What is [....] in C#
<p>I encountered this in some .Net Framework code. I've never seen it before. Anyone know what it means?</p>

<pre><code>switch(msgFlags)
{
case Message.[....]:  // &lt;-- never seen this before?
    // do some stuff
}
</code></pre>

<p><strong>Edit:</strong> I was stepping through some of my code, when it threw an exception.  The exception broke on the lines somewhere in the Framework code. I can't remember now where at.  This was not a collapsed region.  The section is underlined in my editor with an 'Identifier Expected' error.  I'm wondering if it isn't some kind of placeholder for some super-secret secret squirrel code that Microsoft doesn't want anyone to see.</p>
