您可以使用BackgroundWorker进行线程处理，使用Process.WaitForExit()等待进程终止，直到停止服务为止. br/>
没错，应该做一些线程处理，在OnStart中进行大量工作可能会导致启动服务时无法从Windows正确启动的错误.

You can use a BackgroundWorker for the threading, use Process.WaitForExit() to wait for the process to terminate until you stop your service.

You''re right that you should do some threading, doing lots of work in the OnStart may render errors about not starting correctly from Windows when starting the service.

protected override void OnStart(string[] args) 
{ 
 
    BackgroundWorker bw = new BackgroundWorker(); 
    bw.DoWork += new DoWorkEventHandler(bw_DoWork); 
    bw.RunWorkerAsync(); 
} 
 
private void bw_DoWork(object sender, DoWorkEventArgs e) 
{ 
    Process p = new Process(); 
    p.StartInfo = new ProcessStartInfo("file.exe"); 
    p.Start(); 
    p.WaitForExit(); 
    base.Stop(); 
} 

编辑您可能还希望将Process p移至类成员，然后在OnStop中停止该进程，以确保如果exe出现问题，您可以再次停止该服务.

Edit You may also want to move the Process p to a class member and stop the process in the OnStop to make sure that you can stop the service again if the exe goes haywire.

protected override void OnStop() 
{ 
    p.Kill(); 
}

BackgroundWorker()未声明.那是什么.详细信息可在其中定义RunWorkerAsync()的位置.

仅需几行的任何建议就不需要知道任何可能的代码.如果可以理解的话，那么示例.

BackgroundWorker() is not declared. what is that. where is RunWorkerAsync() defined is detail avail.

any suggestion in just few lines required no Code is necessary just to know how it could be possible. if example then appreciated.
