object reference is required for the non-static field
<p>What am I doing wrong here?</p>

<pre><code>return listBoxKeywords.Items[rnd.Next(0, listBoxKeywords.Items.Count)].ToString();
</code></pre>

<p>I get the following error:</p>

<p>Error   1   An object reference is required for the non-static field, method, or property </p>
