C# | Get the number of elements contained in the Stack

Last Updated : 01 Feb, 2019

Stack represents a last-in, first out collection of object. Stack<T>.Count Property is used to gets the number of elements contained in the Stack. Retrieving the value of this property is an O(1) operation. Syntax:

myStack.Count

Here myStack is the name of the Stack<T> Return Value: The property returns the number of elements contained in the Stack<T>. Example 1:

CSHARP

// C# code to Get the number of
// elements contained in the Stack
using System;
using System.Collections.Generic;

class GFG {

    // Driver code
    public static void Main()
    {

        // Creating a Stack of strings
        Stack<string> myStack = new Stack<string>();

        // 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:

CSHARP

// C# code to Get the number of
// elements contained in the Stack
using System;
using System.Collections.Generic;

class GFG {

    // Driver code
    public static void Main()
    {

        // Creating a Stack of Integers
        Stack<int> myStack = new Stack<int>();

        // 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
