【问题描述】：

我正在构建一个应用程序，我需要在其中记录不同的内容，例如应用程序行为（打开/关闭窗口、异常、警告等...）和数据读/写（csv 格式）我有这个 log4net.config 文件

<log4net>
        <root>
            <level value="ALL" />
            <appender-ref ref="ApplicationLog" />
            <appender-ref ref="DigitalWriteLog" />
            <appender-ref ref="AnalogWriteLog" />
            <appender-ref ref="AnalogReadLog" />
        </root>
        <appender name="ApplicationLog" type="log4net.Appender.FileAppender">
            <file value="Application.log" />
            <appendToFile value="true" />
            <staticLogFileName value="true" />
            <lockingModel type="log4net.Appender.FileAppender+MinimalLock"/>
            <preserveLogFileNameExtension value="true" />
            <layout type="log4net.Layout.PatternLayout">
                <conversionPattern value="%date [%thread] %level %logger - %message%newline" />
            </layout>
        </appender>
        <appender name="DigitalWriteLog" type="log4net.Appender.RollingFileAppender">
            <lockingModel type="log4net.Appender.FileAppender+MinimalLock"/>
            <file value="DigitalWrite/" />
            <appendToFile value="true" />
            <datePattern value="dd-MM-yyyy'.csv'" />
            <staticLogFileName value="false" />
            <preserveLogFileNameExtension value="true" />
            <rollingStyle value="Date" />
            <layout type="log4net.Layout.PatternLayout">
                <conversionPattern value="%message%newline" />
            </layout>
        </appender>
        <appender name="AnalogWriteLog" type="log4net.Appender.RollingFileAppender">
            <lockingModel type="log4net.Appender.FileAppender+MinimalLock"/>
            <file value="AnalogWrite/" />
            <appendToFile value="true" />
            <datePattern value="dd-MM-yyyy'.csv'" />
            <staticLogFileName value="false" />
            <preserveLogFileNameExtension value="true" />
            <rollingStyle value="Date" />
            <layout type="log4net.Layout.PatternLayout">
                <conversionPattern value="%message%newline" />
            </layout>
        </appender>
        <appender name="AnalogReadLog" type="log4net.Appender.RollingFileAppender">
            <lockingModel type="log4net.Appender.FileAppender+MinimalLock"/>
            <file value="AnalogRead/" />
            <appendToFile value="true" />
            <datePattern value="dd-MM-yyyy'.csv'" />
            <staticLogFileName value="false" />
            <preserveLogFileNameExtension value="true" />
            <rollingStyle value="Date" />
            <layout type="log4net.Layout.PatternLayout">
                <conversionPattern value="%message%newline" />
            </layout>
        </appender>
    </log4net>

我使用这段代码来实例化日志

    private static readonly ILog applicationLog = LogManager.GetLogger("ApplicationLog");
    private static readonly ILog digitalWriteLog = LogManager.GetLogger("DigitalWriteLog");
    private static readonly ILog analogWriteLog = LogManager.GetLogger("AnalogWriteLog");
    private static readonly ILog analogReadLog = LogManager.GetLogger("AnalogReadLog");

并像这样使用它

    applicationLog.Info("Some info");
    digitalWriteLog(String.Format("Some digital write csv"));
    analogWriteLog(String.Format("Some analog write csv"));
    digitalReadLog(String.Format("Some analog read csv"))

但是当我去检查 .csv 文件时，它们有完整的日志，而不是单独的消息。

        =============  Started Logging  =============        
Opening main window

15:49:56,6,250,1.575,000,700,000,700,000,562,500,1.409,335,1.480,509

Closing main window
        =============  Ended Logging  =============

什么时候应该用于 AnalogReadLog

15:49:56,6,250,1.575,000,700,000,700,000,562,500,1.409,335,1.480,509
15:50:01,6,250,1.575,000,700,000,700,000,562,500,1.414,851,1.485,777
15:50:06,6,250,1.575,000,700,000,700,000,562,500,1.420,350,1.491,026

简短回顾：我需要将不同的内容记录到不同的文件中。

谁能帮我解决这个问题？

【解决方案1】：

尝试替换这个

<root>
    <level value="ALL" />
    <appender-ref ref="ApplicationLog" />
    <appender-ref ref="DigitalWriteLog" />
    <appender-ref ref="AnalogWriteLog" />
    <appender-ref ref="AnalogReadLog" />
</root>

与：

<root>
    <level value="ALL" />
    <appender-ref ref="ApplicationLog" />
</root>
<logger additivity="false" name="DigitalWriteLog">
  <level value="ALL"/>
  <appender-ref ref="DigitalWriteLog" />
</logger>
<logger additivity="false" name="AnalogWriteLog">
  <level value="DEBUG"/>
  <appender-ref ref="AnalogWriteLog" />
</logger>
<logger additivity="false" name="AnalogReadLog">
  <level value="DEBUG"/>
  <appender-ref ref="AnalogReadLog" />
</logger>
