HttpFileCollection always returns count > 0
<p>I have a form with 1 input type="file" element. I would expect that when no file is selected, in the code behind the collection of HttpFileCollection would be empty. </p>

<p>However it seems that the count is always greater than zero. </p>

<p>as demonstrated with the following code:</p>

<pre><code>Dim files As HttpFileCollection = Request.Files

        If files.Count &gt; 0 Then
           'At least one file has been uploaded
        End if
</code></pre>

<p>Am I experiencing a general quirk, or is this expected behavior?</p>

<p>Thanks in advance. </p>
