How to create a Stack in C#?

To create a Stack, the code is as follows −

Example

 Live Demo

using System;
using System.Collections.Generic;
public class Demo {
   public static void Main(){
      Stack<int> stack = new Stack<int>();
      stack.Push(100);
      stack.Push(150);
      stack.Push(175);
      stack.Push(200);
      stack.Push(225);
      stack.Push(250);
      stack.Push(300);
      stack.Push(400);
      stack.Push(450);
      stack.Push(500);
      Console.WriteLine("Elements in the Stack:");
      foreach(var val in stack){
         Console.WriteLine(val);
      }
      Console.WriteLine("Count of elements in the Stack = "+stack.Count);
      Console.WriteLine("Does Stack has the element 400?= "+stack.Contains(400));
   }
}

Output

This will produce the following output −

Elements in the Stack:
500
450
400
300
250
225
200
175
150
100
Count of elements in the Stack = 10 Does Stack has the element 400?= True

Example

Let us now see another example −

 Live Demo

using System;
using System.Collections.Generic;
public class Demo {
   public static void Main(){
      Stack<int> stack = new Stack<int>();
      stack.Push(10);
      stack.Push(20);
      stack.Push(30);
      stack.Push(40);
      stack.Push(50);
      stack.Push(60);
      stack.Push(70);
      stack.Push(80);
      stack.Push(90);
      stack.Push(100);
      Console.WriteLine("Count of elements = "+stack.Count);
      Console.WriteLine("Elements in Stack...");
      foreach (int res in stack){
         Console.WriteLine(res);
      }
   }
}

Output

This will produce the following output −

Count of elements = 10
Elements in Stack...
100
90
80
70
60
50
40
30
20
10
