asp.net 之微信自定义菜单创建

前段时间由于公司需要，申请了大批量的微信公众账号，并要求每个公众账号都需要创建自定义菜单，由于数量相当庞大，单个创建简直是个巨大的工作量，于是我开动脑筋，搞了一个自义定菜单管理后台，实现一键添加、删除自定义菜单：

• 管理后台是基于asp.net+MVC+dwz来写，至于什么是dwz自己百度，很简单也很实用的国产开源框架
  -公众账号列表页面：

-公众号列表为了展示所有需要创建自定义菜单的公众账号，每条数据都加了复选框，允许多个账号同时创建菜单
创建菜单按钮事件控制器：

public ActionResult CreateMenu(string s1 = "")        {            DWZJson djson = null;            if (string.IsNullOrWhiteSpace(s1))            {                djson = new DWZJson() { message = "请选择要创建菜单的公众号", statusCode = "300" };                return Content(djson.ToJsonString());            }            //string[] ids = s1.Split(new char[1] { ',' }, StringSplitOptions.RemoveEmptyEntries);            //获取选中的公众账号名称            DataTable dt_accout = DALWeiXin.GetAccountList(s1);            StringBuilder sb = new StringBuilder();            if (dt_accout != null && dt_accout.Rows.Count > 0)            {                for (int i = 0; i < dt_accout.Rows.Count; i++)                {                    sb.AppendFormat("<li class='{0}' style=\"display: inline; margin-right: 10px;\"><strong>☑&nbsp;{1}</strong></li>", dt_accout.Rows[i]["ID"], HttpUtility.HtmlDecode(Convert.ToString(dt_accout.Rows[i]["AccountName"])));                }            }            ViewData["AccountList"] = sb.ToString();            //所有菜单列表            DataTable dt = DALWeiXin.getMenuList();            ViewBag.Table = dt;            ViewBag.accountID = s1;//对应公众账号id            return View();        }

选择之后弹出菜单选择窗口，菜单以树形结构分两级展示，根据直观
