微信自定义菜单（创建和删除）

微信自定义菜单这个就比较简单，直接贴代码。

微信说的注意：

目前自定义菜单最多包括3个一级菜单，每个一级菜单最多包含5个二级菜单。一级菜单最多4个汉字，二级菜单最多7个汉字，多出来的部分将会以“...”代替。请注意，创建自定义菜单后，由于微信客户端缓存，需要24小时微信客户端才会展现出来。建议测试时可以尝试取消关注公众账号后再次关注，则可以看到创建后的效果。 

        #region 菜单管理
        public ActionResult CreateMenu()
        {
            string access_token = weixin.AccessToken();
            string url = "https://api.weixin.qq.com/cgi-bin/menu/create?access_token=" + access_token;
            string data = "";

            using (StreamReader sr = new StreamReader(Server.MapPath("/Config/menu.txt")))
            {
                data = sr.ReadToEnd();
            }


            var json = HttpHelper.Post(url, data);
            return Content(json);
        }

        public ActionResult DeleteMenu()
        {
            string access_token = weixin.AccessToken();
            string url = "https://api.weixin.qq.com/cgi-bin/menu/delete?access_token=" + access_token;

            var json = HttpHelper.Get(url);
            return Content(json);
        }
        #endregion

返回结果

正确时的返回JSON数据包如下：

{"errcode":0,"errmsg":"ok"}

错误时的返回JSON数据包如下（示例为无效菜单名长度）：

{"errcode":40018,"errmsg":"invalid button name size"}
