How to create a shallow copy of ArrayList in C#?

To create a shallow copy of ArrayList in C#, the code is as follows −

Example

 Live Demo

using System; using System.Collections; public class Demo {    public static void Main(){       ArrayList list = new ArrayList();       list.Add("One");       list.Add("Two");       list.Add("Three");       list.Add("Four");       list.Add("Five");       list.Add("Six");       list.Add("Seven");       list.Add("Eight");       Console.WriteLine("ArrayList elements...");       foreach(string str in list){          Console.WriteLine(str);       }       Console.WriteLine("ArrayList is read-only? = "+list.IsReadOnly);       Console.WriteLine("Does the element Six in the ArrayList? = "+list.Contains("Six"));       list.Insert(4, "Twelve");       Console.WriteLine("
ArrayList elements...UPDATED");       foreach(string str in list){          Console.WriteLine(str);       }       ArrayList list2 = new ArrayList();       list2 = (ArrayList)list.Clone();       Console.WriteLine("
Cloned ArrayList...");       foreach(string str in list2){          Console.WriteLine(str);       }    } }

Output

This will produce the following output −

ArrayList elements... One Two Three Four Five Six Seven Eight ArrayList is read-only? = False Does the element Six in the ArrayList? = True ArrayList elements...UPDATED One Two Three Four Twelve Five Six Seven Eight Cloned ArrayList... One Two Three Four Twelve Five Six Seven Eight

Example

Let us now see another example −

 Live Demo

using System; using System.Collections; public class Demo {    public static void Main(String[] args){       ArrayList list1 = new ArrayList();       list1.Add("A");       list1.Add("B");       list1.Add("C");       list1.Add("D");       list1.Add("E");       list1.Add("F");       list1.Add("G");       list1.Add("H");       list1.Add("I");       Console.WriteLine("Elements in ArrayList1...");       foreach (string res in list1){          Console.WriteLine(res);       }       ArrayList list2 = new ArrayList();       list2.Add("A");       list2.Add("B");       list2.Add("C");       list2.Add("D");       list2.Add("E");       list2.Add("F");       list2.Add("G");       list2.Add("H");       list2.Add("I");       list2.Add("G");       list2.Add("I");       Console.WriteLine("Elements in ArrayList2...");       foreach (string res in list2){          Console.WriteLine(res);       }       Console.WriteLine("Count of elements in ArrayList2 = " + list2.Count);       list2.Remove("G");       Console.WriteLine("Elements in ArrayList2... (UPDATED)");       foreach (string res in list2){          Console.WriteLine(res);       }       Console.WriteLine("Count of elements in ArrayList2 (Updated) = " + list2.Count);       ArrayList list3 = new ArrayList();       list3 = (ArrayList)list2.Clone();       Console.WriteLine("
Cloned ArrayList from ArrayList2...");       foreach(string str in list3){          Console.WriteLine(str);       }    } }

Output

This will produce the following output −

Elements in ArrayList1... A B C D E F G H I Elements in ArrayList2... A B C D E F G H I G I Count of elements in ArrayList2 = 11 Elements in ArrayList2... (UPDATED) A B C D E F H I G I Count of elements in ArrayList2 (Updated) = 10 Cloned ArrayList from ArrayList2... A B C D E F H I G I
