title: String[]-Array in ListBox
body: <p>I'm rather new to programing and especially to c#.
  I want to import a Txt-File to a listBox.
  I using following code, but all I get to see in the listBox are several lines with "String[]-Array" and not the real line from the Text-File.</p>
  
  <pre><code>private void button2_Click(object sender, EventArgs e)
  {
      OpenFileDialog op = new OpenFileDialog();
      if (op.ShowDialog() == DialogResult.OK)
      {
          textBox2.Text = op.FileName;
      }
  
      List&lt;string[]&gt; lines = File.ReadLines(textBox2.Text)
                             .Select(r =&gt; r.TrimEnd('#'))
                             .Select(line =&gt; line.Split(','))
                             .ToList();
      listBox1.DataSource = lines;
  
  }
  </code></pre>
  
  <p>Can you help me out and maybe give me a small hint what a did wrong?</p>
  
  <p>Thanks for your help</p>
