XML Serialization and Deserialization using generics

I love generics, and I when I come across a requirement where I had  to serialize a variety of objects to xml and deserialize back to the object, generics was the way to go, and resulted in following methods.

        // De-Serializes the request into type object

        public static XmlDocument SerializeToXml(T objectToSerialize)

        {

            XmlDocument serializedXml = new XmlDocument();

            XmlSerializer xmlSerializer = new XmlSerializer(typeof(T));

            using (MemoryStream momoryStream = new MemoryStream())

            {

                XmlTextWriter xmlTextWriter = new XmlTextWriter(momoryStream, null);

                xmlSerializer.Serialize(xmlTextWriter, objectToSerialize);

                // Rewind the Stream.

                momoryStream.Seek(0, SeekOrigin.Begin);

                // load from stream;

                serializedXml.Load(momoryStream);

            }

            return serializedXml;

        }

        // De-Serializes the request into class object

        public static T DeserializeXml(XmlNode xmlToDesearialized)

        {

            if (xmlToDesearialized == null) throw new ArgumentNullException("xmlToDesearialized");

            T deserializedObject = default(T);

            XmlSerializer xmlSerializer = new XmlSerializer(typeof(T));

            using (StringReader stringReader = new StringReader(xmlToDesearialized.OuterXml))

            {

                XmlTextReader xmlTextReader = new XmlTextReader(stringReader);

                deserializedObject = (T)xmlSerializer.Deserialize(xmlTextReader);

            }

            return deserializedObject;

        }
