log4net的四方常用方式

新年第一篇文章，希望大家喜欢。 

四种常用方式：

1.控制台

2.文件

3.数据库

4.remoting

  </log4net>

其中remoting的方式比较麻烦，在服务端还必须配置：

  <!-- Register a section handler for the log4net section-->
  <configSections >
    <section name ="log4net" type ="System.Configuration.IgnoreSectionHandler" />
  </configSections>
  <!-- This section contains the log4net configuration settings -->
  <log4net >
    <appender name ="ConsoleAppender" type ="log4net.Appender.ConsoleAppender">
      <layout type ="log4net.Layout.PatternLayout">
        <conversionPattern value ="%date [%thread] %-5levele%logger (%property{log4net:HostName}) [%ndc] - %message%newline" />
      </layout>
    </appender>

    <appender name ="LogFileAppender" type ="log4net.Appender.FileAppender">
      <file value ="log-file.txt" />
      <sppendToFile value ="true" />
      <layout type ="log4net.Layout.PatternLayout">
        <header value ="FILE HEADER " />
        <footer value ="FILE FOOTER " />
        <conversionPattern value ="%date [%thread] %-5levele%logger (%property{log4net:HostName}) [%ndc] - %message%newline" />
      </layout>
    </appender>

    <root>
      <level value ="DEBUG" />
      <appender-ref ref ="LogFileAppender" />
    </root>

  </log4net>

<remoting的方式有点小错误，希望知道的同志给点提示！！>
