Log4Net 구성

첫 번째 단계는 Log4Net을 다운로드하는 것입니다.dll
http://download.csdn.net/detail/cpcpc/4011877
2부, 프로필 추가 app.config, 추가 위치는 콘솔 프로그램, Windows 프로그램, Windows 서비스, Asp.Net 웹 사이트, Silverlight

<configuration>
  <configSections>
    <section name="log4net" type="System.Configuration.IgnoreSectionHandler"/>

  </log4net>

</configuration>

세 번째 단계,log4Net을 추가합니다.dll 참조, LogOust 클래스 만들기

public class LogOuts
    {
        public static void Debug(string message)
        {
            log4net.ILog log = log4net.LogManager.GetLogger(MethodBase.GetCurrentMethod().DeclaringType);
            if(log.IsDebugEnabled)
            {
                log.Debug(message);
            }
        }

        public static void Error(string message)
        {
            //log4net.ILog log = log4net.LogManager.GetLogger("log4net");
            log4net.ILog log = log4net.LogManager.GetLogger(MethodBase.GetCurrentMethod().DeclaringType);
            if(log.IsErrorEnabled)
            {
                log.Error(message);
            }
        }

        public static void Fatal(string message)
        {
            log4net.ILog log = log4net.LogManager.GetLogger(MethodBase.GetCurrentMethod().DeclaringType);
            if(log.IsFatalEnabled)
            {
                log.Fatal(message);
            }

        }

        public static void Info(string message)
        {
            //log4net.ILog log = log4net.LogManager.GetLogger("log4net");
            log4net.ILog log = log4net.LogManager.GetLogger(MethodBase.GetCurrentMethod().DeclaringType);
            if(log.IsInfoEnabled)
            {
                log.Info(message);
            }

        }

        public static void Warn(string message)
        {
            log4net.ILog log = log4net.LogManager.GetLogger(MethodBase.GetCurrentMethod().DeclaringType);
            if(log.IsWarnEnabled)
            {
                log.Warn(message);
            }
        }
    }

4단계, LogOuts 클래스가 있는 클래스 라이브러리의Properties 아래의 AssemblyInfo.cs의 추가
WINFORM 응용 프로그램에 [assembly:log4net.Config.DOMConfigurator()] 또는 [assembly:log4net.Config.XmlConfigurator()] WEBFORM에 [assembly:log4net.Config.DOMConfigurator(Config File="web.config", Watch=true)]를 추가할 수 있습니다.
다섯 번째 단계, 호출, 로그 쓰기.로그를 기록해야 하는 곳은 다음과 같이 호출하면 됩니다
LogOuts.Info("로깅 성공!");
