『动态』动态JSON万能转换函数 + .Net40 dynamic动态数据绑定

不废话，调用代码：

 1         static void Main(string[] args)
 2         {
 3             string json = File.ReadAllText("2.txt", Encoding.Default);
 4 
 5             object result = JsonConvert.DeserializeObject(json);
 6             //dynamic result = JsonConvert.DeserializeObject<dynamic>(json);  //这行函数 啥用都没有 //虽然 result 是 dynamic 定义, 但其实还是 JObject 类型 —— 这种类型是 Newtonsoft.Json 中的一个实体
 7 
 8             //需要对 动态JSON 进行一个 转换
 9             dynamic result2 = JsonObjectToDynamic(result);
10             dynamic text = result2.DKS.Text;
11             Console.WriteLine(text);
12 
13 
14             //--------------------------------
15             //动态对象 测试
16             dynamic dyna = new DynamicModel();
17             dyna["Name"] = "张三";
18             dyna["Birthday"] = new DateTime(1990, 02, 15);
19 
20             Console.WriteLine(dyna.Name);
21             Console.WriteLine(dyna.Birthday);
22 
23 
24         }

运行截图：
