添加Log类

public class Log
    {
        private const string SError = "Error";
        private const string SDebug = "Debug";
        private const string DefaultName = "Info";
        static Log()
        {
            var path = AppDomain.CurrentDomain.BaseDirectory + @"\log4net_config.xml";
            log4net.Config.XmlConfigurator.Configure(new FileInfo(path));
        }
        public static log4net.ILog GetLog(string logName)
        {
            var log = log4net.LogManager.GetLogger(logName);
            return log;
        }
        public static void Debug(string message)
        {
            var log = log4net.LogManager.GetLogger(SDebug);
            if (log.IsDebugEnabled)
                log.Debug(message);
        }
        public static void Debug(string message, Exception ex)
        {
            var log = log4net.LogManager.GetLogger(SDebug);
            if (log.IsDebugEnabled)
                log.Debug(message, ex);
        }
        public static void Error(string message)
        {
            var log = log4net.LogManager.GetLogger(SError);
            if (log.IsErrorEnabled)
                log.Error(message);
        }
        public static void Error(string message, Exception ex)
        {
            var log = log4net.LogManager.GetLogger(SError);
            if (log.IsErrorEnabled)
                log.Error(message, ex);
        }
        public static void Fatal(string message)

        {
            var log = log4net.LogManager.GetLogger(DefaultName);
            if (log.IsFatalEnabled)
                log.Fatal(message);
        }
        public static void Info(string message)
        {
            log4net.ILog log = log4net.LogManager.GetLogger(DefaultName);
            if (log.IsInfoEnabled)
                log.Info(message);
        }
        public static void Warn(string message)

        {
            var log = log4net.LogManager.GetLogger(DefaultName);
            if (log.IsWarnEnabled)
                log.Warn(message);
        }
    }
