Sort an array in descending order

 

Sort an array in descending order

In this article we will see how to sort an array in descending order using various logics.

1. Using in build method | Using Array.Sort() and Array.Reverse() Method

public static void SortArray()         {                       int[] arr = new int[] { 1, 4, 2, 9, 5, 6,3,11 };               // Sort array in ascending order.             Array.Sort(arr);               // reverse array             Array.Reverse(arr);                      foreach (int value in arr)             {                 Console.Write(value + " ");             }           }

output

2. Sort an array in ascending order without using inbuilt C# function

public static void SortArray()         {                       int[] arr = new int[] { 1, 4, 2, 9, 5, 6,3,11 };               int temp = 0;               for (int i = 0; i <= arr.Length - 1; i++)             {                 for (int j = i + 1; j < arr.Length; j++)                 {                     if (arr[i] > arr[j])                     {                         temp = arr[i];                         arr[i] = arr[j];                         arr[j] = temp;                     }                 }             }             Console.WriteLine("Array sort in asscending order");             foreach (var item in arr)             {                 Console.WriteLine(item);             }             Console.ReadLine();           }

Output

3. Sort an array in descending order without using inbuilt C# function.
