  • .net 解析嵌套JSON

    JSON格式文件如下:我们是要取出msgJsoncontent里面GeneralReportInfo下serviceData中的totalUseValue数据

        },
        "args": ""
    }

    第一步:

    responsecontent为上文的文件

    将JSON字符串JObject格式化:JObject job = JObject.Parse(responsecontent);

    第二步:将list里面的数据Jarray化: JArray array2 = JArray.Parse(job["result"]["list"].ToString());

    循环array2得到我们想要的数据,命名比较随意请见谅,以下是具体的解析代码:

                            for (int j = 0; j < array2.Count; j++)
                            {
                                dr = dt.NewRow();
                                JObject jObject = JObject.Parse(array2[j].ToString());
                                
                                string ss = jObject["msgJsoncontent"].ToString();
                                JObject js = JObject.Parse(ss);
                                
                                string sss = js["data"].ToString();
                                JArray array = JArray.Parse(sss);
                                //通过lamda表达式选择data里面serviceId=GeneralReportInfo再获取下面的totalUseValue值
                                foreach (var item in array.Where(a => a["serviceId"].ToString() == "GeneralReportInfo"))
                                {
                                    JObject a = JObject.Parse(item["serviceData"].ToString());
                                    string totalUseValue  = a["totalUseValue"].ToString();//此处我们就得到了我们想要的数据 
                                    
                                } 
                             }
