLast("C"); myList.AddLast("D"); myList.AddLast("E"); // To get the count of nodes in LinkedList // before removing all the nodes Console.WriteLine("Total nodes in myList are : " + myList.Count); // Removing all nodes from LinkedList myList.Clear(); // To get the count of nodes in LinkedList // after removing all the nodes Console.WriteLine("Total nodes in myList are : " + myList.Count); } } Output: Total nodes in myList are : 5 Total nodes in myList are : 0 Example 2: CSHARP // C# code to remove all // nodes from LinkedList using System; using System.Collections; using System.Collections.Generic; class GFG { // Driver code public static void Main() { // Creating a LinkedList of Integers LinkedList<int> myList = new LinkedList<int>(); // Adding nodes in LinkedList myList.AddLast(2); myList.AddLast(4); myList.AddLast(6); // To get the count of nodes in LinkedList // before removing all the nodes Console.WriteLine("Total nodes in myList are : " + myList.Count); // Removing all nodes from LinkedList myList.Clear(); // To get the count of nodes in LinkedList // after removing all the nodes Console.WriteLine("Total nodes in myList are : " + myList.Count); } } Output: Total nodes in myList are : 3 Total nodes in myList are : 0 Note: 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.
