JSON解析

static void Main(string[] args)
{
string serviceAddress = "http://20148414.dianpu.lianjia.com/shop/ershoufang/?p=1&type=1";
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(serviceAddress);
request.Method = "GET";
request.ContentType = "text/xml;charset=UTF-8";
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
Stream myResponseStream = response.GetResponseStream();
StreamReader myStreamReader = new StreamReader(myResponseStream, Encoding.UTF8);
string retString = myStreamReader.ReadToEnd();
myStreamReader.Close();
myResponseStream.Close();
string json = JsonHelper.JsonSerializer(retString);
Console.Write(json);
}
public static string JsonSerializer<T>(T t)
{

DataContractJsonSerializer ser = new DataContractJsonSerializer(typeof(T));

MemoryStream ms = new MemoryStream();

ser.WriteObject(ms, t);

string jsonString = Encoding.UTF8.GetString(ms.ToArray());

string jsonData = jsonString;

JavaScriptSerializer jsonSerialize = new JavaScriptSerializer();

jsonData = jsonSerialize.Deserialize<T>(jsonString).ToString();

ms.Close();

return jsonData;

}

不知道怎么办了！！！
想要提取JSON里的信息。

我非常喜欢的写法。就是用dynamic 类型。 

dynamic obj = jsonSerialize.Deserialize<dynamic>(jsonString);
//比如他有一个Name属性。
string name = obj.Name;//这样就ok了。不过如果没有这个属性。会报错，如果能肯定获取的数据没问题，就不加验证也可以。
我就喜欢这样写。很方便。你就当传过来的是一个对象这么用就行了。

关键是要提取JSON里的 "list":[{ "houseId":"105091421604","resblockId":"2411049771756", .... }，{ "houseId":"105091421604","resblockId":"2411049771756", .... }] 类似这种的数据。。。

可以得到 JSON 是：

jsonData = jsonSerialize.Deserialize<T>(jsonString).ToString(); 你反序列化之后又转成string是什么鬼？ 直接return jsonSerialize.Deserialize<T>(jsonString)出去不就行了吗？
