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));
}
