.Net Windows服務內存不足異常

Question

請讓我知道如何解決以下錯誤。 僅當代碼在生產機中部署后（即一旦Windows服務啟動並在生產機上運行），才會出現“內存不足”異常。 它不會在我們的本地復制。

Application: LSRAnalysisService.exe
Framework Version: v4.0.30319

我們有一個在Windows服務中運行的計時器。

請在下面找到代碼

        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)
            {

            }

        }
    }
}

在此先感謝您的幫助。

計時器過多：

   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)
    {

    }

}

並在OnStart中調用addTimer。 附：請盡可能避免繼續。 多數時間是這樣。
