Stack.Clone() Method in C# Last Updated : 05 Feb, 2019 Comments Improve Suggest changes Like Article Like Report This method is used to create a shallow copy of the Stack. It just creates a copy of the Stack. The copy will have a reference to a clone of the internal data array but not a reference to the original internal data array. Syntax: public virtual object Clone (); Return Value: The method returns an Object which is just the shallow copy of the Stack. Example 1: Let's see an example without using a Clone() method and directly copying a Stack using assignment operator '='. In the below code, we can see even if we Pop() elements from myStack2, contents of myStack is also changed. This is because '=' just assigns the reference of myStack to myStack2 and does not create any new Stack. But Clone() creates a new Stack. csharp // C# program to Copy a Stack using // the assignment operator using System; using System.Collections; class GFG { // Main Method public static void Main(string[] args) { Stack myStack = new Stack(); myStack.Push("C"); myStack.Push("C++"); myStack.Push("Java"); myStack.Push("C#"); // Creating a copy using the // assignment operator. Stack myStack2 = myStack; // Removing top most element myStack2.Pop(); PrintValues(myStack); } public static void PrintValues(IEnumerable myCollection) { // This method prints all // the elements in the Stack. foreach(Object obj in myCollection) Console.WriteLine(obj); } } Output: Java C++ C Example 2: csharp // C# program to illustrate the use // of Stack.Clone() Method using System; using System.Collections; class MainClass { // Main Method public static void Main(string[] args) { Stack myStack = new Stack(); myStack.Push("1st Element"); myStack.Push("2nd Element"); myStack.Push("3rd Element"); myStack.Push("4th Element"); // Creating copy using Clone() method Stack myStack3 = (Stack)myStack.Clone(); // Removing top most element myStack3.Pop(); PrintValues(myStack); } public static void PrintValues(IEnumerable myCollection) { // This method prints all the // elements in the Stack. foreach(Object obj in myCollection) Console.WriteLine(obj); } } Output: 4th Element 3rd Element 2nd Element 1st Element Reference: https://docs.microsoft.com/en-us/dotnet/api/system.collections.stack.clone?view=netframework-4.7.2#System_Collections_Stack_Clone Comment More infoAdvertise with us Next Article Stack.Contains() Method in C# M mayukh Sengupta Follow Improve Article Tags : C# C# Programs Similar Reads C# Stack Class In C#, the Stack<T> class represents a Last-in-First-out (LIFO) collection of objects.

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.
