How to extract 2D Array from C# text box with multi line strings?

Question

I'm having trouble to extract a 2D array from the text. However, I'm able to get the 2D array if I read it from text files. Here's what I got when reading txt files and extract it to 2D array:

var array = File.ReadLines(path)
                    .Select(line => line.Split(" ".ToCharArray(), StringSplitOptions.RemoveEmptyEntries))
                    .ToArray();

Below are my codes when I tried to extract strings from textbox to 2d array, but I only able to get single dimension array. What is the equivalent of Select(line => line when using textbox?

var array = richTextBox1.Text.Split(" ".ToCharArray(), StringSplitOptions.RemoveEmptyEntries)
                    .ToArray();

How can I replicate the same results when extracting it from the text box?

Try this:

var array = richTextBox1.Text.Split('\n').Select(line => line.Split(" ".ToCharArray(), StringSplitOptions.RemoveEmptyEntries))
                .ToArray();

Basically, you want to split by line breaks to achieve the same effect as File.ReadLines.

Does the RichTextBox use \n or rather Environment.NewLine as separator?

@MarkusDeibel I'm not actually sure, if anybody knows feel free to edit

@mousetail tried your method and got an error saying 'cannot convert from 'string' to 'char'. and I changed "\n" to '\n' and now it works! Thank you so much!!
