Iterating through collections without For and Foreach using IEnumerable and IEnumerator

We were using a number of collections holding same type of data. Someone asked me if there is a way to handle these collections in a common way. In other words how do we iterate through different kinds of collection using a common function .I told them we could achieve the same using  a function with IEnumerable<T>  . I demonstrated the same using 3 collections Generic Stack, Queue, and Ordered List.

Following is the code snippet that demonstrates the same

using System;

using System.Collections.Generic;

using System.Collections;

namespace testCollection

{

    class Program

    {

        static void Main(string[] args)

        {

            //Stack of integers

            Stack<int> stackCollection = new Stack<int>();

            stackCollection.Push(1);

            stackCollection.Push(2);

            stackCollection.Push(3);

            stackCollection.Push(4);

            stackCollection.Push(5);

            //Queue of Integers

            Queue<int> queueCollection = new Queue<int>();

            queueCollection.Enqueue(1);

            queueCollection.Enqueue(2);

            queueCollection.Enqueue(3);

            queueCollection.Enqueue(4);

            queueCollection.Enqueue(5);

            //ordered list of integers

            List<int> listCollection = new List<int>();

            listCollection.Add(1);

            listCollection.Add(2);

            listCollection.Add(3);

            listCollection.Add(4);

            listCollection.Add(5);

            //iterates through the stack of items in last in first out manner

            GetItems(stackCollection);

            //iterates through the queue in a fist in first out  manner

            GetItems(queueCollection);

            //Iterates through an ordered list of integers

            GetItems(listCollection);

            Console.ReadLine();

        }

        /// <summary>

        /// generic iteration logic for a collection

        /// </summary >

        /// <param name="collection"> is decided at runtime and instance of a class implementing ienumerable</param>

        public static void GetItems(IEnumerable<int> collection)

        {

            //gets the enumerator

            IEnumerator<int> enumerator = collection.GetEnumerator();

            while (enumerator.MoveNext ())

            {

                //gets the items from the collection

                Console.WriteLine(enumerator.Current);  

            }

        }

    }

}
