Program to delete an element from a Queue 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);

            Console.WriteLine("Deleted item is: " + Q.Dequeue());
            Console.WriteLine("Deleted item is: " + Q.Dequeue());
            Console.WriteLine("Deleted item is: " + Q.Dequeue());

        }
    }
}

Output

Deleted item is: 10
Deleted item is: 20
Deleted item is: 30

In this program, we are inserting 4 items into Queue, than deleting 3 items from Queue using Dequeue() method.

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