title: find and parse values from string
body: <p>I have a string that I am trying to parse the values from. It is in this format <code>"43,56,12,ddl=345"</code>.</p>
  
  <p>I am trying to store the ddl value (<code>345</code>) in a separate variable, then the other numbers in a list.</p>
  
  <pre><code>List&lt;int&gt; nums = new List&lt;int&gt;();
  int? ddlValue;
  </code></pre>
  
  <p>How do I go about this?</p>
