c# - How to put a (new line) inside a list box?

How to put the newline( ) in list box .selected item? Here I have code it generates the all links but I want to have all those link in listbox, these code is working but the links are not coming in the new line all comes in single line and my code is:

var links = TextBox1.Text.Split(new string[] { "
", "
" }, 
StringSplitOptions.RemoveEmptyEntries);

  foreach (var link in links)
        {
            if (!IsLinkWorking(link))
            {
                //Here you can show the error. You don't specify how you want to show it.
                TextBox2.ForeColor = System.Drawing.Color.Green; 
               TextBox2.Text += string.Format("{0}
Not working

 ", link);
                //ListBox1.SelectedItem+= string.Format("{0}
Not working

 ", link);
            }
            else
            {
               // ListBox1.SelectedValue += string.Format("{0}
Not working

 ", link);
                TextBox2.Text += string.Format("{0}
 working

", link);
            }

string[] values = TextBox2.Text.Split(',');

foreach (string value in values)
{
   if (value.Trim() == "")
       continue;
   ListBox1.Items.Add(value.Trim());    
       }
    }
}

You can use Regex.Split to split up your string to multiple lines like this:

foreach (string s in Regex.Split(TheStringwithNewLines, "
"))
ListBox.Items.Add(s);
