Sort method can be used to perform sorting in arraylist's element in an ascending order. Now In order to print or see the elements in descending order we can reverse the sorted element in the arraylist using the reverse method.

Example

namespace ConsoleApplication1

{

    class Program

    {

        static void Main(string[] args)

        {

            ArrayList numbers = new ArrayList();

            numbers.Add(10);

            numbers.Add(22);

            numbers.Add(3);

            numbers.Add(5);

            numbers.Add(9);

            Console.WriteLine("The elements of the arraylist are:");

            foreach (int i in numbers)

            {

                Console.WriteLine(i);

            }

            numbers.Sort();

            Console.WriteLine("After sorting the elements of the arraylist are:");

            foreach (int i in numbers)

            {

                Console.WriteLine(i);

            }

            numbers.Reverse();

            Console.WriteLine("After apply the reverse method the number of element in the arraylist are:");

            foreach (int i in numbers)

            {

                Console.WriteLine(i);

            }

        }

    }

}
