private void WriteLog(string content)        {            try            {                string filePath = System.IO.Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "log/log_win.txt");                content = DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss") + " " + content;                bool append = true;                if (System.IO.File.Exists(filePath) == true)                {                    var fileinfo = new System.IO.FileInfo(filePath);                    if (fileinfo.Length >= 1024 * 1024 * 10) //如果大于等于1M（1024B*1024KB)，则重写日志。                    {                        append = false;                    }                }                var logFileStream = new System.IO.StreamWriter(filePath, append, System.Text.Encoding.UTF8);                logFileStream.WriteLine(content);                logFileStream.Flush();                logFileStream.Close();            }            catch(Exception e)            {                            }                    }
