xml对象的序列化和反序列化

 对象序列化：

/// <summary>
        /// 将一个对象序列化为XML字符串
        /// </summary>
        /// <param name="o">要序列化的对象</param>
        /// <param name="encoding">编码方式</param>
        /// <returns>序列化产生的XML字符串</returns>
        public static string XmlSerialize(object o, Encoding encoding)
        {
            using (MemoryStream stream = new MemoryStream())
            {
                XmlSerializeInternal(stream, o, encoding);

                stream.Position = 0;
                using (StreamReader reader = new StreamReader(stream, encoding))
                {
                    return reader.ReadToEnd();
                }
            }
        }

        private static void XmlSerializeInternal(Stream stream, object o, Encoding encoding)
        {
            if (o == null)
                throw new ArgumentNullException("o");
            if (encoding == null)
                throw new ArgumentNullException("encoding");

            XmlSerializer serializer = new XmlSerializer(o.GetType(), string.Empty);

            XmlWriterSettings settings = new XmlWriterSettings();
            settings.Indent = false;
            //settings.NewLineChars = " ";
            settings.Encoding = encoding;
            settings.IndentChars = "    ";

            using (XmlWriter writer = XmlWriter.Create(stream, settings))
            {
                var ns = new XmlSerializerNamespaces();
                ns.Add(string.Empty, string.Empty);
                serializer.Serialize(writer, o, ns);
                writer.Close();
            }
        }

对象反序列化：

 /// <summary>
        /// 从XML字符串中反序列化对象
        /// </summary>
        /// <typeparam name="T">结果对象类型</typeparam>
        /// <param name="s">包含对象的XML字符串</param>
        /// <param name="encoding">编码方式</param>
        /// <returns>反序列化得到的对象</returns>
        public static T XmlDeserialize<T>(string s, Encoding encoding) where T : class
        {
            try
            {
                if (string.IsNullOrEmpty(s))
                    throw new ArgumentNullException("s");
                if (encoding == null)
                    throw new ArgumentNullException("encoding");

                XmlSerializer mySerializer = new XmlSerializer(typeof(T));
                using (MemoryStream ms = new MemoryStream(encoding.GetBytes(s)))
                {
                    using (StreamReader sr = new StreamReader(ms, encoding))
                    {
                        var temp = mySerializer.Deserialize(sr);
                        return (T)temp;
                    }
                }
            }
            catch (Exception ex)
            {               
                return null;
            }

        }
