留存个备份，简单记录日志的时候用。C#

   
    private object o=new object ();
    private static string getFiles()
        {
            //判断路径、文件是否存在，如不存在则生成相关资源
            string dir = AppDomain.CurrentDomain.BaseDirectory + @"log\";
            if (!Directory.Exists(dir))
            {
                Directory.CreateDirectory(dir);
            }
            //设置文件名
            string currtime = DateTime.Now.ToString("yyyyMM");
            dir += currtime + ".log";
            if (!File.Exists(dir))
            {
                FileStream fs = File.Create(dir);
                fs.Close();
            }
            return dir;
        }
        //写日志
        private static void log(string logstr)
        {
            lock (o)
            {
                string dir = getFiles();
                StreamWriter sw = new StreamWriter(dir, true);
                sw.WriteLine(DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss") + " " + logstr);
                sw.Close();
            }
        }
