Bubble sort using C#

This short article is showing you how to write the simplest sort algorithm, Bubble sort, using C#.

Let I mentioned in my Quicksort article. The sorting method is built in to C# collection today. Somehow for learning we still need to know some of the sorting algorithm.

I steal the code from http://programcall.com/10/interview/write-a-sample-program-that-implements-bubble-sort-in-csnet.aspx and refactored it. It is running.

class myclass


    static void Main()


        int[] a = { 4, 6, 9, 83, 34, 45 };

        int[] b = BubbleSort(a);


        Console.WriteLine(“The Sorted array”);

        foreach (int aa in a)

            Console.Write(aa + ” “);





    private static int[] BubbleSort(int[] a)


        int temp;


        for (int pass = 1; pass <= a.Length – 2; pass++)


            for (int i = 0; i <= a.Length – 2; i++)


                if (a[i] > a[i + 1])


                    temp = a[i + 1];

                    a[i + 1] = a[i];

                    a[i] = temp;




        return a;
