//加载xml及反序列化
            XmlDocument xdc = new XmlDocument();
            xdc.Load(url);
            XmlSerializer ser = new XmlSerializer(typeof(InModel));
            StringReader sr = new StringReader(xdc.InnerXml);
            InModeldocmodel = ser.Deserialize(sr) as InModel;   

//对象序列化xml         
　　　　　   OutModel outmodel = new OutModel();

            MemoryStream ms = new MemoryStream();
            serializer.Serialize(ms, outmodel );
            return Content(System.Text.Encoding.UTF8.GetString(ms.ToArray()), "text/xml");
