log4net简单配置打印日志

cs代码应用:

//1.初始状态
log4net.Config.XmlConfigurator.Configure(); 

//2.打印至文件(根据配置文件)
  log4net.ILog logger = log4net.LogManager.GetLogger("Logger");
 logger.Error(“错误日志字符串”);

web.config 配置文件肉容：

<log4net>
    <appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
      <file value="Logs/log.txt"/>
      <appendToFile value="true"/>
      <rollingStyle value="Size"/>
      <maxSizeRollBackups value="10"/>
      <maximumFileSize value="100KB"/>
      <staticLogFileName value="true"/>
      <lockingModel type="log4net.Appender.RollingFileAppender+MinimalLock"/>
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%date [%-5level] %logger - %message%newline"/>
      </layout>
    </appender>
    <!-- Set default logging level -->
    <root>
      <level value="DEBUG"/>
      <appender-ref ref="RollingFileAppender"/>
    </root>
    <!-- Set logging for Spring.Aspects -->
    <logger name="Spring.Aspects">
      <level value="DEBUG"/>
    </logger>
    <!-- Set logging for Spring.Calculator -->
    <logger name="Spring.Calculator">
      <level value="DEBUG"/>
    </logger>
    <!-- Set logging for Spring -->
    <logger name="Spring">
      <level value="INFO"/>
    </logger>
  </log4net>
