如何從Custom appender（Log4net）獲取Layout屬性？

Question

我已經使用Log4net實現了一個CustomAppender。如何從Appender中的patternLayout訪問Layout屬性。

  public class CutomAppender : AppenderSkeleton
{
     protected override void Append(LoggingEvent loggingEvent)
    {
      //My custom code here...........
    }
}

配置文件：

<log4net>
 <appender name="CutomAppender" type="log4netCustomAppender.CutomAppender,log4netCustomAppender">   
  <layout type="log4net.Layout.PatternLayout">
   <conversionPattern value="%date [%thread] %-5level %logger - %message%newline" />
  </layout>
 </appender>
 <root>                                                                               
<level value="ALL" />
<appender-ref ref="CutomAppender" />
 </root>
</log4net>

要獲取布局信息，只需使用基本AppenderSkeleton類的Layout屬性。 要獲取已在此布局中呈現的消息，請使用此相同基類中的RenderLoggingEvent方法：

public class CutomAppender : AppenderSkeleton
{
    protected override void Append(LoggingEvent loggingEvent)
    {
        string renderedMessage = base.RenderLoggingEvent(loggingEvent);
        ILayout layout = base.Layout;
        // do something here
    }
}
