newtonsoft.json 序列化，反序列化

public class Book
{
　　public string BookID { get; set; }
　　public DateTime PublishDate { get; set; }
　　public decimal Price { get; set; }

　　public override string ToString()
　　{
　　　　return "ID:" + BookID + "; Date:" + PublishDate.ToShortDateString() + "; Price" + Price.ToString("n");
　　}
}

 Book bk = new Book() { BookID = "12111", PublishDate = DateTime.Parse("2012-2-1 22:12:11"), Price=433.12M};
 Console.WriteLine(JsonConvert.SerializeObject(bk));
 
 string jsonBook = "{'BookID':'123', 'PublishDate':'2011-1-2', 'Price':23.5}";
 Book bk1 = JsonConvert.DeserializeObject<Book>(jsonBook);
 Console.WriteLine(bk1.ToString());
 
a.

using Newtonsoft.Json;
using System.Text;

StringBuilder sb = new StringBuilder();
string str = "[{ID:'1',Name:'John',Other:[{Age:'21',Sex:'0'}]},{ID:'2',Name:'Good',Other:[{Age:'36',Sex:'1'}]}]";
JavaScriptArray javascript = (JavaScriptArray)JavaScriptConvert.DeserializeObject(str);

for (int i = 0; i < javascript.Count; i++ )
{
　　JavaScriptObject obj = (JavaScriptObject)javascript[i];
　　sb.Append("ID：" + obj["ID"].ToString());
　　sb.Append("Name：" + obj["Name"].ToString());
　　JavaScriptArray json = (JavaScriptArray)obj["Other"];

　　for (int j = 0; j < json.Count; j++)

　　　　{
　　　　JavaScriptObject jsonobj = (JavaScriptObject)json[j];
　　　　sb.Append("Age：" + jsonobj["Age"].ToString());
　　　　sb.Append("Sex：" + jsonobj["Sex"].ToString());
　　}
}

b.

string jsonText = "[{'a':'aaa','b':'bbb','c':'ccc'},{'a':'aaa2','b':'bbb2','c':'ccc2'}]";
JsonReader reader = new JsonReader(new StringReader(jsonText));
while (reader.Read())
{
　　textBox1.Text += "TokenType = " + reader.TokenType + " ValueType = " + reader.ValueType + " Value = " + reader.Value + "\r\n";

}

c.定义一个对象:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

/// <summary>
///Customer 的摘要说明
/// </summary>
public class Customer
{
　　//在序列化前后没有变动
　　public string a { get; set; }
　　//在序列化前后设置和重置
　　public string b { get; set; }
　　//设置为null，但在序列化后填充
　　public string c { get; set; }
　　public string Other { get; set; }
　　public Customer()
　　{
　　　　//
　　　　//TODO: 在此处添加构造函数逻辑
　　　　//
　　　　a = "";
　　　　b = "";
　　　　c = "";
　　　　Other = null;
　　}
}

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

string jsonText = "[{'a':'aaa','b':'bbb','c':'ccc'},{'a':'aaa2','b':'bbb2','c':'ccc2'}]";
List<Customer> _list = JsonConvert.DeserializeObject<List<Customer>>(jsonText);
Console.WriteLine(_list[1].a);
foreach (Customer c in _list)
{
　　Console.WriteLine(c.c);
}
