Removing "" elements in a ArrayList
<p>I have this arraylist:</p>

<pre><code>ArrayList ftd = new ArrayList();
ftd.Add(new string[]{ "foo1.txt", "01.01.2011" });
ftd.Add(new string[]{ "foo2.txt", "04.01.2011" });
ftd.Add(new string[]{ "foo3.txt", "09.01.2011" });
</code></pre>

<p>and after some logic the arraylist looks something like this:</p>

<pre><code>[0] = { "foo1.txt", "01.01.2011" }
[1] = { "", "04.01.2011" }
[2] = { "foo3.txt", "09.01.2011" }
</code></pre>

<p>NOW: how do i loop thru ftd and remove elements there the elements first var is ""?</p>
