Stack.Clone() Method in C#
The Stack.Clone() method in C# is used to create a shallow copy of the Stack.
Syntax
The syntax is as follows −
public virtual object Clone ();
Example
Let us now see an example −
using System; using System.Collections; public class Demo { public static void Main(){ Stack stack = new Stack(); stack.Push(150); stack.Push(300); stack.Push(500); stack.Push(750); stack.Push(1000); stack.Push(1250); stack.Push(1500); stack.Push(2000); stack.Push(2500); Console.WriteLine("Stack elements..."); foreach(int val in stack){ Console.WriteLine(val); } Console.WriteLine("Count of elements = "+stack.Count); stack.Push(3000); stack.Push(3500); stack.Push(4000); Console.WriteLine("
Stack elements...updated"); foreach(int val in stack){ Console.WriteLine(val); } Console.WriteLine("
Count of elements (updated) = "+stack.Count); Stack stack2 = (Stack)stack.Clone(); Console.WriteLine("
Stack elements...cloned"); foreach(int val in stack2){ Console.WriteLine(val); } Console.Write("Count of elements in cloned stack(updated) ="+stack2.Count); } }
Output
This will produce the following output −
Stack elements... 2500 2000 1500 1250 1000 750 500 300 150 Count of elements = 9 Stack elements...updated 4000 3500 3000 2500 2000 1500 1250 1000 750 500 300 150 Count of elements (updated) = 12 Stack elements...cloned 4000 3500 3000 2500 2000 1500 1250 1000 750 500 300 150 Count of elements in cloned stack(updated) = 12
Example
Let us now see another example −
using System; using System.Collections; public class Demo { public static void Main(){ Stack stack = new Stack(); stack.Push("Inspiron"); stack.Push("Alienware"); stack.Push("Projectors"); stack.Push("Monitors"); stack.Push("XPS"); stack.Push("Laptop"); stack.Push("Notebook"); Console.WriteLine("Stack elements..."); foreach(string val in stack){ Console.WriteLine(val); } Console.WriteLine("Count of elements = "+stack.Count); stack.Push("Headphone"); stack.Push("Keyboard"); stack.Push("Earphone"); Console.WriteLine("
Stack elements...updated"); foreach(string val in stack){ Console.WriteLine(val); } Console.WriteLine("Count of elements (updated) = "+stack.Count); Stack stack2 = (Stack)stack.Clone(); Console.WriteLine("
Stack elements...cloned"); foreach(string val in stack2){ Console.WriteLine(val); } Console.Write("Count of elements (updated) = "+stack2.Count); } }
Output
This will produce the following output −
Stack elements... Notebook Laptop XPS Monitors Projectors Alienware Inspiron Count of elements = 7 Stack elements...updated Earphone Keyboard Headphone Notebook Laptop XPS Monitors Projectors Alienware Inspiron Count of elements (updated) = 10 Stack elements...cloned Earphone Keyboard Headphone Notebook Laptop XPS Monitors Projectors Alienware Inspiron Count of elements (updated) = 10
