Oracle 11g odp.net driver issues with Null value

Question

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 null.

This code fails:

int parentId =  row[PARENTID] != DBNull.Value ? int.Parse(row[PARENTID].ToString()) : 0;

Thanks

Here :

var para6 = new OracleParameter("pOrganizationParentId", OracleDbType.Long){
    IsNullable = true,
};

if (string.IsNullOrEmpty(organizationParentId)) {
    para6.Value = null; 
} else {
    para6.Value = long.Parse(organizationParentId);
}
