Why `args[0].Trim() == null` is always false?
<p>I have a method like this:</p>

<pre><code>public string StartCapture(string[] args)
{
    if(args[0].Trim() == null || args[0].Trim() == string.Empty )
    {
        //do stuff
    }
}
</code></pre>

<p>Why I get a note that <code>args[0].Trim() == null</code> will always be false?</p>
