zTree控件的使用

最常用的使用方式是json格式

.net递归实现对象生成json格式字符串

代码：

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.UI;

using System.Web.UI.WebControls;

using Newtonsoft.Json;

using SubSonic;

using System.Data;

using System.Text;

namespace WebApplication1

{

    public partial class Test2 : System.Web.UI.Page

    {

        protected void Page_Load(object sender, EventArgs e)

        {

            if (!IsPostBack)

            {

                ss();

            }

        }

        protected string JsonString { set; get; }

        /* [

       {name:"test1", open:true, children:[

          {name:"test1_1"}, {name:"test1_2"}]},

       {name:"test2", open:true, children:[
