XML序列化与反序列化

    利用泛型实现XML的序列化与反序列化。

    1、序列化

        /// <summary>
        /// 将一个对象序列化为string
        /// </summary>
        /// <typeparam name="T">对象类型</typeparam>
        /// <param name="o">待序列化的对象</param>
        /// <returns>序列化后的字符串</returns>
        public static string ToXmlString<T>(T o)
        {
            XmlSerializer xs = new XmlSerializer(typeof(T));
            XmlSerializerNamespaces xmlns = new XmlSerializerNamespaces();
            xmlns.Add(String.Empty, String.Empty);
            string result = string.Empty;
            using (StringWriter sw = new StringWriter())
            {
                xs.Serialize(sw, o, xmlns);
                result = sw.ToString();
            }
            return result;
        }

    2、反序列化

        /// <summary>
        /// 将string反序列化为一个对象
        /// </summary>
        /// <typeparam name="T">对象类型</typeparam>
        /// <param name="xmlString">待反序列化的字符串</param>
        /// <returns>反序列化后的对象</returns>
        public static T FromXmlString<T>(string xmlString) where T : class
        {
            T result = default(T);
            if (string.IsNullOrWhiteSpace(xmlString))
            {
                return result;
            }
            XmlSerializer xs = new XmlSerializer(typeof(T));

            using (StringReader sr = new StringReader(xmlString))
            {
                result = xs.Deserialize(sr) as T;
            }
            return result;
        }
