JQuery 来获取数据c#中的JSON数据

C# 后台 (JSONHandler.ashx)

 1 <%@ WebHandler Language="C#" Class="JSONHandler" %>

 3 using System;
 4 using System.Web;
 5 using System.Web.Script.Serialization;

 7 public class JSONHandler : IHttpHandler {
 8     
 9     public void ProcessRequest (HttpContext context) {
10         context.Response.ContentType = "text/plain";
11         JavaScriptSerializer serializer = new JavaScriptSerializer();
12         Person p = new Person();
13         p.name = context.Request.QueryString.GetValues("name")[0];
14         p.age = Convert.ToInt32(context.Request.QueryString["age"]);
15         //将p转换成json数据，并输出
16         context.Response.Write(serializer.Serialize(p));
17     }
18     
19     public bool IsReusable {
20         get {
21             return false;
22         }
23     }
24 
25 }
26 
27 /// <summary>
28 /// Person类
29 /// </summary>
30 public class Person
31 {
32     public string name
33     {
34         get;
35         set;
36     }
37     public int age
38     {
39         get;
40         set;
41     }
42 }

JQuery 前台

 $.getJSON("JSONHandler.ashx", 
    {name:"jack",age:18},
    function (json) {
    var name=json[name];
    var age=json[age];
});
