RollingFileAppender的log4net最低配置？

Question

我试图找到使log4net工作所需的最低设置。以下是我的配置

<log4net>
    <appender name="something" type="log4net.Appender.RollingFileAppender">
    </appender>
    <root>
        <appender-ref ref="something"/>
    </root>
</log4net>

我收到以下错误：

log4net:ERROR XmlHierarchyConfigurator: Could not create Appender [something] of type [log4net.Appender.RollingFileAppender]. Reported error follows. System.NullReferenceException: Object reference not set to an instance of an object. at log4net.Appender.RollingFileAppender.ActivateOptions() at log4net.Repository.Hierarchy.XmlHierarchyConfigurator.ParseAppender(XmlElement appenderElement) log4net:ERROR XmlHierarchyConfigurator: Appender named [something] not found.

我无法找到有关RollingFileAppender所需设置的任何文档。我还应该添加什么？

看起来您需要文件名和布局部分。我得到了以下工作：

   <log4net>
    <appender name="FileAppender" type="log4net.Appender.RollingFileAppender" >
        <param name="File" value="Logs\\MyAppLog.log"/>
        <layout type="log4net.Layout.PatternLayout">
        </layout>
    </appender>
    <root>
        <appender-ref ref="FileAppender"/>
    </root>
  </log4net>
