title: Check if List<Dynamic> is contain a object
body: <p>I have some object with different properties. And i want to store to List using <code>List&lt;dynamic&gt;</code> and i already did.</p>
  
  <p>But i have some problem when try to find specific object what I need.</p>
  
  <p>For example:</p>
  
  <p>I have 2 object <strong>Movie</strong> and <strong>Genre</strong></p>
  
  <p><strong>Movie Object</strong></p>
  
  <pre><code>Movie movie = new Movie()
      {
          Title = Title,
          Description = Description
      }; 
  </code></pre>
  
  <p><strong>Genre Object</strong></p>
  
  <pre><code>Genre genre = new Genre ()
      {
          Name = Name 
      }; 
  </code></pre>
  
  <p>And i store like this :</p>
  
  <pre><code>List&lt;dynamic&gt; dynamics = new List&lt;dynamic&gt;();
  dynamics.Add(movie);
  dynamics.Add(genre);
  </code></pre>
  
  <p><strong>I dont know to check the list is a movie or genre</strong></p>
  
  <p>I dont want use like <code>dynamics[0]</code> for get <code>Movie</code> object. because i have a lot more object than code below.</p>
  
  <p><strong>I try to use LINQ but did work or i miss something</strong></p>
