**一、说明**

1.Newtonsoft.Json 中的Linq To Json中提供了方便的json数据查询、修改等操作。

例如：JObject，JArray

2.在JObject.FromObject()或JArray.FromObject()中也提供了对dynamic类型的支持。

**二、dynamic转json字符串处理**

using Newtonsoft.Json;
    using Newtonsoft.Json.Linq;

1.使用JObject对象

dynamic obj = new JObject();
    obj.name = "张三丰";
    obj.age = 10;
    obj.birthday = DateTime.Now;
    
    Console.WriteLine(obj.ToString());

输出结果：

{
      "name": "张三丰",
      "age": 10,
      "birthday": "2017-07-29T16:39:47.4549601+08:00"
    }

2.使用JObject.FromObject()

dynamic obj = new System.Dynamic.ExpandoObject();
    obj.name = "张三丰";
    obj.age = 10;
    obj.birthday = DateTime.Now;
    
    string result = JObject.FromObject(obj).ToString();
    Console.WriteLine(result);

输出结果：同上

**三、将json字符串发序列化为dynamic类型**

string json = @"
                {
                'Title': 'Json.NET is awesome!',
                'Author': {
                    'Name': 'James Newton-King',
                    'Twitter': '@JamesNK',
                    'Picture': '/jamesnk.png'
                },
                'Date': '2013-01-23T19:30:00',
                'BodyHtml': '<h3>Title!</h3>\r\n<p>Content!</p>'
                }
            ";
    dynamic blogPost = JObject.Parse(json);
    string title = blogPost.Title;
    Console.WriteLine(title);      //输出：Json.NET is awesome!
    Console.WriteLine(blogPost.Date); //输出：2013/1/ 23 19:30:00
