How to sort an array of numbers in C#

c sharp1min read

In this example, you will learn about how to sort an array of numbers both ascending and descending order in C# by using a built-in sort() method.

Sorting array of numbers in ascending order

By default, the sort() method sorts the array in ascending order.

using System;

public class SortProgram
{
    public static void Main()
    {
        // intializing new array
        int[] myArr= new int[5] {1,5,3,8,21};

         // sorting array in ascending order
        Array.Sort(myArr);

        foreach (int val in myArr)
            { // printing the each sorted value
              Console.WriteLine(val);
            }
    }
}

Output:

Sorting array of numbers in descending order

For descending order, we need to use the Array.Reverse() method.

using System;

public class SortProgram
{
    public static void Main()
    {
        // intializing new array
        int[] myArr= new int[5] {1,5,3,8,21};


        Array.Sort(myArr);
        Array.Reverse(myArr); // sorting in descending order

        foreach (int val in myArr)
            { // printing the each sorted value
              Console.WriteLine(val);
            }
    }
}
