逻辑

Question

使用窗口服务的C＃我想根据我的配置标签运行的服务，其实我会在这里设定值的app.config中的三个标签下面提到

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

如果假设RUN_NOW值是1，

当服务启动时，它现在要做的工作，并为下一个实例它应该运行基于由SETDAYS标签。

如果假设RUN_NOW值为0，

当服务启动时，它不应该这样做，应该等待工作SETDAYS来，然后下一个实例应该为每一套天标签运行

。

这里下面我已经粘贴代码：

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); 


     } 

所以现在我不得不使用标签帮助RUN_NOW和实现逻辑，请指教如何执行。

Answer 1

试试这个。检查AppSettings

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