Я работаю над этим кодом C#, который основан на Windows, теперь требуется преобразовать эту функциональность в службу Windows. Я последовал следующую ссылку из MSDN для моего преобразования подхода:Windows Service C# Issue

Избавления от всех функций формы, я сохранил свою логику неповрежденной, который передает файл доступ и анализирует его в текстовый формат, хотя услуга, кажется, работает но он не работает так же, как win app.

Также были бы полезны любые идеи о том, как регистрировать каждое событие обслуживания.

Для ведения журнала вы можете использовать log4net. http://www.codeproject.com/Articles/14819/How-to-use-log4net –

И каков ваш вопрос? –

Хорошо, так что это не работает. Можете ли вы предоставить более подробную информацию? Что он делает, чего раньше не делал, или не делал этого? – psubsee2003

Вам не нужен веб-сервис для размещения. Все, что вам нужно, это таймер в службе Windows и выполнение вашей задачи каждый раз, когда истекло время. Код службы Windows выглядит следующим образом:

private System.Timers.Timer serviceTimer = new System.Timers.Timer(); 

protected override void OnStart(string[] args) 
{ 
    InitTimer(); 
} 

protected override void OnStop() 
{ 
    serviceTimer.Stop(); 
} 

private void InitTimer() 
{ 
    serviceTimer.Start(); 
    serviceTimer.Enabled = true; 
    serviceTimer.Interval = 5000; 
    serviceTimer.Elapsed += new ElapsedEventHandler(OnServiceTimerElapsed); 
} 

public void OnServiceTimerElapsed(object sender, ElapsedEventArgs args) 
{ 
    serviceTimer.Enabled = false; 
    try 
    { 
     copyej(); 
    } 
    catch(Exception ex) 
    { 
       //Handle exception 
    } 
    finally 
    { 
     serviceTimer.Enabled = true; 
    } 
}

hi venu .. Я получаю ошибку «Имя copyej() не существует в текущем контексте» .. это потому, что функция определена в отдельном классе? – user2385057

yes..you просто скопируйте функцию copyej() в том же классе обслуживания. Он должен работать нормально. –
