Sort an array in descending order using C#

Declare an array and initialize −

int[] arr = new int[] {    87,    23,    65,    29,    67 };

To sort, use the Sort() method and CompareTo() to compare and display in decreasing order −

Array.Sort < int > (arr, new Comparison < int > ((val1, val2) => val2.CompareTo(val1)));

Let us see the complete code −

Example

 Live Demo

using System; using System.Collections.Generic; using System.Text; public class Demo {    public static void Main(string[] args) {       int[] arr = new int[] {          87,          23,          65,          29,          67       };       // Initial Array       Console.WriteLine("Initial Array...");       foreach(int items in arr) {          Console.WriteLine(items);       }       Array.Sort < int > (arr, new Comparison < int > ((val1, val2) => val2.CompareTo(val1)));       // Sorted Array       Console.WriteLine("Sorted Array in decreasing order...");       foreach(int items in arr) {          Console.WriteLine(items);       }    } }

Output

Initial Array... 87 23 65 29 67 Sorted Array in decreasing order... 87 67 65 29 23
