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
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
