Stack.Count Property in C#

  • Last Updated : 04 Feb, 2019

This method(comes under System.Collections namespace) is used to get the number of elements contained in the Stack. The capacity is the number of elements that the Stack can store and the count is the number of elements that are actually in the Stack. The capacity is always greater than or equal to Count. Retrieving the value of this property is an O(1) operation.

Syntax:

public virtual int Count { get; }

Return Value: It returns the number of elements contained in the Stack having type System.Int32.

Below programs illustrate the use of above-discussed property:

Example 1:






// C# code illustrate the
// Stack.Count Property
using System;
using System.Collections;
  
class GFG {
  
    // Driver code
    public static void Main()
    {
  
        // Creating a Stack
        Stack myStack = new Stack();
  
        // Inserting the elements into the Stack
        myStack.Push("Chandigarh");
        myStack.Push("Delhi");
        myStack.Push("Noida");
        myStack.Push("Himachal");
        myStack.Push("Punjab");
        myStack.Push("Jammu");
  
        // Displaying the count of elements
        // contained in the Stack
        Console.Write("Total number of elements"+
                         " in the Stack are : ");
  
        Console.WriteLine(myStack.Count);
    }
}
Output:
Total number of elements in the Stack are : 6

Example 2:




// C# code illustrate the
// Stack.Count Property
using System;
using System.Collections;
  
class GFG {
  
    // Driver code
    public static void Main()
    {
  
        // Creating a Stack
        Stack myStack = new Stack();
  
        // Displaying the count of elements
        // contained in the Stack
        Console.Write("Total number of elements"+
                         " in the Stack are : ");
  
        // The function should return 0
        // as the Stack is empty and it
        // doesn't contain any element
        Console.WriteLine(myStack.Count);
    }
}
Output:
Total number of elements in the Stack are : 0
