Check whether a node is in a Linked List or not

Answer»

To check whether a node is in a Linked List or not, the best way is to use the Contains() method.

The Contains() method has a parameter that is the value you are SEARCHING for in a Linked List:

Contains(Value)

The method RETURNS a Boolean Value. If a node is found in the Linked List, TRUE is returned.

Let us see an example:

using System; using System.Collections.Generic; CLASS Demo {    static VOID Main()    {        string [] devices = {"Smartphones","Smartwatches"};        LinkedList<string> myList = new LinkedList<string>(devices);                         foreach (var d in myList)          {            Console.WriteLine(d);          }        Console.WriteLine("Smartphones in the list?: "+myList.Contains("Smartphones"));    } }

The OUTPUT:

Smartphones Smartwatches Smartphones in the list?: True
