Stack.ToArray() Method in C# Last Updated : 11 Jul, 2025 Comments Improve Suggest changes 1 Likes Like Report This method(comes under System.Collections namespace) is used to copy a Stack to a new array. The elements are copied onto the array in last-in-first-out (LIFO) order, similar to the order of the elements returned by a succession of calls to Pop. This method is an O(n) operation, where n is Count. Syntax: public virtual object[] ToArray (); Return Type: This method returns a new array of type System.Object containing copies of the elements of the Stack. Below given are some examples to understand the implementation in a better way: Example 1: CSHARP // C# code to illustrate the // Stack.ToArray() Method 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("Geeks"); myStack.Push("Geeks Classes"); myStack.Push("Noida"); myStack.Push("Data Structures"); myStack.Push("GeeksforGeeks"); // Converting the Stack into array Object[] arr = myStack.ToArray(); // Displaying the elements in array foreach(Object str in arr) { Console.WriteLine(str); } } } Output: GeeksforGeeks Data Structures Noida Geeks Classes Geeks Example 2: CSHARP // C# code to illustrate the // Stack.ToArray() Method 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(2); myStack.Push(3); myStack.Push(4); myStack.Push(5); myStack.Push(6); // Converting the Stack into array Object[] arr = myStack.ToArray(); // Displaying the elements in array foreach(Object i in arr) { Console.WriteLine(i); } } } Output: 6 5 4 3 2 Reference: https://learn.microsoft.com/en-us/dotnet/api/system.collections.stack.toarray?view=netframework-4.7.2 Create Quiz Comment K Kirti_Mangal Follow 1 Improve K Kirti_Mangal Follow 1 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
