1.通过代码进行配置

1.1代码

http://stackoverflow.com/questions/16336917/can-you-configure-log4net-in-code-instead-of-using-a-config-file

 public class Logger
    {
        public static void Setup()
        {
            Hierarchy hierarchy = (Hierarchy) LogManager.GetRepository();

            PatternLayout patternLayout = new PatternLayout();
            patternLayout.ConversionPattern = "%date [%thread] %-5level %logger - %message%newline";
            patternLayout.ActivateOptions();

            RollingFileAppender roller = new RollingFileAppender();
            roller.AppendToFile = false;
            roller.File = @"Logs\EventLog.txt";
            roller.Layout = patternLayout;
            roller.MaxSizeRollBackups = 5;
            roller.MaximumFileSize = "1GB";
            roller.RollingStyle = RollingFileAppender.RollingMode.Size;
            roller.StaticLogFileName = true;
            roller.ActivateOptions();
            hierarchy.Root.AddAppender(roller);

            MemoryAppender memory = new MemoryAppender();
            memory.ActivateOptions();
            hierarchy.Root.AddAppender(memory);

            hierarchy.Root.Level = Level.Info;
            hierarchy.Configured = true;
        }
    }

 1.2代码调用

1.2.1 在程序启动的时候，调用  Logger.Setup();

1.2.2 输出日志

private static void Application_ThreadException(object sender,ThreadExceptionEventArgs e)
        {
            var logger = LogManager.GetLogger(sender.GetType());
            logger.Error("Error", e.Exception);
            MessageBox.Show(e.Exception.Message);
        }

 

2.通过配置文件进行配置 

2.1配置文件内容

  <configSections>
    <section name ="log4net" type ="System.Configuration.IgnoreSectionHandler"/>
  </configSections>
  <log4net>
    <appender name="errorAppender" type="log4net.Appender.RollingFileAppender">
      <filter type="log4net.Filter.LevelMatchFilter">
        <levelToMatch value="ERROR" />
      </filter>
      <filter type="log4net.Filter.DenyAllFilter" />
      <File value="Logs\err.log" />
      <PreserveLogFileNameExtension value="true" />
      <appendToFile value="true" />
      <rollingStyle value="Date" />
      <datePattern value="yyyyMMdd" />
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%date [%thread] %-5level %logger - %message%newline" />
      </layout>
    </appender>
    <appender name="infoAppender" type="log4net.Appender.RollingFileAppender">
      <filter type="log4net.Filter.LevelMatchFilter">
        <levelToMatch value="INFO" />

      <rollingStyle value="Date" />
      <datePattern value="yyyyMMdd" />
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%date [%thread] %-5level %logger - %message%newline" />
      </layout>
    </appender>
    <appender name="debugAppender" type="log4net.Appender.RollingFileAppender">
      <filter type="log4net.Filter.LevelMatchFilter">
        <levelToMatch value="DEBUG" />
      </filter>
      <filter type="log4net.Filter.DenyAllFilter" />
      <File value="Logs\debug.log" />
      <PreserveLogFileNameExtension value="true" />
      <appendToFile value="true" />
      <rollingStyle value="Date" />
      <datePattern value="yyyyMMdd" />
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%date [%thread] %-5level %logger - %message%newline" />
      </layout>
    </appender>
    <appender name="perfAppender" type="log4net.Appender.RollingFileAppender">
      <filter type="log4net.Filter.LevelMatchFilter">
        <levelToMatch value="INFO" />
      </filter>
      <filter type="log4net.Filter.DenyAllFilter" />
      <File value="Logs\perf.log" />
      <PreserveLogFileNameExtension value="true" />
      <appendToFile value="true" />
      <rollingStyle value="Date" />
      <datePattern value="yyyyMMdd" />
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%date %logger - %message%newline" />
      </layout>
    </appender>
    <root>
      <level value="ALL" />
      <appender-ref ref="errorAppender" />
      <appender-ref ref="infoAppender" />
      <appender-ref ref="debugAppender" />
    </root>
    <logger name="Performance" additivity="false">
      <level value="ALL" />
      <appender-ref ref="perfAppender" />
    </logger>
  </log4net>

需要注意

XmlConfigurator.Configure();这个不带参数的用法，需要研究一下
