WinForm项目引入日志

NUGET安装包log4net

略

Properties/AssemblyInfo.cs尾部添加代码

[assembly: log4net.Config.XmlConfigurator(ConfigFile = "log4net.config", Watch = true)]

 

根目录下添加log4net.config

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
	<configSections>
		<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net" />
	</configSections>
	<log4net>
		<root>
		</root>
		<logger name="Error">
			<level value="ALL" />
			<appender-ref ref="ErrorAppender" />
		</logger>
		<logger name="InfoLog">
			<level value="ALL" />
			<appender-ref ref="InfoAppender" />
		</logger>
		<appender name="ErrorAppender" type="log4net.Appender.RollingFileAppender,log4net" >
			<param name="File" type="" value="Log/Error" />

			<layout type="log4net.Layout.PatternLayout,log4net">
				<param name="ConversionPattern" value="%n[%d] %c %n%m%n%n" />
			</layout>
		</appender>
		<appender name="InfoAppender" type="log4net.Appender.RollingFileAppender,log4net" >
			<param name="File" type="" value="Log/Info" />
			<param name="AppendToFile" value="true" />
			<param name="RollingStyle" value="Date" />
			<param name="DatePattern" value="yyyyMMdd".txt"" />
			<param name="StaticLogFileName" value="false" />

		</appender>
	</log4net>
</configuration>
