Question

I have a listbox being populated from textbox entry.

{
        textBox2.Text.Replace("\r\n", "\r");
        listBox1.Items.Add(textBox2.Text);
    }

Whats happening is the textbox is being populated in a single column format, when it moves over to the listbox the \r\n gets changed to the black squares and does populate the same as it looked in the textbox.

Answer 1

You might want to do a string Split instead.

string[] items = Regex.Split(textBox2.Text, "\r\n");
listBox1.Items.AddRange(items);
