.Trim() when string is empty or null
<p>I'm receiving some data from the client in the form of json.
I'm writing this:</p>

<pre><code>string TheText; // or whould it be better string TheText = ""; ?
TheText = ((serializer.ConvertToType&lt;string&gt;(dictionary["TheText"])).Trim());
</code></pre>

<p>If the variable that's being parsed from json comes back empty, does this code crash when I call the .Trim() method?</p>

<p>Thanks.</p>
