The Program in C# Program to Sort Elements Of Array in Descending order is given below:

using System;

namespace ArraySortDescending
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("Hello Codeauri Family, enter the number of elements in the array to sort in descending order: ");
            int n = int.Parse(Console.ReadLine());
            int[] arr = new int[n];

            Console.WriteLine("Enter the elements of the array: ");
            for (int i = 0; i < n; i++)
            {
                arr[i] = int.Parse(Console.ReadLine());
            }

            Array.Sort(arr);
            Array.Reverse(arr);

            Console.WriteLine("Okay, the Sorted array in descending order: ");
            foreach (int item in arr)
            {
                Console.Write(item + " ");
            }
            Console.WriteLine();
        }
    }
}

Output:

Hello Codeauri Family, enter the number of elements in the array to sort in descending order:
3
Enter the elements of the array:
145
4
199
Okay, the Sorted array in descending order:
199 145 4

Pro-Tips💡

Here are the steps by steps execution of above program:

1. Displays a message asking the user to enter the number of elements in the array to be sorted.
2. Reads the number of elements in the array from the user.
3. Creates an array with the specified number of elements.
4. Displays a message asking the user to enter the elements of the array.
5. Reads the elements of the array from the user.
6. Sorts the array in ascending order using the Array.Sort method.
7. Reverses the order of the elements in the array using the Array.Reverse method.
8. Displays a message indicating that the array has been sorted in descending order.
9. Writes the sorted array elements to the console.
10. Exits the program.
