从wcf Web服务读取xml返回

Question

我有一个课程

public class SelectedRoomAvailability
    {
        public DataTable CardType { get; set; }
        public DataTable CountryList { get; set; }
    }

以及以xml格式返回输出的方法

public List<SelectedRoomAvailability> RoomAvailability(params...)
{
}

下面是我得到的输出

 <RoomAvailabilityResponse xmlns="http://webservice.hotel.com.au/">


     <RoomAvailabilityResult xmlns:a="http://schemas.datacontract.org/2004/07/HotelWcfService" xmlns:i="http://www.w3.org/2001/XMLSchema-instance">

我使用以下代码来阅读此xml

var request = WebRequest.Create(webserviceurl);
        request.Method = "GET";
        request.ContentType = "application/XML";
        String responseFromServer = "No response from server";
        using (var response = (HttpWebResponse)request.GetResponse())
        {
            using (var dataStream = response.GetResponseStream())
            {
                if (dataStream != null)
                {
                    using (var reader = new StreamReader(dataStream))
                    {
                        responseFromServer = reader.ReadToEnd();
                    }
                }
            }
        }

XmlDocument doc = new XmlDocument();
        doc.LoadXml(responseFromServer);            


XmlNodeList xnl = doc.GetElementsByTagName("a:CardType");


DataSet dt = new DataSet();
            dt.ReadXmlSchema("<?xml version=\"1.0\" encoding=\"utf-8\"?><NewDataSet>" + xnl.Item(0).InnerXml + "</NewDataSet>");
            dt.ReadXml("<?xml version=\"1.0\" encoding=\"utf-8\"?><NewDataSet>" + xnl.Item(0).InnerXml + "</NewDataSet>", XmlReadMode.IgnoreSchema);

我google了很多，发现上面的代码，但它不起作用。我从最近2天开始面对这个问题，最后我来找你们，请帮助我。

我想从输出中绑定数据集，以便根据我的要求使用该数据集。

我在博客中看到输出来自序列化，我试图反序列化，但即使在那里我也失败了。它也不允许我这样做。

请大家帮我读一下这个xml并将其存储到数据集或数据表或字典中，c＃对象支持的任何内容。

提前完成了......
