LinkedList<T>.Clear method is used to remove the all nodes from the LinkedList<T>.
Syntax:
CSHARP
Output:
CSHARP
public void Clear ();Below given are some examples to understand the implementation in a better way: Example 1:
// 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);
}
}
Total nodes in myList are : 5 Total nodes in myList are : 0Example 2:
// 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 : 0Note:
- 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.
