title: Declare a class in inline-code in aspx/c#
body: <p>I've got a self contained <code>aspx</code> script that now needs a small class for one function. Is there any way to declare a class in the code of this page without adding a code behind (<code>aspx.cs</code>) file? </p>
  
  <p>I'd like to keep everything in one single file for neatness sake.</p>
