日志框架

1、NLog

    <section name="nlog" type="NLog.Config.ConfigSectionHandler, NLog" />
  </configSections>
  <nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd"

 2、Log4Net

<?xml version="1.0"?>
<configuration>
  <configSections>
    <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net"/>
  </configSections>
  <!--日志记录组建配置-->
  <log4net>
    <!-- Console部分log输出格式的设定 -->
    <appender name="ConsoleAppender" type="log4net.Appender.ConsoleAppender">
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="[%-5p]|%d|%logger|[%ndc] %n%m%n" />
      </layout>
    </appender>
    <!-- 日志文件部分log输出格式的设定 -->
    <appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
      <file value="Logs" />
      <!--多线程时采用最小锁定-->
      <lockingModel type="log4net.Appender.FileAppender+MinimalLock"/>
      <!--是否追加到文件,默认为true，通常无需设置-->
      <appendToFile value="true" />
      <rollingStyle value="Date" />
      <!--日期的格式，每天换一个文件记录，如不设置则永远只记录一天的日志，需设置-->
      <datePattern value="yyyyMMdd'.txt'" />
      <staticLogFileName value="false" />
      <layout type="log4net.Layout.PatternLayout">
        <header value="" />
        <!--[%-5p]：日志级别，格式化为5个宽度 [%d]日志时间 [%logger]：日志记录者 [%n]：换行 [%m]：日志内容-->
        <ConversionPattern value="[%-5p]|%d|%logger|[%ndc] %n%m%n%n" />
      </layout>
    </appender>

    <!-- Setup the root category, add the appenders and set the default level -->
    <root>
      <!--控制级别，由低到高: ALL|DEBUG|INFO|WARN|ERROR|FATAL|OFF-->
      <!--比如定义级别为INFO，则INFO级别向下的级别，比如DEBUG日志将不会被记录-->
      <!--如果没有定义LEVEL的值，则缺省为DEBUG-->
      <level value="DEBUG" />
      <!--<appender-ref ref="ConsoleAppender" />-->
      <appender-ref ref="RollingLogFileAppender" />
    </root>
  </log4net>
</configuration>
