Log4net 乱码问题解决

在将log4net输出到UdpAppender会出现乱码问题，当然，丢到第三方日志分析工具glaylog下，也出现中文乱码。

<?xml version="1.0"?>
<configuration>
  <configSections>
    <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />
  </configSections>
  <log4net>
    <appender name="UdpAppender" type="log4net.Appender.UdpAppender">
      <param name="Encoding" value="utf-8" />
      <remoteAddress value="192.168.1.43" />
      <remotePort value="12201" />
      <layout type="log4net.Layout.PatternLayout" value="%-5level %logger %message %username %date{yyyyMMdd HH:mm:ss fff} "/>
    </appender>
    <root>
      <level value="ALL" />
      <appender-ref ref="ColoredConsoleAppender" />
      <appender-ref ref="UdpAppender" />
    </root>

    <logger name="*">
      <level value="ALL" />
      <appender-ref ref="UdpAppender" />
    </logger>
  </log4net>
</configuration>

上面的配置中，加上了<param name="Encoding" value="utf-8" />  问题解决！
