Program:

The source code to demonstrate the use of the Linq OrderBuDescending() method, is given below. The given program is compiled and executed successfully on Microsoft Visual Studio.

//C# program to demonstrate the use of 
//Linq OrderByDescending() method.

using System;
using System.Linq;
using System.Collections.Generic;

class Demo
{
    static void Main(string[] args)
    {
        List<int> list = new List<int>() { 49, 34, 13, 56, 25, 65 };

        var result = list.OrderByDescending(num => num);

        Console.WriteLine("Sorted list in Descending order:");
        foreach (int value in result)
        {
            Console.Write(value + " ");
        }
        Console.WriteLine();
    }
}

Explanation:

In the above program, we created a Demo class that contains the Main() method to start the execution of the program. In the main() method we created the list of integers and then we sort them using the OrderByDescending() method using the below code.

Then we printed the filtered values on the console screen.
