我正在尝试从错误中获取输出,以便在附加的日志文件中以及调试窗口中显示。日志文件的内容工作正常,但调试窗口中没有显示任何内容。
首先,这是我的配置
<log4net>
<!--
This writes the log information to the console window. It only logs events
that are at least at the INFO level (which would mean that DEBUG events are not
captured.
-->
<appender name="ConsoleAppender" type="log4net.Appender.ConsoleAppender">
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date{ABSOLUTE} [%thread] %level %logger - %message%newlineExtra Info: %property{testProperty}%newline%exception"/>
</layout>
<filter type="log4net.Filter.LevelRangeFilter">
<levelMin value="DEBUG"/>
<levelMax value="FATAL"/>
</filter>
</appender>
<!--
This stores information in the logfile.txt file. It only captures log events
that contain the key word test or error.
-->
<appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
<file value="C:\TOPS\LOGFILES\logfile.txt"/>
<appendToFile value="true"/>
<rollingStyle value="Size"/>
<maxSizeRollBackups value="5"/>
<maximumFileSize value="10MB"/>
<staticLogFileName value="true"/>
<filter type="log4net.Filter.StringMatchFilter">
<stringToMatch value="test"/>
</filter>
<filter type="log4net.Filter.StringMatchFilter">
<stringToMatch value="error"/>
</filter>
<filter type="log4net.Filter.DenyAllFilter"/>
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %level %logger - %message%newline%exception"/>
</layout>
</appender>
<root>
<level value="DEBUG"/>
<appender-ref ref="ConsoleAppender"/>
<appender-ref ref="RollingFileAppender"/>
</root>
</log4net>
然后我在我的代码中调用log4net
log.Debug("Debug error logging", ex);
log.Info("Info error logging", ex);
log.Warn("Warn error logging", ex);
log.Error("Error error logging", ex);
log.Fatal("Fatal error logging", ex);
这会在我的日志文件中创建5个条目,但在我的控制台窗口中没有条目。
我也修改了我的web.config,所以appender尽可能相似,但我仍然得到完全相同的结果

</appender>

</layout>
</appender>
<root>
<level value="DEBUG"/>
<appender-ref ref="ConsoleAppender"/>
<appender-ref ref="RollingFileAppender"/>
</root>
</log4net>
我可能错过的任何想法都打破了控制台输出?
编辑:
找到了解决方案,正如下面的评论中指出的那样,make3。我混淆了控制台appender和跟踪appender,这是我实际上正在寻找的。这是更新的配置。
