C# program to sort names in ascending and descending order

I have a string of user names seperated by semi colon. I want a c# program that can sort these names in both ascending and descending order.


string strUserNames = "Rob;Mike;Able;Sara;Peter;John;Tom;Ben";

using System;

namespace SamplePrograms{    class SortNamesInAscendingAndDescendingOrder    {        public static void Main()        {            // Prompt the user to enter the list of user names            Console.WriteLine("Please enter list of names seperated by semi colon");                        // Read the user name list from the console            string strUserNames = Console.ReadLine();

            // Sampe list of user names that can be used as an input            // strUserNames = "Rob;Mike;Able;Sara;Peter;John;Tom;Ben";

            // Split the string into a string array based on semi colon            string[] arrUsersNames = strUserNames.Split(';');

            // Print the names before sorting using foreach loop            Console.WriteLine("Names before sorting");            foreach (string UserName in arrUsersNames)            {                Console.WriteLine(UserName);            }

            // Sort the elements in the array in ascending order            Array.Sort(arrUsersNames);

            // Print the elements of the array after sorting            Console.WriteLine("Names after sorting in ascending order");            foreach (string UserName in arrUsersNames)            {                Console.WriteLine(UserName);            }

            // Reverse the elements in the sorted array to get            // the elements in descending order            Array.Reverse(arrUsersNames);                        // Finally print the elements            Console.WriteLine("Names after sorting in descending order");            foreach (string UserName in arrUsersNames)            {                Console.WriteLine(UserName);            }

            Console.ReadLine();        }    }}
