假如我们得到了一个json的数据：json===》 {"Head":{"TransCode":"X1009","TransId":"20190514145005iQXk"},"Body":{"OrderSN":"95131406006","WHSE":"aaaaa","SNs":[{"SN":"HCMPFD000621"},{"SN":"1212122"}]}}
类似这样。我们要取出来里面特定的值，而且，SNs还是一个集合。
方法如下：
string OrderSn = json["Body"]["OrderSN"].ToString(); string WHSE = json["Body"]["WHSE"].ToString(); string SNs = json["Body"]["SNs"].ToString();
SNs是一个集合，怎么取出来呢：
将json字符串解析为JToken,JObject是JToken的父类，直接使用JToken比较好用
dynamic Sns =JToken.Parse(SNs) as dynamic
for (int i = 0; i < Sns.Count; i++)//获取备注里的SN { if (Sns[i].SN.ToString() != "") { str += Sns[i].SN.ToString() + ","; } }
这样子就可以循环出来里面的值了。
1 HttpWebResponse httpWebResponse = (HttpWebResponse)httpWebRequest.GetResponse(); 2 string response = string.Empty; 3 using (StreamReader reader = new StreamReader(httpWebResponse.GetResponseStream())) 4 response = reader.ReadToEnd(); 5 6 var j = JObject.Parse(response); 7 string shop_name = j["Success"]["items"]["item"][0]["shop_name"].ToString();//独一味日化旗舰店、、、一层层的层级关系{ "Success": { "total_results": "1", "items": { "item": [{ "shop_name": "独一味日化旗舰店", "serial_num": "", "order_channel": "直营网店", "updatetime": "", "总数量": "3739", "maxrowver": "", "tid_item": [{ "storage_id": "1", "tid": "S17fdgfgfg0349", "pro_detail_code": "191", "book_inventory": "-5.000", "store_location": "", "pro_type": "原始产品" }, { "storage_id": "1", "tid": "S1712220000349", "pro_detail_code": "152", "book_inventory": "-4.000", "store_location": "", "pro_type": "原始产品" }] }] } } }
上面这个是其他的厂商返回的一个Json格式的数据，现在可以是Json嵌套的还挺多，其中的一个项次还有数组，现在就是把这些数据捞出来存下来。
var j = JObject.Parse(response); //这个就是主干的值 string shop_name = j["Success"]["items"]["item"][0]["shop_name"].ToString();//独一味日化旗舰店 string tid_item = j["Success"]["items"]["item"][0]["tid_item"].ToString(); //下面是获取数组的名细可以取出来值 JArray jArray = JArray.Parse(tid_item); for (int i = 0; i < jArray.Count; i++) { JObject jdata = (JObject)jArray[i]; string pro_detail_code = jdata["pro_detail_code"].ToString(); }//将数据动态插入到数组中去 JArray jArray = JArray.Parse(tid_item); JArray arr = new JArray(); for (int i = 0; i < jArray.Count; i++) { JObject obj = new JObject(); JObject jdata = (JObject)jArray[i]; obj["linenum"] = jdata["cost_price"].ToString(); obj["sku"] = jdata["sell_price"].ToString(); obj["qty"] = jdata["original_price"].ToString(); obj["inventoryname"] = jdata["sys_price"].ToString(); obj["price"] = jdata["product_name"].ToString(); arr.Add(obj); } var rss = new JObject { {"Head",new JObject { {"TransCode","X1009" }, {"TransId",1212} } }, { "Body", new JObject { {"orderno", "orderno" }, {"billto","billto"}, {"shipto", "shipto"}, {"workid", "workid"}, {"tocity", "tocity"}, {"Address", "Address"}, {"Contact", "Contact"}, {"Tel", "Tel"}, {"detail", arr } } } };
