.Net Windows服務內存異常

Question

請讓我知道如何解決以下錯誤。內存溢出僅在生產計算機中部署代碼後纔會發生（即一旦Windows服務在生產計算機上啓動並運行）。它不是在我們當地的複製品。

Application: LSRAnalysisService.exe 
Framework Version: v4.0.30319

我們有一個定時器在windows服務中運行。

請提前發現你的幫助下

 protected override void OnStart(string[] args) 
     { 
      if (wcfserviceHost != null) 
       wcfserviceHost.Close(); 
      wcfserviceHost = new ServiceHost(typeof(AnalysisManager)); 
      wcfserviceHost.Open(); 
      Deletefile(); 
     } 

     protected void timer_Elapsed(object sender, System.Timers.ElapsedEventArgs e) 
     { 
      Deletefile(); 
     } 

     private void Deletefile() 
     { 
      try 
      { 
       timer = new System.Timers.Timer(); 
       timer.Interval = (1000) * 60 * 60;//(10000) * 6; 
       timer.Elapsed += new System.Timers.ElapsedEventHandler(timer_Elapsed); 
       string FilePath = System.Configuration.ConfigurationSettings.AppSettings["FilePath"]; 
       DirectoryInfo dirInfo = new DirectoryInfo(FilePath); 
       foreach (DirectoryInfo subDirectory in dirInfo.GetDirectories()) 
       { 
        if (subDirectory.Name == "Temp") continue; 
        if (subDirectory.CreationTime < DateTime.Now.AddDays(-1)) 
        { 
        subDirectory.Delete(true); 
        } 
       } 
       timer.Enabled = true; 
       timer.Start(); 
      } 
      catch(Exception ex) 
      { 

      } 

     } 
    } 
} 

感謝代碼。

太多的計時器：

private void addtimer() 
{ 
    timer = new System.Timers.Timer(); 
    timer.Interval = (1000) * 60 * 60;//(10000) * 6; 
    timer.Elapsed += new System.Timers.ElapsedEventHandler(timer_Elapsed); 
    timer.Enabled = true; 
    timer.Start(); 

} 
protected void timer_Elapsed(object sender, System.Timers.ElapsedEventArgs e) 
{ 
    Deletefile(); 
} 
private void Deletefile() 
{ 
    try 
    { 
     string FilePath = System.Configuration.ConfigurationSettings.AppSettings["FilePath"]; 
     DirectoryInfo dirInfo = new DirectoryInfo(FilePath); 
     foreach (DirectoryInfo subDirectory in dirInfo.GetDirectories()) 
     { 
      if (subDirectory.Name != "Temp" && subDirectory.CreationTime < DateTime.Now.AddDays(-1)) 
       subDirectory.Delete(true); 
     } 
    } 
    catch (Exception ex) 
    { 

    } 

} 

和處理通信呼叫addTimer。 Ps：避免在可能時繼續下去。大部分時間都是這樣。
