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
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web; /// <summary>
///Person 的摘要说明
/// </summary>
/// <summary>
/// 包含用户的基本信息
/// </summary>
public class Person
{
/// <summary>
/// 获取或设置用户名
/// </summary>
public string Name { get; set; } /// <summary>
/// 获取或设置用户年龄
/// </summary>
public int Age { get; set; } /// <summary>
/// 获取或设置用户性别
/// </summary>
public string Gender { get; set; } /// <summary>
/// 获取或设置用户国籍
/// </summary>
public string Country { get; set; } /// <summary>
/// 获取或设置用户电子邮箱
/// </summary>
public string Email { get; set; }
}
Person
新建一个数据操作类PersonRepository
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web; /// <summary>
///Class1 的摘要说明
/// </summary>
/// <summary>
/// 用户操作类
/// </summary>
public class PersonRepository
{
/// <summary>
/// 获取用户列表
/// </summary>
/// <returns>所有用户信息</returns>
public static List<Person> GetPersons()
{
List<Person> ps = new List<Person>();
Person p1 = new Person { Name = "Tom", Age = , Country = "US", Gender = "Male", Email = "tom@gmail.com" };
Person p2 = new Person { Name = "Jack", Age = , Country = "UK", Gender = "Male", Email = "jack@gmail.com" };
Person p3 = new Person { Name = "Eden", Age = , Country = "Canada", Gender = "Female", Email = "eden@gmail.com" };
Person p4 = new Person { Name = "Li Hua", Age = , Country = "China", Gender = "Male", Email = "lihui@163.com" };
Person p5 = new Person { Name = "Lvo", Age = , Country = "US", Gender = "Male", Email = "lvo@gmail.com" };
ps.Add(p1);
ps.Add(p2);
ps.Add(p3);
ps.Add(p4);
ps.Add(p5);
return ps;
}
}
PersonRepository
新建一个一般处理程序PersonHandler
<%@ WebHandler Language="C#" Class="PersonHandler" %> using System;
using System.Web;
using System.Collections.Generic;
using Newtonsoft.Json;
/// <summary>
/// 处理用户类的请求
/// </summary>
public class PersonHandler : IHttpHandler
{ public void ProcessRequest(HttpContext context)
{
List<Person> persons = PersonRepository.GetPersons();
string json = JsonConvert.SerializeObject(persons);
context.Response.Write(json);
} public bool IsReusable
{
get
{
return false;
}
}
}
PersonHandler
添加一个Demo.html页面：

<body> <div>
<table border="">

<tbody id="personBody">

</div> <script src="Scripts/jquery-1.4.1.min.js" type="text/javascript"></script>
<script type="text/javascript">
$(function () {
$.getJSON("PersonHandler.ashx", function (data, status) {
if (status == "success") {
$.each(data, function (index, item) {
var beginTag = "<tr><td>";
var endTag = "</td></tr>";
var tag = "</td><td>";
$("#personBody").append($(beginTag + item.Name + tag + item.Age + tag + item.Gender + tag
+ item.Country + tag + item.Email + endTag));
});
}
});
});
</script> </body>
</html>
