How to order 2 different lists?
<p>I have a <code>Step</code> class and an <code>AutoStep</code> class</p>

<pre><code>class Step {
    int StepNumber;
}

class AutoStep {
    int StepNumber;
}
</code></pre>

<p>They are <strong>NOT</strong> inherited from any class and <strong>CANNOT</strong> inherit from any class.</p>

<p>I have to sort them by StepNumber and call specific method depending on their type(<code>Step</code> or <code>AutoStep</code>)</p>

<p>How can I do that?</p>
