1.序列化列表类型的xml字符串

        /// <summary>
        /// 解析XML   多次创建XmlSerializer对象，电脑内存会快速增大存在性能问题
        /// </summary>
        /// <typeparam name="T">类型</typeparam>
        /// <param name="strXML">xml内容</param>
        /// <param name="rootName">根目录</param>
        /// <returns></returns>
        public static List<T> XmlDESerializerText<T>(string strXML, string rootName) where T : class
        {
            try
            {
                using (StringReader sr = new StringReader(strXML))
                {
                    XmlSerializer serializer = new XmlSerializer(typeof(List<T>), new XmlRootAttribute(rootName));
                    return serializer.Deserialize(sr) as List<T>;
                }
            }
            catch (Exception ex)
            {
                return null;
            }
        }

        /// <returns></returns>
        public static T XmlDESerializer<T>(string strXML) where T : class
        {
            try
            {
                using (StringReader sr = new StringReader(strXML))
                {
                    XmlSerializer serializer = new XmlSerializer(typeof(List<T>));
                    return serializer.Deserialize(sr) as T;
                }
            }
            catch (Exception ex)
            {
                return null;
            }
        }
