log4net - log4net 没有将日志写入文件

Question

我有以下代码将日志项写入文件。它正确地创建了文件，但文件中没有任何内容（即它的大小始终为 0 字节）。我究竟做错了什么？

           ILog log = LogManager.GetLogger("mainlog");
            RollingFileAppender logAppender = new RollingFileAppender();
            string filePath = ConfigurationManager.AppSettings["LoggingFilePath"];

            filePath = filePath + "EventLog.csv";


            logAppender.File = filePath;
            logAppender.AppendToFile = true;
            logAppender.RollingStyle = RollingFileAppender.RollingMode.Date;
            logAppender.MaxSizeRollBackups = 60;
            logAppender.StaticLogFileName = true;

            log4net.Config.BasicConfigurator.Configure(logAppender);
            logAppender.ActivateOptions();

            StringBuilder sb = new StringBuilder();
            sb.Append(DateTime.Now.ToShortDateString());
            sb.Append(",");
            sb.Append(DateTime.Now.ToShortTimeString());
            sb.Append(",");
            sb.Append(applicationID.ToString());
            sb.Append(",");
            sb.Append(itemName);
            sb.Append(",");
            sb.Append(itemException.Message);
            sb.Append(",");
            sb.Append(itemException.StackTrace);
            sb.Append(",");
            sb.Append(itemException.Source);
            sb.Append(",");
            sb.Append(itemException.TargetSite);
            sb.Append(",");
            sb.Append(itemEventType.ToString());

            log.Debug(sb.ToString());

            logAppender.Close();

您需要指定布局，例如

 logAppender.Layout = new log4net.Layout.PatternLayout(
     "%date [%thread] %-5level %logger [%property{NDC}] - %message%newline");
