记录操作日志

一丶简单的记录操作日志

        public void WriteLog(string msg)
        {
            string filePath = AppDomain.CurrentDomain.BaseDirectory + "Log";
            if (!Directory.Exists(filePath))
            {
                Directory.CreateDirectory(filePath);
            }
            string logPath = AppDomain.CurrentDomain.BaseDirectory + "Log\" + DateTime.Now.ToString("yyyy-MM-dd") + ".txt";
            try
            {
                using (StreamWriter sw = File.AppendText(logPath))
                {
                    sw.WriteLine("消息：" + msg);
                    sw.WriteLine("时间：" + DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss"));
                    sw.WriteLine("**************************************************");
                    sw.WriteLine();
                    sw.Flush();
                    sw.Close();
                    sw.Dispose();
                }
            }
            catch (IOException e)
            {
                using (StreamWriter sw = File.AppendText(logPath))
                {
                    sw.WriteLine("异常：" + e.Message);
                    sw.WriteLine("时间：" + DateTime.Now.ToString("yyy-MM-dd HH:mm:ss"));
                    sw.WriteLine("**************************************************");
                    sw.WriteLine();
                    sw.Flush();
                    sw.Close();
                    sw.Dispose();
                }
            }
        }

 二、

       /// <summary>
        /// 写文件
        /// </summary>
        /// <param name="str"></param>
        static void WriteLog(string str)
        {
            if (!Directory.Exists("ErrLog"))
            {
                Directory.CreateDirectory("ErrLog");
            }

            string logPath ="ErrLog\" + DateTime.Now.ToString("yyyy-MM-dd") + ".txt";

            using (StreamWriter sw = File.AppendText(logPath))
            {
                sw.WriteLine(str);
                sw.WriteLine("---------------------------------------------------------");
                sw.Close();
            }
        }
