调用：WriteLog("系统错误:" + ex.Message);

        /// <summary>
        /// 记录日志
        /// </summary>
        /// <param name="as_Line"></param>
        private void WriteLog(string as_Line)
        
            LogFileName = LogFolder + "\\\\" + DateTime.Today.ToString("yyyyMMdd") + ".txt";
            if (!Directory.Exists(LogFolder))
            
                Directory.CreateDirectory(LogFolder);
            
            FileStream fs;
            if (!File.Exists(LogFileName))
                fs = new FileStream(LogFileName, FileMode.Create);
            else
                fs = new FileStream(LogFileName, FileMode.Append);
            StreamWriter sw = new StreamWriter(fs);
            sw.WriteLine(System.DateTime.Now.ToString("yyyy/MM/dd HH:mm:ss") + "\\t" + as_Line);
            sw.Flush();
            sw.Close();
            fs.Close();
