        public void Save(string message)
        {
            StringBuilder builder = new StringBuilder();
            builder.AppendFormat("日志时间：{0:yyyy-MM-dd HH:mm:ss fff}", DateTime.Now);
            builder.AppendFormat("\r\n日志级别：{0}", "Info");
            builder.AppendFormat("\r\n日志来源：{0}", Environment.GetCommandLineArgs()[0]);
            builder.AppendFormat("\r\n主机名称：{0}", Environment.MachineName);
            builder.AppendFormat("\r\n日志信息：{0}", string.IsNullOrEmpty(message) ? "无" : message);
            lock (lockObj)
            {
                var logFile = @"Logs/" + DateTime.Now.ToString("yyyyMMdd") + ".log";
                logFile = Path.Combine(Environment.CurrentDirectory, logFile);

                //目录不存在时创建目录
                var fileDir = Path.GetDirectoryName(logFile);
                if (!Directory.Exists(fileDir)) Directory.CreateDirectory(fileDir);

                using StreamWriter writer = new StreamWriter(logFile, true, Encoding.Default);
                writer.WriteLine(builder.ToString());
                writer.WriteLine("-----------------------------------");
                writer.Close();
            }
        }

        public void Save(Exception e)
        {
            Save(e.Message + e.StackTrace);
        }
    }
