title: Oracle 11g odp.net driver issues with Null value
body: <p>I am having issues comparing null values with oracle 11g odp.net driver. It works fine with oracle 10g odp.net driver. If a column is null in the database, then in datarow it has a string value of <code>null</code>. </p>
  
  <p>This code fails:</p>
  
  <pre><code>int parentId =  row[PARENTID] != DBNull.Value ? int.Parse(row[PARENTID].ToString()) : 0;
  </code></pre>
  
  <p>Thanks</p>
