在你页面的 Page_Load 函数中调用这个MyMenu()，就可以显示出来了。

既然显示出来了，菜单的时间如何出发呢？我们已经了解到了如果类型为view的话，他有url属性，这个不需要处理，点击后会直接跳转到你设定的url的页面，下面我来看看如何触发click吧，按照微信的文档可以用(!string.IsNullOrEmpty(wx.EventName) && wx.EventName.Trim() == "CLICK")来判断，我把之前的代码改造一下,同时把在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欢迎北京永杰友信科技有限公司/:rose\n直接回复“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,欢迎使用北京永杰友信科技有限公司公共微信平台!");  
             if(wx.EventKey=="P1")  
                 res = sendTextMessage(wx, "你好,点击了产品1");  
             if(wx.EventKey=="P2")  
                 res = sendTextMessage(wx, "你好,点击了产品2");  
         }  
         else  
         {  
             if (wx.MsgType == "text" && wx.Content == "你好")  
             {  
                 res = sendTextMessage(wx, "你好,欢迎使用北京永杰友信科技有限公司公共微信平台!");  
             }  
             else if (wx.MsgType == "voice")  
             {  
                 res = sendTextMessage(wx, wx.Recognition);  
             }  
             else  
             {  
                 res = sendTextMessage(wx, "你好,未能识别消息!");  
             }  
         }  
  
         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>

     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;  
     } 

这样就可以相应你的菜单事件了，我上面的代码写的有很多可以优化的地方，这里主要以简介为主，以后我们会逐渐搭建起一个微信公共平台的.net框架，什么菜单类，消息类等等。
