How to check for read permissions on a folder?
<p>I know that this method is good to check if a user has write permissions to folder:</p>

<pre><code>Directory.GetAccessControl(path);
</code></pre>

<p>If it throws <code>UnauthorizedAccessException</code> I know that the user has read permission or non permission.</p>

<p>How to know if a user has read permissions?</p>

<p>Is <code>Directory.Exists(path)</code> a good enough solution?</p>
