TextBox is not creating newline when reading text file C#-CodePudding

I have this program that supposed to reads multiple text files on the same folder, in that folder there's 2 text files which are supposed to be read, ok now I have to generate a new TextBox based on the total numbers of text files in that folder.

Main Goal

Load the contents of those files in each textbox

File1.txt contents will be loaded into TextBox1.
File2.txt contents will be loaded into TextBox2.

Content of File1.txt:

Title 1
ABCDEFG

Content of File2.txt:

Title 2
1234567890

The problem

Loading the contents of those files into each TextBoxes works fine, but the problem is that the newline isn't created on the TextBoxes.

Instead I got this on each textboxes:

TextBox 1:

Title 1ABCDEFG

TextBox 2:

Title 21234567890

Do the necessary stuff as soon the program loads:

    private void Form1_Load(object sender, EventArgs e) {

        flowLayoutPanel1.AutoScroll = true;

        var dirs_notes = @"C:\MAIN_LOC\DATA_LOC\";
        var count_notes = Directory.GetFiles(dirs_notes,"*.*",SearchOption.AllDirectories).Count();

        string setup_path = @"C:\MAIN_LOC\DATA_LOC\";
        if(Directory.Exists(setup_path)) {
            string[] get_notes = Directory.GetFiles(dirs_notes, "*.txt", SearchOption.AllDirectories);
            string[] get_texts = get_notes.Select(x => File.ReadAllText(x)).ToArray();

            for(int i=0; i<count_notes; i  ) {
                int top = 25;
                int h_p = 170;
                var load_note = new Guna2TextBox() {
                    Text = "\n"   get_texts[i],
                    Name = "Note"   i,
                    Multiline = true,
                    AcceptsTab = true,
                    AcceptsReturn = true,
                    WordWrap = false,
                    Width = 230,
                    Height = 145,
                    BorderRadius = 8,
                    Font = new Font("Bahnschrift", 13),
                    ForeColor = Color.White,
                    FillColor = ColorTranslator.FromHtml("#1E1E1E"),
                    BorderColor = ColorTranslator.FromHtml("#2C2C2C"),
                    Location = new Point(450, top)
                };
                top  = h_p;
                flowLayoutPanel1.Controls.Add(load_note);
                }
            } else {
                MessageBox.Show("There's problem with loading notes..", "Flow Notes System");
            }
    }

CodePudding user response：

A fix could be using the Lines property instead of the Text property.

var dirs_notes = @"C:\MAIN_LOC\DATA_LOC\";

// Be sure to count only txt files here...
var count_notes =  Directory.GetFiles(dirs_notes,"*.txt",SearchOption.AllDirectories).Count();

string setup_path = @"C:\MAIN_LOC\DATA_LOC\";
if(Directory.Exists(setup_path)) {
    string[] get_notes = Directory.GetFiles(dirs_notes, "*.txt", SearchOption.AllDirectories);
    var get_texts = get_notes.Select(x => File.ReadLines(x));

    for(int i=0; i<count_notes; i  ) {
        ....
        var load_note = new Guna2TextBox() {
        Lines = "\n"   get_texts[i].ToArray(),

But a better approach is to use this instead:

// No counting here (counting means load all 
// files names in a memory array and the get its length
var files = Directory.EnumerateFiles(dirs_notes,"*.txt",SearchOption.AllDirectories)


int i = 1;
// Enumerate files one by one without loading all names in memory
foreach(string file in files) {
   int top = 25;
   int h_p = 170;
   var load_note = new Guna2TextBox() {
       // Set the textbox with the current file lines content
       // again one by one without loading all texts in memory
       Lines = File.ReadLines(file).ToArray(),
       Name = "Note"   i,
       ...
   }
   i  ;
   .....
}
