Check if a value is in LinkedList in C#
To check if a value is in LinkedList, try the below code −
Example
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 −
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
