ArrayList in C#

CsharpServer Side ProgrammingProgramming

A resizable implementation of the List interface is called ArrayList. It is a non-generic type of collection in C# that dynamically resizes.

Let us see how to initialize ArrayList in C# −

ArrayList arr= new ArrayList();

Add an element like the below-given code snippet −

ArrayList arr1 = new ArrayList();
arr1.Add(120);
arr1.Add(160);

Let us see the complete example to implement ArrayList in C# −

Example

Live Demo

using System;
using System.Collections;

public class MyClass {
   public static void Main() {
      ArrayList arr1 = new ArrayList();
      arr1.Add(120);
      arr1.Add(160);

      ArrayList arr2 = new ArrayList();
      arr2.Add(200);
      arr2.Add(240);

      arr1.AddRange(arr2);

      for (int i = 0; i < arr1.Count; i++)
      Console.WriteLine(arr1[i]);
   }
}

Output

120
160
200
240
