已知一个xml文件，怎么进行反序列化到对象

已知一个xml文件，如何进行反序列化到对象
有个xml文件，其中有个结构是这样的
<Center>MSC
<SubCenter>CMC</SubCenter>
</Center>
请问如何设置对象，或者说如何进行反序列化
------解决方案--------------------

        public static string ObjectToXml(object obj, bool toBeIndented, Type type)

        {

            if (obj == null)

            {

                throw new ArgumentNullException("obj");

            }


            UTF8Encoding encoding = new UTF8Encoding(false);

            XmlSerializer serializer = new XmlSerializer(type);

            MemoryStream stream = new MemoryStream();

            XmlTextWriter writer = new XmlTextWriter(stream, encoding);

            writer.Formatting = (toBeIndented ? Formatting.Indented : Formatting.None);

            serializer.Serialize(writer, obj);

            string xml = encoding.GetString(stream.ToArray());

            writer.Close();

            return xml;

        }


        public static object XmlToObject(string xml, Type type)

        {

            if (xml == null)

            {

                throw new ArgumentNullException("xml");

            }

            object o = null;

            XmlSerializer serializer = new XmlSerializer(type);

            StringReader strReader = new StringReader(xml);

            XmlReader reader = new XmlTextReader(strReader);

            try

            {

                o = serializer.Deserialize(reader);

            }

            catch (InvalidOperationException e)

            {

                throw e;

            }

            catch (Exception e)

            {

                throw e;

            }

            finally

            {

                reader.Close();

            }

            return o;

        }

用XmlReader读这个文档，然后一个一个读Element来设置对象
