title: PetaPoco request for int[] type not working
body: <p>Hello I am trying to make a fetch to Microsoft SQL Server Management studio where in one of my columns there is an array of ints that I want to retrieve based on another column value.</p>
  
  <p>I am making the query like this:</p>
  
  <pre><code>int[] appsId = db.Fetch&lt;int[]&gt;($"SELECT Apps FROM [dbo].[Group] WHERE Name = @0", user.Groups[0]).FirstOrDefault();
  </code></pre>
  
  <p>The table has the following (shortened) info:</p>
  
  <pre><code>Name    Apps
  123     [356, 1589]
  </code></pre>
  
  <p>Using this I get the exception: 'Input string was not in a correct format'.</p>
  
  <p>Any ideas, thanks!</p>
