Sorting Numbers in a Textbox: A Guide to Ascending Order in VB.NET

Have you ever faced the challenge of sorting numbers contained within a multiline textbox? If you’re using VB.NET and need to put these numbers in ascending order, you’re in the right place! In this guide, we will explore a common problem involving textbox number lines and provide a clear solution to help you achieve the desired output. Let's dive in!

The Challenge

Imagine you have a multiline textbox filled with numbers like this:

Your goal is to rearrange these numbers in ascending order while preserving the structure of each line. The desired output should look like this:

However, you might be using code that doesn't handle the commas correctly, leading to results such as 27414454, which is not what you want!

How to Sort Lines of Numbers

To solve this problem, you need to process each line individually. Here's how you can achieve that using VB.NET in a structured way:

Step 1: Split Each Line

The first step is to split each line based on the comma delimiter. This will convert each line of text into an array of numbers that can be sorted.

Step 2: Sort the Arrays

Once you have the numbers in an array format, you can sort them in ascending order using a simple sorting mechanism.

Step 3: Join the Numbers Back Together

After sorting, you’ll need to join the numbers back into a string format, ready to display in your output textbox.

Implementation Code

Here’s a concise implementation in VB.NET that encapsulates the above steps:

Breakdown of the Code

txtInput.Lines: This refers to the original textbox containing the lines of numbers.

Split: This method splits each line into individual number strings, using the comma as a delimiter.

OrderBy: Sorts the number strings in ascending order.

String.Join: Reassembles the sorted numbers back into a single string, joined by commas.

ToArray: Converts the final result back into an array of strings, which can be assigned back to the output textbox.

Example

If your txtInput contains the lines:
