newtonsoft动态修改JObject

直接上代码：

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

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

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

            //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);
