title: Cast dynamic dapper query
body: <p>Im trying to convert a dynamic query from dapper to IDictionary</p>
  
  <pre><code>        const string sql = @"SELECT Name, Street FROM Contact";
          dynamic query = null;
  
          using (var cn = Connection)
          {
              query = cn.Query&lt;dynamic&gt;(sql);
          }
  
          var rows = query as IDictionary&lt;string, object&gt;;
  
          foreach (var row in rows)
          {
              // Getting values and objects
          }
  </code></pre>
  
  <p>But the cast always return null. Any clue?</p>
