Serialize and Deserialize object to DB / XElement

    //To serialize into XElement:

        XmlSerializer x = new XmlSerializer(typeof(ComplexType));
        XDocument doc = new XDocument();
        ComplexType ct = _getComplexType();
        using (XmlWriter xw = doc.CreateWriter())
        {
            ComplexType ct = _getComplexType();
            x.Serialize(xw, complexType);
            xw.Close();
        }
        XElement el = doc.Root;

    //To deserialize into ComplexType:

        using (XmlReader xr = el.CreateReader())
        {
            ComplexType deserializedComplexType =
                x.Deserialize(xr) as ComplexType;
            xr.Close();
        }
