jquery解析json的问题？

json来源于一个ashx文件，名称为:cs.ashx,需要参数：count,indexpagejson的示例代码为：
{ "bh":"12791126","cfd":"聊城","ddd":"","hwmc":"","yslx":"","yl":"","xxyxq":"","lxxm":"","xiaohao":"","lxdh":"","lxdh2":"","sm":"","sj":"2011-8-25 16:30:00","tjip":"","lx":"货源","cph":"","cllx":"","cc":"","zz":"","xqcl":"","UserID":"","bhYuan":"115617","qh":"1337","nr":"茌平发海宁 25吨今订明装黄岛回茌平重货随便装 80元吨常州回茌平 3吨占3米空","dh":"063513375602219","laiyuan":"wd "},
{ "bh":"12791125","cfd":"连云港","ddd":"","hwmc":"","yslx":"","yl":"","xxyxq":"","lxxm":"","xiaohao":"","lxdh":"","lxdh2":"","sm":"","sj":"2011-8-25 16:30:00","tjip":"","lx":"货源","cph":"","cllx":"","cc":"","zz":"","xqcl":"","UserID":"","bhYuan":"115616","qh":"1515","nr":"金华磐安 17立方今订明装有车速联系 15150911698 85708859 13327871128","dh":"15150911698 85708859 13327871128","laiyuan":"wd "},
,
如何在aspx页面中解析这段json，并显示到UL中？

要是是利用javascript转换的话，用eval("("+json+")");
c#的话推荐用Newtonsoft.Json这个组件进行转换成List或Dictionary之类的，或者用c#自带的个操作json数据的组件。
是解析获取到的JSON，不是生成JSON。
js : 用new Function , eval
jquery: jQuery.post(url, [data], [callback], [type]),type 可以指定为json,直接帮你转换了

把下面这句去掉吧，测试用的：alert(jsonArr[0].length);
如果请求的格式为json，则jquery会自动转换，如果请求的格式是字符串使用一楼的做法，转换为对象
简单示例，一组json格式数据protected void Page_Load(object sender, EventArgs e)
        {
            Response.ContentType = "appliction/json";            Response.Write("{");
            Response.Write("recoreds:[");
            Response.Write("{id:13234,isbn:7030122534,title:'JAVA初级教程',unitprice:'100'},");
            Response.Write("{id:13234,isbn:7030122534,title:'JAVA初级教程',unitprice:'100'},");
            Response.Write("{id:13234,isbn:7030122534,title:'JAVA初级教程',unitprice:'100'}");
            Response.Write("]");
            Response.Write("}");
            Response.End();
        }获取数据：<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml">

var json = "//传入的json"
for(var key in json){
    alert(json[key]);
}
获得每一个key的值
alert(key);
获得每一个key的键值
JSON.parse("要解析的JSON字符串");
