title: How to assign contents of List<String> to a RichTextBox?
body: <p>I've tried this:</p>
  
  <pre><code>richTextBoxResults.Text = listStrSessionIdLines.ToString();
  </code></pre>
  
  <p>...but get the List's ToString() representation (I guess that's what it is: "System.Collections.Generic.List`1[System.String]").</p>
  
  <p>...and I've tried to try this:</p>
  
  <pre><code>listStrSessionIdLines.CopyTo(richTextBoxResults.Lines);
  </code></pre>
  
  <p>...but I get, "<em>Argument Exception was unhandled. Destination array was not long enough. Check destIndex and length, and the array's lower bounds.</em>"</p>
  
  <p>Does this mean I have to assign the RichTextBox a number of lines first, or...???</p>
