如何將log4net配置爲以調試模式打印到控制檯

Question

有沒有辦法將log4net配置爲在調試期間將日誌打印到控制檯和文件？

我試圖通過在發生日誌時立即觀察日誌來高效地調試我的軟件。

對於我來說，寫入文件對於調試是有問題的，因爲我不想等到文件刷新到磁盤然後再打開它。

因此，我更喜歡它寫入控制檯。

你有什麼建議？

我添加了app.config文件和附加的附件，但我無法顯示結果控制檯。

以下是我的app.config配置：

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

Answer 1

你需要有兩個附加目的地聲明在你的<root>部分。

配置您的log4net的是這樣的：

<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

它看起來像你忘了你的掛鉤附加目的地到根日誌記錄：

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