Very Simple if you have an Array
int[] arr = { 1, 2, 3, 5, 9, 0, 2, 10 };
arr.OrderBy(a => a);
arr.Reverse();
in case of list
List<int> abc = new List<int> { 1, 2, 3, 5, 9, 0, 2, 10 };
abc.Sort();
abc.Reverse();

Just use OrderByDescending of LINQ:
var list = new[] {20, 40, 60, 10, 30, 50};
var newList = list.OrderByDescending(x => x);
Console.WriteLine(string.Join(",", newList)); //60,50,40,30,20,10

You can try this
int[] array = new int[] { 20, 40, 60, 10, 30, 50 };
Array.Sort<int>(array,
new Comparison<int>((element1, element2) => element1.CompareTo(element2)));
to reverse sort
element2.CompareTo(element1)

@AmitMishra How is it working? the output is entirely different from what you have posted: "into the following order 60,40,50,20,30,10"

Sir can you provide me a answer using an example?

@AmitMishra can you provide exact rules for the sorting of the array?
