What is the ArrayList class in C#?

ArrayList class represents an ordered collection of an object that can be indexed individually. It is basically an alternative to an array.

The following are the methods of Arraylist class −

Let us see an example of ArrayList −

To sort an ArrayList in C#, use the Sort() method.

The following is the ArrayList −

ArrayList arr = new ArrayList();
arr.Add(32);
arr.Add(12);
arr.Add(55);
arr.Add(8);
arr.Add(13);

Now the Sort() method is used to sort the ArrayList −

arr.Sort();

You can try to run the following code to sort an ArrayList in C# −

Example

 Live Demo

using System;
using System.Collections;

namespace Demo {
   class Program {

      static void Main(string[] args) {

         ArrayList arr = new ArrayList();

         arr.Add(89);
         arr.Add(34);
         arr.Add(77);
         arr.Add(90);

         Console.Write("List: ");
         foreach (int i in arr) {
            Console.Write(i + " ");
         }

         Console.WriteLine();
         Console.Write("Sorted List: ");
         arr.Sort();
         foreach (int i in arr) {
            Console.Write(i + " ");
         }
         Console.WriteLine();
         Console.ReadKey();
      }
   }
}

Output

List: 89 34 77 90
Sorted List: 34 77 89 90
