Tcp windows服务没有创建任何日志文件

Question

我创建了一个 Windows 服务，它将打开端口并将数据记录在文本文件中。它是异步数据通信，允许连接多个客户端。但我的问题是它没有创建任何日志文件，也没有记录任何数据。请指导我哪里做错了？？？ 这是我的代码...

        }

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

        public void OnDebug()
        {
            OnStart(null);
        }

        protected override void OnStop()

                writer.WriteLine(Message);
                writer.Close();
            }

现在使用下面的代码，一切正常

  private static void AddtoLogFile(string Message)
    {
        string LogPath = @"D:\Logfile\";
        string filename = "Log_" + DateTime.Now.ToString("dd-MM-yyyy") + ".txt";
        string filepath = LogPath + filename;
        if (File.Exists(filepath))
        {
            using (StreamWriter writer = new StreamWriter(filepath, true))
            {
                writer.WriteLine(Message);
            }
        }
        else
        {
            using (StreamWriter writer = new StreamWriter(filepath, false))
            {
               using(StreamWriter writer1 = File.CreateText(filepath))
                {
                   if(File.Exists(filepath))
                   {
                       writer.WriteLine(Message);
                   }
                }
                //StreamWriter writer1 = File.CreateText(filepath);
                //writer.WriteLine(Message);
            }

谢谢你们……
