title: Linq query between two list objects
body: <p>I have two objects:</p>
  
  <pre><code>ObjectA
  {
     string code;
     string country;
  }
  
  ObjectB
  {
     string code;
     string otherstuff;
  }
  </code></pre>
  
  <p>And I have <code>List&lt;objectA&gt;</code> and <code>List&lt;ObjectB&gt;</code> and I need to find all objects in <code>List&lt;ObjectB&gt;</code> which contains <code>objectA.Code</code>.
  But cannot manage to implement it on LINQ query.</p>
