Log4net没有记录任何内容

我无法让log4net在我的ASP上工作。NET项目。我的网站。配置如下所示:

<configSections>
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net"/>
 </configSections>
<log4net debug="true">
<appender name="console" type="log4net.Appender.ConsoleAppender">
  <layout type="log4net.Layout.PatternLayout">
    <conversionPattern value="%date %level %logger - %message%newline" />
  </layout>
</appender>
<appender name="file" type="log4net.Appender.RollingFileAppender">
  <file value="CardGame.log" />
  <appendToFile value="true" />
  <rollingStyle value="Size" />
  <maxSizeRollBackups value="5" />
  <maximumFileSize value="10MB" />
  <staticLogFileName value="true" />
  <layout type="log4net.Layout.PatternLayout">
    <conversionPattern value="%date [%thread] %level %logger - %message%newline" />
  </layout>
</appender>
<root>
  <level value="ALL"/>
  <appender-ref ref="console" />
  <appender-ref ref="file" />
</root>
</log4net>

我的LogHelper类如下所示:

public class LogHelper
{
    private static LogHelper _instance = new LogHelper();
    private static volatile object _lock = new object();
    public ILog Logger;

    public static LogHelper Instance
    {
        get
        {
            lock (_lock)
            {
                if (_instance == null)
                {
                    _instance = new LogHelper();
                }
            }
            return _instance;
        }
    }

    private LogHelper()
    {
        Logger = LogManager.GetLogger(typeof(LogHelper));
        Logger.Debug("Debug message");
        Logger.Warn("Warn message");
        Logger.Error("Error message");
        Logger.Fatal("Fatal message");
    }
}

我还添加了一行

log4net.Config.XmlConfigurator.Configure();

要在全局中启动Application\u。尽快。cs公司

然而,构造函数中的日志都不起作用,我对它为什么不起作用的想法也不多了。
