Clear a stack

using System;
using System.Collections;
class MainClass
{
  static void Main(string[] args)
  {
    Stack a = new Stack(10);
    int x = 0;
    a.Push(x);
    x++;
    a.Push(x);
    foreach (int y in a)
    {
      Console.WriteLine(y);
    }
    a.Pop();
    a.Clear();
  }
}

Pop and Peek

using System;
using System.Collections.Generic;
    public class Tester
    {
        static void Main()
        {
            Stack<Int32> intStack = new Stack<Int32>();
            for (int i = 0; i < 8; i++)
            {
                intStack.Push(i * 5);
            }
            PrintValues(intStack);
            Console.WriteLine("\n(Pop)\t{0}",intStack.Pop());
            PrintValues(intStack);
            Console.WriteLine("\n(Pop)\t{0}",intStack.Pop());
            PrintValues(intStack);
            Console.WriteLine("\n(Peek) \t{0}",intStack.Peek());
            PrintValues(intStack);
            int[] targetArray = new int[12];
            for (int i = 0; i < targetArray.Length; i++)
            {
                targetArray[i] = i * 100 + 100;
            }
            PrintValues(targetArray);
            intStack.CopyTo(targetArray, 6);
            PrintValues(targetArray);
        }
        public static void PrintValues(IEnumerable<Int32> myCollection)
        {
            IEnumerator<Int32> enumerator =myCollection.GetEnumerator();
            while (enumerator.MoveNext())
                Console.Write("{0} ", enumerator.Current);
        }
    }

Push and pop value

using System; 
using System.Collections; 
  
class StackDemo { 
 
 
  public static void Main() { 
    Stack st = new Stack(); 
 
    st.Push(1); 
    st.Push(2); 
    foreach(int i in st) 
      Console.Write(i + " "); 
 
    st.Push(1); 
 
    Console.Write("stack: "); 
    foreach(int i in st) 
      Console.Write(i + " "); 
 
    Console.WriteLine();         

    Console.Write("Pop -> "); 
    int a = (int) st.Pop(); 
    Console.WriteLine(a); 
 
    Console.Write("stack: "); 
    foreach(int i in st) 
      Console.Write(i + " "); 
 
    Console.WriteLine();         
  } 
}

Stack And Queue

using System;
using System.Collections.Generic;
using System.ruponentModel;
    class StackAndQueue
    {
        static void Main()
        {
            Queue<int> queue = new Queue<int>();
            Stack<int> stack = new Stack<int>();
            for (int i = 0; i < 10; i++)
            {
                queue.Enqueue(i);
                stack.Push(i);
            }
            for (int i = 0; i < 10; i++)
            {
                Console.WriteLine("Stack:{0} Queue:{1}",
                                   stack.Pop(), queue.Dequeue());
            }
