How to configure log4net to print to console in debug mode
提问by user829174
Is there a way to configure log4net to print logs both to console and to files during debug?
有没有办法配置 log4net 在调试期间将日志打印到控制台和文件？
I am trying to find a way to debug my software efficiently by observing the logs immediately when they happen.
我试图找到一种方法，通过在日志发生时立即观察日志来有效地调试我的软件。
Writing to files is problematic for me for debugging because I don't want to wait until the file is flushed to the disk and then to open it.
写入文件对我进行调试是有问题的，因为我不想等到文件刷新到磁盘然后再打开它。
Therefore I prefer it to write into console.
因此，我更喜欢将其写入控制台。
What do you suggest?
你有什么建议？
I added the app.configfile with the additional appended, but I am not being able to show result console.
我添加了app.config附加附加文件的文件，但我无法显示结果控制台。
Following is my app.config configuration:

You need to have both appenders declared in your <root>section.
您需要在您的<root>部分中声明两个附加程序。
Configure your log4net like this:
像这样配置你的 log4net：
<log4net>
<appender name="Console" type="log4net.Appender.ConsoleAppender">
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date %-5level: %message%newline" />
</layout>
</appender>
<appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
<file value="Log.txt" />
<appendToFile value="false" />
<rollingStyle value="Size" />
<maxSizeRollBackups value="10" />
<maximumFileSize value="50MB" />
<staticLogFileName value="true" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date %-5level[%logger]: %message%newline" />
</layout>
</appender>
<root>
<level value="INFO" />
<appender-ref ref="Console" />
<appender-ref ref="RollingFileAppender" />
</root>
</log4net>

It looks like you've forgotten to hook your appender up to the root logging:
看起来您忘记将附加程序连接到根日志记录：
<root>
<level value="DEBUG" />
<appender-ref ref="RollingLogFileAppender" />
<appender-ref ref="ConsoleAppender" />
</root>
