当我在 logger.Warn 下执行任何操作时,我想写信给 Console.Out ,然后我想写信给 Console.Err 当我记录任何 logger.Error 及以上。我该如何编写我的log4net配置文件?
到目前为止,我有:
<?xml version="1.0" encoding="utf-8"?>
<log4net>
<appender name="ConsoleAppender" type="log4net.Appender.ConsoleAppender">
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}] - %message%newline" />
</layout>
</appender>
<root>
<level value="DEBUG" />
<appender-ref ref="ConsoleAppender" />
</root>
</log4net>

您可以创建两个appender,并以不同方式配置它们。像(未经测试)的东西:
<log4net>
<appender name="ConsoleOutAppender" type="log4net.Appender.ConsoleAppender">
<filter type="log4net.Filter.LevelRangeFilter">
<levelMin value="DEBUG" />
<levelMax value="WARN" />
</filter>
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="..." />
</layout>
</appender>
<appender name="ConsoleErrorAppender" type="log4net.Appender.ConsoleAppender">
<filter type="log4net.Filter.LevelRangeFilter">
<levelMin value="ERROR" />
<levelMax value="FATAL" />
</filter>
<target value="Console.Error" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="..." />
</layout>
</appender>
<root>
<level value="DEBUG" />
<appender-ref ref="ConsoleOutAppender" />
<appender-ref ref="ConsoleErrorAppender" />
</root>
</log4net>
编辑:更正了levelMin
与levelMax
之间的逻辑错误。
