微信開發 回覆用戶消息 .net C#

前段時間開發了公司的微信

 這裏作個知識總結分享下經驗，望一塊兒學習。。。。。

 感受後面寫個系列的最好了 。。。。

 企業需求：

     給指定企業用戶發送消息：如考勤信息、 企業通知、我的信息推送等等, 

  

   /// </summary>
        /// <param name="UserID">要發送的人ID</param>
        /// <param name="StrMessg">消息</param>

            string Access_Token = Como.GetAccessToken.GetAccess_token();
            if (Access_Token == "")
                Como.LogUtil.WriteException("SendMessage 未能成功加載Access_Token");
            string Text = @"{
   ""touser"":";

  參數引用詳解：

       1.Como.GetAccessToken.GetAccess_token()   //獲取 Access_token

       2.GetPage  //返回頁面請求信息 結果

 以上爲基礎發送關鍵代碼：
