Sample Solution:

C# Sharp Code:

using System; // Importing the System namespace for basic functionality
using System.Collections; // Importing collections for non-generic interfaces
using System.Collections.Generic; // Importing collections for generic interfaces
using System.Linq; // Importing LINQ for querying collections
using System.Text; // Importing classes for handling strings
using System.Threading.Tasks; // Importing classes for handling asynchronous tasks

namespace exercises // Defining a namespace called 'exercises'
{
    class Program // Defining a class named 'Program'
    {
        static void Main(string[] args) // The entry point of the program
        {               
            // Declaring and initializing an ArrayList 'item' using the 'test' method
            ArrayList item = test(new[] {"a", "aaa", "b", "bbb", "c", "ccc" }, 3);

            // Displaying a message to indicate the new array elements
            Console.Write("New array: ");

            // Iterating through each element in the 'item' ArrayList and displaying it
            foreach(var i in item)
            {
                Console.Write(i.ToString() + " ");
            }
        }                  

        // Method to filter strings of length 'n' from the input array and store them in an ArrayList
        static ArrayList test(string[] arr_str, int n)
        {
            ArrayList result_arra = new ArrayList(); // Initializing a new ArrayList

            // Looping through the input string array and adding strings of length 'n' to the ArrayList
            for (int i = 0; i < arr_str.Length; i++)
            {
                if (arr_str[i].Length == n) // Checking if the length of the string matches 'n'
                {
                    result_arra.Add(arr_str[i]); // Adding the string to the ArrayList
                }
            }
            return result_arra; // Returning the ArrayList containing strings of length 'n'
        }    
    } 
}

Sample Output:

New array: aaa bbb ccc
