get all characters to right of last dash
<p>I have the following:</p>

<pre><code>string test = "9586-202-10072"
</code></pre>

<p>How would I get all characters to the right of the final <code>-</code> so 10072. The number of characters is always different to the right of the last dash.</p>

<p>How can this be done?</p>
