StructLayout only for struct?
<p>I noticed that there are many places we have something like this:</p>

<pre><code>[StructLayout(LayoutKind.Sequential, Pack = 1)]
    public class E2H_LANEFIND_DATA_T
    {
....
}
</code></pre>

<p>class definition with <code>StructLayout</code>. Is that ok or <code>StructLayout</code> is only for <code>struct</code>?</p>
