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 student names and then we sort them using the OrderByDescending() method using the below code.

var result = students.OrderByDescending(str => str);

Then we printed the filtered values on the console screen.
