ASP.NET MVC -反序列化来自SOAP web服务的响应

这是我在MVC中的代码:

    string url = "https://api....";
    HttpWebRequest httpWebRequest = (HttpWebRequest)WebRequest.Create(url);
    httpWebRequest.Method = "POST";
    httpWebRequest.ContentType = "application/x-www-form-urlencoded";
    string postData = "<?xml version='"1.0'"?>" +
                        "<request>" +
                            "<login>" + Login + "</login>" +
                            "<password>" + Password + "</password>" +
                            "<limit>" +
                                "<offset>10</offset>" +
                                "<limit>10</limit>" +
                            "</limit>" +
                        "</request>";
    try
    {
        using (StreamWriter requestWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
        {
            requestWriter.Write(postData);
        }
    }
    catch (System.Net.WebException ex)
    {
        return null;
    }
    HttpWebResponse httpWebResponse = (HttpWebResponse)httpWebRequest.GetResponse();
    Stream responseStream = httpWebResponse.GetResponseStream();
    StreamReader streamReader = new StreamReader(responseStream);
    var serializer = new System.Xml.Serialization.XmlSerializer(typeof(Class.hotels));
    Class.hotels hotel = (Class.hotels)serializer.Deserialize(streamReader);
    streamReader.Close();
    responseStream.Close();
    httpWebResponse.Close();

我在我的Windows Phone 7项目中得到了相同的功能(异步调用的小变化)，它正在工作。我已经从WP7项目添加到MVC类，我现在正在尝试MVC。一切都在工作，但在最后我得到了0项酒店(但在WP我有项目在那里)。我试着把streamReader读到字符串，我得到了正确的答案，所以问题一定是反序列化。

那么有什么问题呢?如果类是错误的，我从XmlSerializer得到错误消息，我是对的吗(在WP中它也不会工作)?但我不知道还有什么问题。谢谢你的帮助
