首先添加引用
using Newtonsoft.Json;
示例代碼
dynamic orderJson = new JObject();
//簡(jiǎn)單用法
orderJson.state = "201";
orderJson.msg = "未找到訂單！";
return orderJson.ToString();
//添加子集合
orderJson.ticketlist = new JArray() as dynamic;
dynamic ticketJson = new JObject();
ticketJson.state = "審核中";
orderJson.ticketlist.Add(ticketJson);
return orderJson.ToString();
