Asp.net 利用微软的自带方法 object to json

<%@ WebHandler Language="C#" Class="pie1" %>

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

public class pie1 : IHttpHandler {

    YouDaoLv bll = new YouDaoLv();
    public void ProcessRequest (HttpContext context) {
        context.Response.ContentType = "text/plain";
        DateTime sD = context.Request["s"] == null ? new DateTime(1900, 1, 1) : Convert.ToDateTime(context.Request["s"]);
        DateTime eD = context.Request["e"] == null ? new DateTime(1900, 1, 1) : Convert.ToDateTime(context.Request["e"]);
        string pCode = context.Request["pCode"] == null ? string.Empty : context.Request["pCode"];

        ArrayList datalist = new ArrayList();
        List<YoudaolvDetail> list = new List<YoudaolvDetail>();
        list = bll.GetPieData(sD, eD, pCode).OrderByDescending(m=>m.YoudaoNum).ToList();

        JavaScriptSerializer json = new JavaScriptSerializer();
        string a = json.Serialize(list);

        context.Response.Clear();
        context.Response.Write(a);
        context.Response.End();
    }
 
    public bool IsReusable {
        get {
            return false;
        }
    }

}

序列化 后结果:
