c# - log4net 不记录调试语句

Question

我是第一次使用 log4net 并使用提供的配置示例遵循文档，但是调试语句不记录。

信息、错误、警告和致命级别都正确记录。谁能告诉我我错过了什么？

应用程序配置:

<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />

<log4net>
    <appender name="Console" type="log4net.Appender.ColoredConsoleAppender">

        <mapping>
            <level value="INFO" />
            <foreColor value="Green"/>
        </mapping>

        <mapping>
            <level value="DEBUG" />
            <foreColor value="Cyan,HighIntensity"/>
        </mapping>

        <mapping>
            <level value="WARN" />
            <foreColor value="Purple,HighIntensity"/>
        </mapping>

        <mapping>
            <level value="ERROR" />
            <foreColor value="Red,HighIntensity"/>
        </mapping>

        <mapping>
            <level value="FATAL" />
            <foreColor value="Yellow,HighIntensity"/>
        </mapping>

        <layout type="log4net.Layout.PatternLayout">
            <!-- Pattern to output the caller's file name and line number -->
            <conversionPattern value="%5level [%thread] (%file:%line) - %message%newline" />
        </layout>            
    </appender>

    <appender name="RollingFile" type="log4net.Appender.RollingFileAppender">
        <file value="example.log" />
        <appendToFile value="true" />
        <maximumFileSize value="100KB" />
        <maxSizeRollBackups value="2" />

        <layout type="log4net.Layout.PatternLayout">
            <conversionPattern value="%level %thread %logger - %message%newline" />
        </layout>
    </appender>

    <root>
        <level value="INFO" />
        <appender-ref ref="Console" />
        <appender-ref ref="RollingFile" />
    </root>
</log4net>

有些人提到检查 AssemblyInfo for [assembly: log4net.Config.XmlConfigurator()]，但是有或没有这一行没有区别。

记录器声明如下:

private static readonly ILog log = LogManager.GetLogger( typeof( CWD_Netsuite ) );

访问方式如下:

XmlConfigurator.Configure();
log.Debug("Debugging");             //does not get logged
log.Info( "Entering Application" ); //logged to console and log file
log.Debug( "Debug Statement" );     //does not get logged 

log.Error( "Error statement" );     //logged to console and log file
log.Warn( "Warning statement" );    //logged to console and log file
log.Fatal( "Fatal Statement" );     //logged to console and log file

您在根类别中将过滤器设置为 INFO 级别(从而过滤掉所有 DEBUG 级别的消息):

<root>
    <level value="INFO" />
    <appender-ref ref="Console" />
    <appender-ref ref="RollingFile" />
</root>

改成

    <level value="DEBUG" />
