Step 2: Backend Logic – SortArray.aspx.cs

using System;
using System.Linq;

public partial class SortArray : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
    }

    protected void btnSort_Click(object sender, EventArgs e)
    {
        string input = txtNumbers.Text.Trim();

        if (string.IsNullOrEmpty(input))
        {
            lblResult.Text = "Please enter numbers separated by commas.";
            lblResult.ForeColor = System.Drawing.Color.Red;
            return;
        }

        try
        {
            // Convert comma-separated string to integer array
            int[] numbers = input.Split(',').Select(n => Convert.ToInt32(n.Trim())).ToArray();

            // Manual Sorting (Bubble Sort logic)
            for (int i = 0; i < numbers.Length - 1; i++)
            {
                for (int j = i + 1; j < numbers.Length; j++)
                {
                    if (numbers[i] > numbers[j])
                    {
                        // Swap values
                        int temp = numbers[i];
                        numbers[i] = numbers[j];
                        numbers[j] = temp;
                    }
                }
            }

            lblResult.Text = $"Sorted Array: {string.Join(", ", numbers)}";
            lblResult.ForeColor = System.Drawing.Color.Green;
        }
        catch
        {
            lblResult.Text = "Invalid input! Please enter only numbers separated by commas.";
            lblResult.ForeColor = System.Drawing.Color.Red;
        }
    }
}

Real-Time Example Flow

Open SortArray.aspx in your browser.
Enter numbers like:
5, 3, 8, 1, 2
Click “Sort Array”.
Output will be:
```
Sorted Array: 1, 2, 3, 5, 8
```

Explanation

Step	Description
1	User enters numbers separated by commas.
2	Numbers are split and converted into an integer array.
3	The code uses nested loops (Bubble Sort) to compare and swap elements.
4	Sorted array is displayed in ascending order.

Example Input / Output Table

Input	Output
10, 5, 2, 8, 1	1, 2, 5, 8, 10
9, 4, 7, 2	2, 4, 7, 9
100, 25, 50, 75	25, 50, 75, 100
3, 3, 2, 1	1, 2, 3, 3
