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);

            Q.Clear();

            Console.WriteLine("All items deleted successfully");

        }
    }
}

Output

All items deleted successfully

In this program, we added 4 items into queue than delete all items using Clear() method.

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