邏輯

Question

使用窗口服務的C＃我想根據我的配置標籤運行的服務，其實我會在這裏設定值的app.config中的三個標籤下面提到

<add key ="FIREHOST_TIME" value ="5" ></add> 
<add key ="SETDAYS" value ="3" ></add> 
<add key ="RUN_NOW" value ="1" ></add> <!-- 0=no, 1=yes--> 

如果假設RUN_NOW值是1，

當服務啓動時，它現在要做的工作，併爲下一個實例它應該運行基於由SETDAYS標籤。

如果假設RUN_NOW值爲0，

當服務啓動時，它不應該這樣做，應該等待工作SETDAYS來，然後下一個實例應該爲每一套天標籤運行

。

這裏下面我已經粘貼代碼：

protected override void OnStart(string[] args) 
    { 
    DateTime tenAM = DateTime.Today.AddHours(FIREHOST_TIME); 



      if (DateTime.Now > tenAM) 
       tenAM = tenAM.AddDays(SETDAYS); 


      // calculate milliseconds until the next 10:00 AM. 
      int timeToFirstExecution = (int)tenAM.Subtract(DateTime.Now).TotalMilliseconds; 

      // calculate the number of milliseconds in 24 hours. 
      int timeBetweenCalls = (int)new TimeSpan(24, 0, 0).TotalMilliseconds; 

      TimerCallback methodToExecute = kickstart; 

      // start the timer. The timer will execute "ProcessFile" when the number of seconds between now and 
      // the next 10:00 AM elapse. After that, it will execute every 24 hours. 
      System.Threading.Timer timer = new System.Threading.Timer(methodToExecute, null, timeToFirstExecution, timeBetweenCalls); 


     } 

所以現在我不得不使用標籤幫助RUN_NOW和實現邏輯，請指教如何執行。

試試這個。檢查AppSettings

var yourAppKey = ConfigurationManager.AppSettings.Get("RUN_NOW"); 
         or 
var yourAppKey = ConfigurationManager.AppSettings["RUN_NOW"]; 
// do something with yourAppKey
