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？

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我的软件的方法。

写入文件对我来说是个调试问题，因为我不想等到文件刷新到磁盘然后再打开它。

因此我更喜欢它写入控制台。

你有什么建议？

我添加了 app.config 文件并附加了附加内容，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>

最佳答案

您需要在 <root> 中声明两个附加程序部分。

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>
