后台使用类将对象序列化为JSon字符串

 
            $.getJSON("Photolist.ashx",function (msg){
                //每次加载之前清空
                $("#content").html("");
                //动态创建table
                var table=$("<table id='pList'></table>");
                //添加表头
                table.append($("<tr><th>序号</th><th>名字</th><th>照片</th><th>点击次数</th><th>支持</th><th>反对</th><th>时间</th><th>操作</th></tr>"));
                for(var i=0;i<msg.length;i++){
                    var photo=msg[i];
var tr=$("<tr  ></tr>");
                    var td=$("<td>"+(i+1)+"</td>");
                    tr.append(td);
                  var time=new Date().getTime();
                    td=$("<td><a href='DetailPhoto.aspx?).append(table);
            });

cs:

public class Photolist : IHttpHandler {

public void ProcessRequest (HttpContext context) {
        context.Response.ContentType = "text/plain";
        context.Response.Write(GetTable());
    }
protected  string GetTable()
    {
        MyPhotoList.BLL.Photos bll = new MyPhotoList.BLL.Photos();
        List<MyPhotoList.Model.Photos> list = bll.GetModelList("");
        JavaScriptSerializer js = new JavaScriptSerializer();
return js.Serialize(list);

    }

使用之前必须添加命名空间using System.Web.Script.Serialization;
