newtonsoft动态修改JObject

            var data = new
            {
                mobile = "18888888888",
                company = "1",
                isTravel = "1",
                invoiceId = "1",
                serialId = "fd580000000f670"
            };

            var str = Newtonsoft.Json.JsonConvert.SerializeObject(data);

            //动态添加memberId
            var obj = JObject.Parse(str);
            obj.Add("memberId", "123456789");

            //动态添加clientInfo，这个clientInfo下面又有一级对象
            JObject jObject = new JObject();
            jObject.Add("VersionNumber", "1.4.1");
            obj.Add("clientInfo", jObject);

            var result = obj.ToString();
            Console.WriteLine(result);
