Display txt file contents in asp.net textbox or other

i was tring to write txt file data to a textbox, but it shows my data as one word without spaces. How do I write txt file content to a textbox and save its formatting? There is the code i tried:

 private void WriteData()
{
    if (File.Exists(Server.MapPath("App_Data/U3.txt")))
    {
        TextBox1.Text = File.ReadAllText(Server.MapPath("App_Data/U3.txt"));
    }
    File.WriteAllText(Server.MapPath("App_Data/U3.txt"), TextBox1.Text);
}

Edit: apparently it doesnt remove spaces, but new lines are gone and its all in one line Edit 2: alright now im trying to use ReadAllLines but how do i make this statement valid

TextBox1.Text = File.ReadAllLines(Server.MapPath("App_Data/U3.txt"));

First go to properties and change Textmode to Multi line and then try below code. It works.

protected void Page_Load(object sender, EventArgs e)
    {
        string file = "test.txt";
        string[] str = null;
        if (File.Exists(Server.MapPath(file)))
        {
            str = File.ReadAllLines(Server.MapPath(file));
        }
        foreach (string s in str)
        {
            TextBox1.Text = TextBox1.Text +"\n"  +s;
        }

    }

Maybe you can try to replace all newlines in the file output to <br/> tags, like this:

mystring.Replace(System.Environment.NewLine, "<br />");

ps. I found that answer here: text in the textbox doesnt retain its format
