Question

有没有办法配置log4net以在调试期间将日志打印到控制台和文件？

我正在尝试通过在日志发生时立即观察日志来找到一种有效调试软件的方法。

写入文件对我来说是有问题的，因为我不想等到文件被刷新到磁盘然后打开它。

因此我更喜欢它写入控制台。

你有什么建议？

我添加了附加附加的app.config文件，但我无法显示结果控制台。

以下是我的app.config配置：

<?xml version="1.0"?>
<configuration>
  <configSections>
    <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />
  </configSections>

您需要在<root>部分声明两个appender。

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>

Answer 2

看起来你忘了把你的appender挂钩到root日志：

<root>
  <level value="DEBUG" />
  <appender-ref ref="RollingLogFileAppender" />
  <appender-ref ref="ConsoleAppender" />
</root>
