JObject、JArray对JSON操作

  增删改查：

var cardJson = "['身份证','银行卡','门禁卡']";
            var cardJArray = JArray.Parse(cardJson);

            var p = new Person { Name="fan",Age=12,Dog=new Dog { Name="奶牛"} };
            var pJson = JsonConvert.SerializeObject(p);
            
            JObject jobj = JObject.Parse(pJson);
            
            //添加属性
            jobj["NickName"] = "fan";
            jobj["Wifes"] = new JArray("rose", "lisa");
            ((JArray)jobj["Wifes"]).Add( "july");
            jobj["Cards"] = cardJArray;
            //修改属性
            jobj["Name"] = "li";
            jobj["Age"] = 9;
            jobj["Dog"]["Name"] = "阿黄";
            ((JArray)jobj["Wifes"])[0] = "roses";
            //插入属性
            jobj.Property("Name").AddBeforeSelf(new JProperty("ID", 1));
            //删除属性
            jobj.Property("Age").Remove();
            ((JArray)jobj["Wifes"])[2].Remove();
            //查找
            //遍历属性
            var props = jobj.Children().Values();
            foreach (var prop in props)
            {
                if (!(prop is JObject) && !(prop is JArray))
                {
                    Console.WriteLine(prop.ToString());
                }               
            }
            //遍历数组
            var cardList = ((JArray)jobj["Cards"]);
            foreach (var card in cardList)
            {
                Console.WriteLine(card.ToString());
            }
            //强类型读取
            Console.WriteLine(jobj.Value<int>("ID")); 
            var p2 = jobj.ToString();

对象->JObject->JSON：

var json = new JObject(
        new JProperty("status", result.Status.ToString()),
        new JProperty("results", new JObject(result.Entries.Select(pair =>
            new JProperty(pair.Key, new JObject(
                new JProperty("status", pair.Value.Status.ToString()),
                new JProperty("description", pair.Value.Description),
                new JProperty("data", new JObject(pair.Value.Data.Select(
                    p => new JProperty(p.Key, p.Value))))))))));


var str = json.ToString();

JObject合并：

jObj.Merge(JObject.Parse(userTranslate.ValueJSON));

JObject查找：

jObject.SelectToken($".{path}");//根据路径查找
