C# Stack error

Question

I'm trying to replicate this example from the C# course Generics:

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

q.Enqueue(5);
q.Enqueue(10);
q.Enqueue(15);
Console.Write("Queue: ");
foreach (int i in q)
Console.Write(i + " "); // 5 10 15

And I have the following error:

-foreach statement cannot operate on variables of type 'program.Stack<int>' because 'Program.Stack<int>' does not contain a public instance definition for 'GetEnumerator'-

Answer 1

U need PUBLIC variables. Define them as public, perhaps it'll get over your problem, i hope.

Answer 2

Do you have?
using System.Collections.Generic;
