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")[0];
        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];
});
