Program to check element is exist in Queue or not in C#

using System;
using System.Collections;

namespace ConsoleApplication1
{
    
    class Program
    {
        static void Main()
        {
            Queue Q = new Queue(5);

            Q.Enqueue(10);
            Q.Enqueue(20);
            Q.Enqueue(30);
            Q.Enqueue(40);

            if (Q.Contains(30))
                Console.WriteLine("Item exists in queue");
            else
                Console.WriteLine("Item does not exist in queue");

        }
    }
}

Output

Item exists in queue.

In this program, we are inserting 4 elements (10,20,30,40) in Queue, and then checking item 30 is exist in Queue or not using Contains() method of Queue class.

Note: In above program, to use 'Queue' class, we need to include System.Collection namespace.
