Delete null items from a dictionary
<p>I have a web page which queries a database and and stores the results in a mapped array dictionary type. the issue im having is that some of the "rows" in the results are null, so I might have 20 records returned and the first three might be null</p>

<p>so I am going through each individual array and checking if that is null, so my questions is how do I delete this from the collection of array.</p>

<p>if I do something like </p>

<pre><code>Objects[i].Remove(Objects[i].Keys.ToString());
</code></pre>

<p>I get an error because Objects[i] is null</p>
