   成功的走出第一步后，我们紧接着趁热打铁开始下一步： 

　　成为了开发者之后微信平台会给您AppId和AppSecret，在订阅号中是没有的，所以因该申请一下服务号

　　　　有了ACCESSTOKEN才能做添加菜单，上传/下载图片等功能

　　　　所以这次还要借用一下大哥的代码了，上代码：

    private string GetToken()           {                     // 也可以这样写:               //return  GetPage("https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=你的appid&secret=你的secret", "");                            string res = "";               HttpWebRequest req = (HttpWebRequest)HttpWebRequest.Create("https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential      &appid=你的appid&secret=你的secret");       req.Method = "GET";               using (WebResponse wr = req.GetResponse())               {                   HttpWebResponse myResponse = (HttpWebResponse)req.GetResponse();                               StreamReader reader = new StreamReader(myResponse.GetResponseStream(), Encoding.UTF8);                               string content = reader.ReadToEnd();                            List<ACCESSTOKEN> myACCESSTOKEN = Json.JSONStringToList<ACCESSTOKEN>(content);                   res = myACCESSTOKEN[0].access_token;                      }                          return res;           }           public string GetPage(string posturl, string postData)           {               Stream outstream = null;               Stream instream = null;               StreamReader sr = null;               HttpWebResponse response = null;               HttpWebRequest request = null;               Encoding encoding = Encoding.UTF8;               byte[] data = http://www.mamicode.com/encoding.GetBytes(postData);  "POST";                   request.ContentType = "application/x-www-form-urlencoded";                   request.ContentLength = data.Length;                   outstream = request.GetRequestStream();                   outstream.Write(data, 0, data.Length);                   outstream.Close();                   //发送请求并获取相应回应数据                   response = request.GetResponse() as HttpWebResponse;                   //直到request.GetResponse()程序才开始向目标网页发送Post请求                   instream = response.GetResponseStream();                   sr = new StreamReader(instream, encoding);                   //返回结果网页（html）代码                   string content = sr.ReadToEnd();                   string err = string.Empty;                   return content;               }               catch (Exception ex)               {                   string err = ex.Message;                   Response.Write(err);                   return string.Empty;               }           }

 因为后边的大部分操作基本都要根据你的值来操作的。暂时先写这么多吧，明天继续
