File.Open just hangs and does nothing
<p>I've never came across this issue. Can anybody tell me why does this code just hang and hang forever:</p>

<pre><code> FileStream stream = File.Open("abc.xls", FileMode.Open, FileAccess.Read);
</code></pre>

<p>I am using Visual Studio 2010 Premium edition, Windows 7.</p>

<p>What can be the possible causes? Either it should throw exception or just run fine. Why does the program just hang and never reach the next line of code after this?</p>

<p>Thanks in advance :)</p>
