接續昨天進度，把最後發送訊息的函式給完成吧！

1. 在Web服務(ASMX)內，於JSON格式轉換的函式後面，再增加發送訊息的函式。

   /// <summary>
   /// 發送LineNotify通知
   /// </summary>
   /// <param name="condition"></param>
   /// <returns></returns>
    [WebMethod(EnableSession = true)]
   public ServiceResultStruct<bool> SendLineNotifyByAlarmSysId(string jsonArray)
   {
       //宣告各項變數
       var condition = JsonDeserialize(jsonArray);     //接收傳入值
       var token = "填入所申請的權杖";  // 參考Day16章節
   
       var result = new ServiceResultStruct<bool>();   //回傳值
       var message = string.Empty;                     //發送訊息
       var stickerPackageId = string.Empty;            //Line貼圖類別
       var stickerId = string.Empty;                   //Line貼圖編號
   
       //判斷傳入的參數是否有值
       if (condition.ContainsKey("message"))
       {
           message = condition["message"].ToString();
       }
       if (condition.ContainsKey("stickerpackageid"))
       {
           stickerPackageId = condition["stickerpackageid"].ToString();
       }
       if (condition.ContainsKey("stickerid"))
       {
           stickerId = condition["stickerid"].ToString();
       }
   
       //使用WebClient發送訊息
       using (var wc = new WebClient())
       {
           //安全性通訊協定，指定 Transport Layer Security (TLS) 1.2 安全性通訊協定
           System.Net.ServicePointManager.SecurityProtocol = System.Net.SecurityProtocolType.Tls12;
           //指定Token(所申請的權杖)
           var bearer = token;
           //宣告編碼為UTF8，並填入指定Token到傳輸參數內
           wc.Encoding = Encoding.UTF8;
           wc.Headers.Add("Content-Type", "application/x-www-form-urlencoded");
           wc.Headers.Add("Authorization", $"Bearer {bearer}");
   
           //宣告NameValueCollection()集合類別，用來儲存字串集合
           var nv = new NameValueCollection();
           nv["message"] = message;                    //訊息文字
           nv["stickerPackageId"] = stickerPackageId;  //貼圖類別
           nv["stickerId"] = stickerId;                //貼圖編號
   
           //指定Line API網址並發送訊息
           var bResult = wc.UploadValues($"https://notify-api.line.me/api/notify", nv);
           //取得執行後回傳結果
           var res = Encoding.UTF8.GetString(bResult);
           //回傳結果宣告為JSON
           var resultjson = JsonDeserialize(res);
           if (resultjson.ContainsKey("status") && Convert.ToInt16(resultjson["status"]) == (byte)EHttpCodeType.成功)
           {
               result.Result = true;
               result.ErrMsg = string.Empty;
               result.Memo = "發送完成";
               result.HttpCode = EHttpCodeType.成功;
               result.Status = true;
           }
           else
           {
               result.Result = false;
               result.ErrMsg = resultjson["message"];
               result.Memo = "發送失敗";
               result.HttpCode = EHttpCodeType.伺服器端程序錯誤;
               result.Status = true;
           }
       }
       return result;
   }
   

如此一來就完成整個後台專案啦！

好的，今天就先到這兒，明天再來繼續吧！
