我們用到的類庫為：Newtonsoft.Json，通過VS工具中NuGet程序包可以下載。

一：對象轉json-序列化

public class Student{    public int ID { get; set; }    public string Name { get; set; }    public int Age { get; set; }}    //第一種：單一實體類    Student s = new Student();    s.Age = 18;    s.ID = 1;    s.Name = "張三";    string json = Newtonsoft.Json.javaScriptConvert.SerializeObject(s);//序列化對象（對象轉json）    //第二種：List<T>泛型 和上邊方法相同    List<Student> list = new List<Student>();    for (int i = 1; i < 5; i++)    {        Student stu = new Student();        stu.Age = i + 12;        stu.ID = i;        stu.Name = "No."+i.ToString();        list.Add(stu);    }    json = Newtonsoft.Json.JavascriptConvert.SerializeObject(list);

二：json轉對象 - 反序列化

    //json只有一條數據    JavaScriptObject obj = (JavaScriptObject)JavaScriptConvert.DeserializeObject(json);    string Name = obj["Name"].ToString();//取出某一字段    Response.Write(Name);    //json只有一條數據    Student ms = (Student)JavaScriptConvert.DeserializeObject(JavaScriptConvert.SerializeObject(obj), typeof(Student));//json轉對象    Response.Write(ms.Name);    //json有多條數據    JavaScriptArray javascript = (JavaScriptArray)JavaScriptConvert.DeserializeObject(json);    List<Student> slist = new List<Student>();    for (int i = 0; i < javascript.Count; i++)    {        JavaScriptObject temp = (JavaScriptObject)javascript[i];        Student model = (Student)JavaScriptConvert.DeserializeObject(JavaScriptConvert.SerializeObject(temp), typeof(Student));        slist.Add(model);    }

    //4.0方法
    List<Student> slist = JsonConvert.DeserializeObject<List<Student>>(json);
    Response.Write(slist[0].Name);
