Log4net

log4net比较流行的一个日志框架

1、程序信息配置里面AssemblyInfo.cs

[assembly: log4net.Config.XmlConfigurator(Watch = true)]

2、配置app.config

配置节点configSections

<configSections>
    <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler log4net"/>
  </configSections>

配置的根节点configuration内

<log4net>
    <appender name="RollingFile" type="log4net.Appender.RollingFileAppender">
      <file type="log4net.Util.PatternString" value="D:PROD_LogsApp_LogsLogsAppALL\%date{yyyy-MM-dd}all_%date{yyyy-MM-dd}.log" />
      <appendToFile value="true" />
      <rollingStyle value="Composite" />
      <datePattern value="yyyy-MM-dd/all_yyyy-MM-dd&quot;.log&quot;" />
      <staticLogFileName value="true" />
      <maximumFileSize value="10MB" />
      <maxSizeRollBackups value="100" />
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%date [%thread] %level %logger [%property{NDC}] - %message%newline" />
      </layout>
    </appender>

    <appender name="TestRollingFile" type="log4net.Appender.RollingFileAppender">
      <file type="log4net.Util.PatternString" value="D:PROD_LogsApp_LogsLogsAppTestALL\%date{yyyy-MM-dd}all_%date{yyyy-MM-dd}.log" />
      <appendToFile value="true" />
      <rollingStyle value="Composite" />
      <datePattern value="yyyy-MM-dd/all_yyyy-MM-dd&quot;.log&quot;" />
      <staticLogFileName value="true" />
      <maximumFileSize value="10MB" />
      <maxSizeRollBackups value="100" />
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%date [%thread] %level %logger [%property{NDC}] - %message%newline" />
      </layout>
    </appender>

    <!--error-->
    <appender name="ErrorRollingFile" type="log4net.Appender.RollingFileAppender">
      <file type="log4net.Util.PatternString" value="D:PROD_LogsApp_LogsLogsApperror\%date{yyyy-MM-dd}error_%date{yyyy-MM-dd}.log" />
      <appendToFile value="true" />
      <rollingStyle value="Composite" />
      <datePattern value="yyyy-MM-dd/error_yyyy-MM-dd&quot;.log&quot;" />
      <staticLogFileName value="false" />
      <maximumFileSize value="10MB" />
      <maxSizeRollBackups value="100" />
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%date [%thread] %level %logger [%property{NDC}] - %message%newline" />
      </layout>
      <filter type="log4net.Filter.LevelMatchFilter">
        <param name="LevelToMatch" value="ERROR" />
      </filter>
      <filter type="log4net.Filter.DenyAllFilter" />
    </appender>

    <logger name="LogsApp.Test">
      <level value="All" />
      <appender-ref ref="TestRollingFile" />
    </logger>

持久服务，日期问题

如果持续性长时间占用的服务类日志，上面配置需要做一定修改

<file type="log4net.Util.PatternString" value="D:PROD_LogsApp_LogsLogsAppTest" />
<datePattern value="yyyy-MM-dd/all_yyyy-MM-dd&quot;.log&quot;" />
<staticLogFileName value="false" />

上面rollingStyle如果不加则按日期也按文件大小分割日志

或者：

[assembly: log4net.Config.XmlConfigurator(ConfigFile = "log4net.config", Watch = true)]

然后把上面的两个配置放入单独的文件中
