LinkedList Contains Method in C#

Here is our LinkedList.

int [] num = {1, 3, 7, 15}; LinkedList<int> list = new LinkedList<int>(num);

To check whether the list contains an element or not, use the Contains() method. The following example checks for node 3 in the list.

list.Contains(3)

Above, returns True since the element is found as shown below −

Example

 Live Demo

using System; using System.Collections.Generic; class Demo {    static void Main() {       int [] num = {1, 3, 7, 15};       LinkedList<int> list = new LinkedList<int>(num);       foreach (var n in list) {          Console.WriteLine(n);       }       // adding a node at the end       var newNode = list.AddLast(20);       // adding a new node after the node added above       list.AddAfter(newNode, 30);       Console.WriteLine("LinkedList after adding new nodes...");       foreach (var n in list) {          Console.WriteLine(n);       }       Console.WriteLine("Is number 3 (node) in the list?: "+list.Contains(3));    } }

Output

1 3 7 15 LinkedList after adding new nodes... 1 3 7 15 20 30 Is number 3 (node) in the list?: True
