C# 根据url返回JObject

        public JObject GetHttpWebRequest(string url)
        {
            try
            {
                string result = "";
                HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url);

                req.Method = "POST";
                req.ContentType = "application/x-www-form-urlencoded";

                byte[] data = Encoding.UTF8.GetBytes(result);//把字符串转换为字节

                req.ContentLength = data.Length; //请求长度

                using (Stream reqStream = req.GetRequestStream()) //获取
                {
                    reqStream.Write(data, 0, data.Length);//向当前流中写入字节
                    reqStream.Close(); //关闭当前流
                }

                HttpWebResponse resp = (HttpWebResponse)req.GetResponse(); //响应结果

                Stream stream = resp.GetResponseStream();

                //获取响应内容
                using (StreamReader reader = new StreamReader(stream, Encoding.UTF8))
                {
                    result = reader.ReadToEnd();
                }

                JObject jo = (JObject)JsonConvert.DeserializeObject(result);//或者JObject jo = JObject.Parse(jsonText);

                return jo;
            }
            catch (Exception)
            {

                throw;
            }
        }

JObject jo = GetHttpWebRequest(url);
string zj1 = jo["data"].ToString();

JavaScriptSerializer Serializers = new JavaScriptSerializer();

//实例化类
ProcessingList pro = new ProcessingList();

//json字符串转为数组对象, 反序列化
objs = Serializers.Deserialize<List<Class>>(zj1);
