JQuery 来获取数据c#中的JSON数据

C# 后台 (JSONHandler.ashx)

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

 using System;
 using System.Web;
 using System.Web.Script.Serialization;

 public class JSONHandler : IHttpHandler {

     public void ProcessRequest (HttpContext context) {
         context.Response.ContentType = "text/plain";
         JavaScriptSerializer serializer = new JavaScriptSerializer();
         Person p = new Person();
         p.name = context.Request.QueryString.GetValues("name")[];
         p.age = Convert.ToInt32(context.Request.QueryString["age"]);
         //将p转换成json数据，并输出
         context.Response.Write(serializer.Serialize(p));
     }

     public bool IsReusable {
         get {
             return false;
         }
     }

 }

 /// <summary>
 /// Person类
 /// </summary>
 public class Person
 {
     public string name
     {
         get;
         set;
     }
     public int age
     {
         get;
         set;
     }
 }

JQuery 前台

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