Check if a value is in LinkedList in C#

To check if a value is in LinkedList, try the below code −

Example

 Live Demo

using System;
using System.Collections.Generic;
public class Demo {
   public static void Main(){
      LinkedList<int> linkedList = new LinkedList<int>();
      linkedList.AddLast(25);
      linkedList.AddLast(50);
      linkedList.AddLast(100);
      linkedList.AddLast(200);
      linkedList.AddLast(400);
      linkedList.AddLast(500);
      linkedList.AddLast(550);
      linkedList.AddLast(600);
      linkedList.AddLast(800);
      linkedList.AddLast(1200);
      Console.WriteLine("Count of nodes = " + linkedList.Count);
      foreach(int val in linkedList){
         Console.WriteLine(val);
      }
      Console.WriteLine("Does the LinkedList has node 800? "+linkedList.Contains(800));
   }
}

Output

This will produce the following output −

Count of nodes = 10
25
50
100
200
400
500
550
600
800
1200
Does the LinkedList has node 800? True

Example

Let us see another example −

 Live Demo

using System;
using System.Collections.Generic;
public class Demo {
   public static void Main(){
      LinkedList<string> linkedList = new LinkedList<string>();
      linkedList.AddLast("ABC");
      linkedList.AddLast("BCD");
      linkedList.AddLast("CDE");
      linkedList.AddLast("DEF");
      linkedList.AddLast("EFG");
      linkedList.AddLast("FGH");
      linkedList.AddLast("GHI");
      linkedList.AddLast("HIJ");
      linkedList.AddLast("IJK");
      Console.WriteLine("Count of nodes = " + linkedList.Count);
      foreach(string val in linkedList){
         Console.WriteLine(val);
      }
      Console.WriteLine("Does the LinkedList has node KLM? "+linkedList.Contains("KLM"));
   }
}

Output

This will produce the following output −

Count of nodes = 9
ABC
BCD
CDE
DEF
EFG
FGH
GHI
HIJ
IJK
Does the LinkedList has node KLM? False
