title: Check that value exists in a Generic List of Values
body: <p>I am trying to figure out how to check if testInt exists in all Car.SomeID in List</p>
  
  <p>So:</p>
  
  <pre><code>int testInt = 10;
  List&lt;Car&gt; myCars = GetCars();
  </code></pre>
  
  <p>I want to see if there is a match on 10 in any of myCards.SomeID</p>
