Stack.Pop() Method in C# Last Updated : 11 Jul, 2025 Comments Improve Suggest changes Like Article Like Report This method(comes under System.Collections namespace) is used to remove and returns the object at the top of the Stack. This method is similar to the Peek method, but Peek does not modify the Stack. Syntax: public virtual object Pop (); Return Value: It returns the Object removed from the top of the Stack. Exception : This method will give InvalidOperationException if the Stack is empty. Below programs illustrate the use of the above-discussed method: Example 1: csharp // C# Program to illustrate the // use of Stack.Pop() Method using System; using System.Collections; class GFG { // Main Method public static void Main() { // Creating a Stack Stack myStack = new Stack(); // Inserting the elements into the Stack myStack.Push("Geeks"); myStack.Push("Geeks Classes"); myStack.Push("Noida"); myStack.Push("Data Structures"); myStack.Push("GeeksforGeeks"); Console.WriteLine("Number of elements in the Stack: {0}", myStack.Count); // Retrieveing top element of Stack Console.Write("Top element of Stack is: "); Console.Write(myStack.Pop()); // printing the no of Stack element // after Pop operation Console.WriteLine("\nNumber of elements in the Stack: {0}", myStack.Count); } } Output: Number of elements in the Stack: 5 Top element of Stack is: GeeksforGeeks Number of elements in the Stack: 4 Example 2: csharp // C# Program to illustrate the // use of Stack.Pop() Method using System; using System.Collections; class GFG { // Main Method public static void Main() { // Creating a Stack Stack myStack = new Stack(); // Inserting the elements into the Stack myStack.Push(7); myStack.Push(9); Console.WriteLine("Number of elements in the Stack: {0}", myStack.Count); // Retrieveing top element of Stack Console.Write("Top element of Stack is: "); Console.Write(myStack.Pop()); // printing the no of Stack element // after Pop operation Console.WriteLine("\nNumber of elements in the Stack: {0}", myStack.Count); } } Output: Number of elements in the Stack: 2 Top element of Stack is: 9 Number of elements in the Stack: 1 Reference: https://learn.microsoft.com/en-us/dotnet/api/system.collections.stack.pop?view=netframework-4.7.2 Create Quiz Comment K Kirti_Mangal Follow 0 Improve K Kirti_Mangal Follow 0 Improve Article Tags : C# CSharp-method CSharp-Collections-Namespace CSharp-Collections-Stack Explore IntroductionC# Tutorial 2 min read Introduction to .NET Framework 6 min read C# .NET Framework (Basic Architecture and Component Stack) 6 min read C# Hello World 2 min read Common Language Runtime (CLR) in C# 4 min read FundamentalsC# Identifiers 2 min read Data Types in C# 6 min read C# Variables 4 min read C# Literals 5 min read Operators in C# 7 min read C# Keywords 5 min read Control StatementsC# Decision Making (if, if-else, if-else-if ladder, nested if, switch, nested switch) 5 min read C# Switch Statement 4 min read Loops in C# 4 min read C# Jump Statements (Break, Continue, Goto, Return and Throw) 4 min read OOP ConceptsClass and Objects in C# 4 min read Constructors in C# 5 min read C# Inheritance 3 min read Encapsulation in C# 2 min read C# Abstraction 4 min read MethodsMethods in C# 4 min read Method Overloading in C# 4 min read Method Parameters in C# 4 min read Method Overriding in C# 7 min read Anonymous Method in C# 2 min read ArraysArrays in C# 6 min read Jagged Arrays in C# 4 min read Array Class in C# 5 min read How to Sort an Array in C# | Array.Sort() Method Set - 1 8 min read How to find the rank of an array in C# 2 min read ArrayListArrayList in C# 6 min read ArrayList Class in C# 4 min read C# | Array vs ArrayList 2 min read StringStrings in C# 6 min read C# Verbatim String Literal - @ 5 min read C# String Class 9 min read C# StringBuilder 2 min read C# String vs StringBuilder 3 min read TupleC# Tuple 7 min read C# Tuple Class 3 min read C# ValueTuple 7 min read C# ValueTuple Struct 4 min read IndexersC# Indexers 5 min read C# Multidimensional Indexers 5 min read C# - Overloading of Indexers 3 min read Like
