Json.Net Demo2
新建一个空的Web项目，名称JsonServer，该网页实现Ajax数据请求和响应。
添加Newtonsoft.Json.dll的Dll引用，添加JQuery API文件，目录结构如下：
新建一个Person类
1 using System; 2 using System.Collections.Generic; 3 using System.Linq; 4 using System.Web; 5 6 /// <summary> 7 ///Person 的摘要说明 8 /// </summary> 9 /// <summary>10 /// 包含用户的基本信息11 /// </summary>12 public class Person13 {14 /// <summary>15 /// 获取或设置用户名16 /// </summary>17 public string Name { get; set; }18 19 /// <summary>20 /// 获取或设置用户年龄21 /// </summary>22 public int Age { get; set; }23 24 /// <summary>25 /// 获取或设置用户性别26 /// </summary>27 public string Gender { get; set; }28 29 /// <summary>30 /// 获取或设置用户国籍31 /// </summary>32 public string Country { get; set; }33 34 /// <summary>35 /// 获取或设置用户电子邮箱36 /// </summary>37 public string Email { get; set; }38 }新建一个数据操作类PersonRepository
1 using System; 2 using System.Collections.Generic; 3 using System.Linq; 4 using System.Web; 5 6 /// <summary> 7 ///Class1 的摘要说明 8 /// </summary> 9 /// <summary>10 /// 用户操作类11 /// </summary>12 public class PersonRepository13 {14 /// <summary>15 /// 获取用户列表16 /// </summary>17 /// <returns>所有用户信息</returns>18 public static List<Person> GetPersons()19 {20 List<Person> ps = new List<Person>();21 Person p1 = new Person { Name = "Tom", Age = 32, Country = "US", Gender = "Male", Email = "tom@gmail.com" };22 Person p2 = new Person { Name = "Jack", Age = 23, Country = "UK", Gender = "Male", Email = "jack@gmail.com" };23 Person p3 = new Person { Name = "Eden", Age = 25, Country = "Canada", Gender = "Female", Email = "eden@gmail.com" };24 Person p4 = new Person { Name = "Li Hua", Age = 29, Country = "China", Gender = "Male", Email = "lihui@163.com" };25 Person p5 = new Person { Name = "Lvo", Age = 40, Country = "US", Gender = "Male", Email = "lvo@gmail.com" };26 ps.Add(p1);27 ps.Add(p2);28 ps.Add(p3);29 ps.Add(p4);30 ps.Add(p5);31 return ps;32 }33 }新建一个一般处理程序PersonHandler
1 <%@ WebHandler Language="C#" Class="PersonHandler" %> 2 3 using System; 4 using System.Web; 5 using System.Collections.Generic; 6 using Newtonsoft.Json; 7 /// <summary> 8 /// 处理用户类的请求 9 /// </summary>10 public class PersonHandler : IHttpHandler11 {12 13 public void ProcessRequest(HttpContext context)14 {15 List<Person> persons = PersonRepository.GetPersons();16 string json = JsonConvert.SerializeObject(persons);17 context.Response.Write(json);18 }19 20 public bool IsReusable21 {22 get23 {24 return false;25 }26 }27 }添加一个Demo.html页面：
