C#傻瓜日志类

    最近经常做小项目，如果想代码写的靠谱点就必须用到日志，但是常用的日志框架，比如企业库或者log4net都要配置个半天，如果想自定义某个功能也比较麻烦。没办法自己实现了个傻瓜日志类，代码很土鳖，不过简单易改，无配置。

    

    public static class SBLogger
    {
        static SBLogger()
        {
            _LogDir = Path.Combine(AppDomain.CurrentDomain.BaseDirectory,"Log");
            if (!Directory.Exists(_LogDir))
            {
                Directory.CreateDirectory(_LogDir);
            }
        }

        /// <summary>
        /// 写入错误日志
        /// </summary>
        /// <param name="msg"></param>
        /// <param name="args"></param>
        public static void Error(string msg, params object[] args)
        {
            WriteLog("ERROR", msg, args);
        }

        }

                DateTime.Now.ToString("yyyy-MM-dd#HH:mm:ss"),
                type, String.Format(msg, args));
            lock (_WriteMutex)
            {
                File.AppendAllText(GetLogPath(), log, Encoding.UTF8);
            }
        }

        private static string GetLogPath()
        {
            string path = Path.Combine(_LogDir, DateTime.Now.ToString("yyyy-MM-dd") + ".log");
            return path;
        }

        private static string _LogDir = "";
        private static object _WriteMutex = new object();
    }
