<%@ WebHandler Language="C#" Class="Handler" %>
using System;
using System.Web;
using System.Web.Script.Serialization;
using System.Collections.Generic;
public class Handler : IHttpHandler {
public void ProcessRequest (HttpContext context) {
context.Response.ContentType = "text/plain";
Person p1 = new Person { Age = "22", Name = "tom" };
Person p2 = new Person { Age = "23", Name = "jim" };
Person p3 = new Person { Age = "24", Name = "lilei" };
IList<Person> persons = new List<Person> {p1,p2,p3};
JavaScriptSerializer js = new JavaScriptSerializer();
string s= js.Serialize(persons);
context.Response.Write(s);
}
public class Person
{
public string Name { get; set; }
public string Age { get; set; }
}
public bool IsReusable {
get {
return false;
}
}
}先实例化了三个person对象，然后放到一个集合中，最后把这个集合序列化成字符串流到客户端;
客户端：

$.get("Handler.ashx", function(data) {
var persons = $.parseJSON(data);
$.each(persons, function(key, person) {
alert("Age:"+person.Age+"Name:"+person.Name) });
});
