How do I configure log4net consoleappender to write to Console.Err and Console.Out based on Level?
提问by Denis
I would like to write to Console.Outwhen I do anything below logger.Warnand then I would like to write to Console.Errwhen I log anything logger.Errorand above. How would I write my log4net config file?
我想写信给Console.Out当我做任何事以下logger.Warn，然后我想写信给Console.Err当我登录任何logger.Error以上。我将如何编写我的 log4net 配置文件？
So far I have:
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>

You can create two appenders, and configure them differently. Something like (untested):
您可以创建两个 appender，并以不同的方式配置它们。类似的东西（未经测试）：
<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>
EDIT: Corrected logic error with levelMinvs. levelMax.
编辑：更正了与levelMinvs. 的逻辑错误levelMax。
