Log4Net使用

1、自定义配置

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
	<log4net>
		<appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
			<datePattern value="yyyyMMdd\\yyyy-MM-dd'log.txt'" />
			<encoding value="utf-8" />
			<file value="..\\..\\logs\\" />
			<appendToFile value="true" />
			<rollingStyle value="Date" />
			<staticLogFileName value="false" />
			<param name="MaxSizeRollBackups" value="100" />
			<layout type="log4net.Layout.PatternLayout">
				<conversionPattern value="%newline %nDatetime：%utcdate %nHostName:%property{log4net:HostName} %nThreadID:[%thread] %nLogLevel：  %-5level %nClassName：%logger property: [%property{NDC}] - %nDescription：%message%newline %n" />
			</layout>
		</appender>
		<root>
			<level value="All" />
			<appender-ref ref="RollingLogFileAppender" />
		</root>
	</log4net>
</configuration>

2、使用

 public class MainWindowViewModel : BindableBase
 {

     private readonly ILog logger=LogManager.GetLogger(typeof(MainWindowViewModel));
     public MainWindowViewModel()
     {
         logger.Debug("this is a Debug");
     }
 }
