用戶自定義菜單制作時,需要用到access_token,我們直接使用前面講解的IsExistAccess_Token()函數。我理解的微信公共平臺里面菜單分為button和sub_button，即菜單和子菜單，這些菜單都有一個name的屬性，類別分為click和view，click類有key屬性；而view類有url屬性，含有子菜單的菜單沒有key屬性也沒有url屬性。這些情況可以從下面的例子看出來。

 public void MyMenu()  {   string weixin1 = "";   weixin1 = @" {  ""button"":[  {    ""type"":""click"",   ""name"":""你好!"",   ""key"":""Hello""  },  {   ""type"":""view"",   ""name"":""公司簡介"",   ""url"":""http://www.4ugood.net""  },  {   ""name"":""產品介紹"",   ""sub_button"":[   {    ""type"":""click"",    ""name"":""產品1"",    ""key"":""P1""   },   {    ""type"":""click"",    ""name"":""產品2"",    ""key"":""P2""   }]  }] }";   string access_token = IsExistAccess_Token();   string i = GetPage("https://api.weixin.qq.com/cgi-bin/menu/create?access_token="+access_token, weixin1);   Response.Write(i);  }

在你頁面的 Page_Load 函數中調用這個MyMenu()，就可以顯示出來了。
既然顯示出來了，菜單的時間如何出發呢？我們已經了解到了如果類型為view的話，他有url屬性，這個不需要處理，點擊后會直接跳轉到你設定的url的頁面，下面我來看看如何觸發click吧，按照微信的文檔可以用(!string.IsNullOrEmpty(wx.EventName) && wx.EventName.Trim() == "CLICK")來判斷，我把之前的代碼改造一下,同時把在GetWxMessage()方法中把EventKey的值附上,wx.EventKey = xml.SelectSingleNode("xml").SelectSingleNode("EventKey").InnerText;  

protected void Page_Load(object sender, EventArgs e)  {     MyMenu();   wxmessage wx = GetWxMessage();   string res = "";   if (!string.IsNullOrEmpty(wx.EventName) && wx.EventName.Trim() == "subscribe")   {    string content = "";    content = "/:rose歡迎北京永杰友信科技有限公司/:rose/n直接回復“你好”";    res = sendTextMessage(wx, content);   }   else if (!string.IsNullOrEmpty(wx.EventName) && wx.EventName.Trim() == "CLICK")   {    if(wx.EventKey=="Hello")     res = sendTextMessage(wx, "你好,歡迎使用北京永杰友信科技有限公司公共微信平臺!");    if(wx.EventKey=="P1")     res = sendTextMessage(wx, "你好,點擊了產品1");    if(wx.EventKey=="P2")     res = sendTextMessage(wx, "你好,點擊了產品2");   }   else   {    if (wx.MsgType == "text" && wx.Content == "你好")    {     res = sendTextMessage(wx, "你好,歡迎使用北京永杰友信科技有限公司公共微信平臺!");    }    else if (wx.MsgType == "voice")    {     res = sendTextMessage(wx, wx.Recognition);    }    else    {     res = sendTextMessage(wx, "你好,未能識別消息!");    }   }   Response.Write(res);  }  private wxmessage GetWxMessage()  {   wxmessage wx = new wxmessage();   StreamReader str = new StreamReader(Request.InputStream, System.Text.Encoding.UTF8);   XmlDocument xml = new XmlDocument();   xml.Load(str);   wx.ToUserName = xml.SelectSingleNode("xml").SelectSingleNode("ToUserName").InnerText;   wx.FromUserName = xml.SelectSingleNode("xml").SelectSingleNode("FromUserName").InnerText;   wx.MsgType = xml.SelectSingleNode("xml").SelectSingleNode("MsgType").InnerText;   if (wx.MsgType.Trim() == "text")   {    wx.Content = xml.SelectSingleNode("xml").SelectSingleNode("Content").InnerText;   }   if (wx.MsgType.Trim() == "event")   {    wx.EventName = xml.SelectSingleNode("xml").SelectSingleNode("Event").InnerText;    wx.EventKey = xml.SelectSingleNode("xml").SelectSingleNode("EventKey").InnerText;   }   if (wx.MsgType.Trim() == "voice")   {    wx.Recognition = xml.SelectSingleNode("xml").SelectSingleNode("Recognition").InnerText;   }      return wx;  }/// <summary>   /// 發送文字消息   /// </summary>   /// <param name="wx">獲取的收發者信息</param>   /// <param name="content">內容</param>   /// <returns></returns>   private string sendTextMessage(wxmessage wx, string content)  {   string res = string.Format(@"<xml>         <ToUserName><![CDATA[{0}]]></ToUserName>         <FromUserName><![CDATA[{1}]]></FromUserName>         <CreateTime>{2}</CreateTime>         <MsgType><![CDATA[text]]></MsgType>         <Content><![CDATA[{3}]]></Content>         </xml> ",    wx.FromUserName, wx.ToUserName, DateTime.Now, content);   return res;  }
