C#json 解析

 

  Json样例一：

string jsonText=

{Code":0,"Message":"成功","Data":{"BoardProvinceName":"上海","BoardCityName":"上海","BoardDetailAddress":"普陀区怒江北路449弄8号C5","CourierName":"15601804660","CourierMobile":"15601804660","CargoNo":89,"BoardNo":3,"BoxNo":2,"DoorNo":3,"ExpressNo":"333333","CargoPassword":null,"Size":3,"Status":2,"StoreTime":"\/Date(1406772770183)\/","ExtractionTime":"\/Date(1415185496877)\/","CustomerMobile":"15601804660","CourierPId":"321323198902082117"}}}

 

JObject jo = JObject.Parse(jsonText);
string strCode= jo["Code"].ToString();//Code:0

string ddaf = GetJsonValue(jo.Children(), "BoardDetailAddress");//BoardDetailAddress:普陀区怒江北路449弄8号C5

       string a = j["name"].ToString();

      string b = j["data"].ToString();
    }

  

   多层嵌套

string jsonData1 = "{\"addr\":[{\"city\":\"guangzhou\",\"province\":\"guangdong\"},{\"city\":\"guiyang\",\"province\":\"guizhou\"}]}";
            JObject jsonObj1 = JObject.Parse(jsonData1);
            JArray jar1 = JArray.Parse(jsonObj1["addr"].ToString());
            JObject j0 = JObject.Parse(jar1[0].ToString());
            JObject j1 = JObject.Parse(jar1[1].ToString());
            string city1 = j0["city"].ToString();   //guangzhou
            string city2 = j0["city"].ToString();   //guiyang
