Stack.Count Property in C#

The Stack.Count property in C# is used to get the number of elements contained in the Stack.

Syntax

The syntax is as follows −

public virtual int Count { get; }

Example

Let us now see an example −

 Live Demo

using System;
using System.Collections;
public class Demo {
   public static void Main() {
      Stack stack = new Stack();
      stack.Push("Inspiron");
      stack.Push("Alienware");
      stack.Push("Projectors");
      stack.Push("Monitors");
      stack.Push("XPS");
      stack.Push("Laptop");
      stack.Push("Notebook");
      Console.WriteLine("Stack elements...");
      foreach(string val in stack) {
         Console.WriteLine(val);
      }
      Console.WriteLine("Count of elements = "+stack.Count);
      stack.Push("Ultrabook");
      stack.Push("Cameras");
      stack.Push("Keyboards");
      Console.WriteLine("
Stack elements...updated");
      foreach(string val in stack) {
         Console.WriteLine(val);
      }
      Console.WriteLine("
Count of elements (updated) = "+stack.Count);
      stack.Clear();
      Console.Write("Count of elements (updated) = "+stack.Count);
   }
}

Output

This will produce the following output −

Stack elements...
Notebook
Laptop
XPS
Monitors
Projectors
Alienware
Inspiron
Count of elements = 7
Stack elements...updated
Keyboards
Cameras
Ultrabook
Notebook
Laptop
XPS
Monitors
Projectors
Alienware
Inspiron
Count of elements (updated) = 10
Count of elements (updated) = 0

Example

Let us now see another example −

 Live Demo

using System;
using System.Collections;
public class Demo {
   public static void Main() {
      Stack stack = new Stack();
      stack.Push(150);
      stack.Push(300);
      stack.Push(500);
      stack.Push(750);
      stack.Push(1000);
      stack.Push(1250);
      stack.Push(1500);
      stack.Push(2000);
      stack.Push(2500);
      Console.WriteLine("Stack elements...");
      foreach(int val in stack) {
         Console.WriteLine(val);
      }
      Console.WriteLine("Count of elements = "+stack.Count);
      stack.Push(3000);
      stack.Push(3500);
      stack.Push(4000);
      Console.WriteLine("
Stack elements...updated");
      foreach(int val in stack) {
         Console.WriteLine(val);
      }
      Console.WriteLine("
Count of elements (updated) = "+stack.Count);
      stack.Clear();
      Console.Write("Count of elements (updated) = "+stack.Count);
   }
}

Output

This will produce the following output −

Stack elements...
2500
2000
1500
1250
1000
750
500
300
150
Count of elements = 9
Stack elements...updated
4000
3500
3000
2500
2000
1500
1250
1000
750
500
300
150
Count of elements (updated) = 12
Count of elements (updated) = 0
