如何在.NET库类中记录应用程序洞察？

using log4net;

namespace YourNamespace
{
    public class YourClass
    {
        private static readonly ILog log = LogManager.GetLogger(typeof(YourClass));

        public YourClass()
        {
            log4net.Config.XmlConfigurator.Configure(); // 初始化log4net配置
        }

        public void YourMethod()
        {
            // 记录日志
            log.Debug("Debug message");
            log.Info("Info message");
            log.Warn("Warning message");
            log.Error("Error message");
            log.Fatal("Fatal message");
        }
    }
}

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