Get or set the element at the specified index in ArrayList in C#

To get or set the element at the specified index in ArrayList, the code is as follows −

Example

 Live Demo

using System;
using System.Collections;
public class Demo {
   public static void Main() {
      ArrayList arrList = new ArrayList();
      arrList.Add("Laptop");
      arrList.Add("Desktop");
      arrList.Add("Notebook");
      arrList.Add("Ultrabook");
      arrList.Add("Tablet");
      arrList.Add("Headphone");
      arrList.Add("Speaker");
      Console.WriteLine("Elements in ArrayList...");
      foreach(string str in arrList) {
         Console.WriteLine(str);
      }
      Console.WriteLine("Element at index 5 = " + arrList[5]);
   }
}

Output

This will produce the following output −

Elements in ArrayList...
Laptop
Desktop
Notebook
Ultrabook
Tablet
Headphone
Speaker
Element at index 5 = Headphone

Example

Let us see another example −

 Live Demo

using System;
using System.Collections;
public class Demo {
   public static void Main() {
      ArrayList arrList = new ArrayList();
      arrList.Add("Laptop");
      arrList.Add("Desktop");
      arrList.Add("Notebook");
      arrList.Add("Ultrabook");
      arrList.Add("Tablet");
      arrList.Add("Headphone");
      arrList.Add("Speaker");
      Console.WriteLine("Elements in ArrayList...");
      foreach(string str in arrList) {
         Console.WriteLine(str);
      }
      Console.WriteLine("Element at index 5 = " + arrList[5]);
      arrList[5] = "SSD";
      Console.WriteLine("Element at index 5 (Updated) = " + arrList[5]);
   }
}

Output

This will produce the following output −

Elements in ArrayList...
Laptop
Desktop
Notebook
Ultrabook
Tablet
Headphone
Speaker
Element at index 5 = Headphone
Element at index 5 (Updated) = SSD
