如何配置log4net以便log.IsDebugEnabled为true？ [英] How do I configure log4net so that log.IsDebugEnabled is true?

问题描述

我试图在Visual Studio 2005的ASP.NET应用程序中使用log4net。我已经声明了一个日志记录器的实例，如下所示：

I am trying to use log4net in an ASP.NET application with Visual Studio 2005. I have declared an instance of the logger like so:

Private Shared ReadOnly log As ILog = LogManager.GetLogger("")

尝试以下列方式使用它：

I am trying to use it in the following manner:

If log.IsDebugEnabled Then
   log.Debug("Integration Services Constructed")
End If

这是我的配置：

<log4net>

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

    <appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
        <file value="..\\logs\\logfile.log"/>
        <appendToFile value="true"/>
        <rollingStyle value="Size"/>
        <maxSizeRollBackups value="10"/>
        <maximumFileSize value="1MB"/>
        <staticLogFileName value="true"/>
        <layout type="log4net.Layout.PatternLayout">
            <conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}] - %message%newline"/>
        </layout>
        <filter type="log4net.Filter.LevelRangeFilter">
            <param name="LevelMin" value="DEBUG" />
            <param name="LevelMax" value="FATAL" />
        </filter>
    </appender>

</log4net>

推荐答案

您必须调用log4net.Config.XmlConfigurator.Configure（）;
在ASP.NET应用程序中，您可能希望将此调用放在Application_Start

You have to call log4net.Config.XmlConfigurator.Configure(); In an ASP.NET app you probably want to put this call in Application_Start
