log4net在多层架构中的使用

在底层类库项目中定义一个日志类

public class LogHelper

{

private static log4net.ILog log = log4net.LogManager.GetLogger("MyLogger");

public static void Debug(string content)

{

log.Debug(content);

}

public static void Info(string content)

{

log.Info(content);

}

}

在该类库中引用log4net.dll,并在

assemblyInfo.cs中添加

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

然后再该项目中添加log4net配置文件log4net.config，代码如下：

<?xml version="1.0" encoding="utf-8" ?>

<configuration>

<configSections>

<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net-net-1.0"/>

</configSections>

<log4net>

<root>

<level value="ALL" />

<appender-ref ref="RollingLogFileAppender" />

</root>

<appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">

<param name="File" value="log/log-"/>

<param name="AppendToFile" value="true"/>

<param name="MaxSizeRollBackups" value="10"/>

<param name="StaticLogFileName" value="false"/>

<param name="DatePattern" value="yyyy-MM-dd".log""/>

<param name="RollingStyle" value="Date"/>

<layout type="log4net.Layout.PatternLayout">

<param name="ConversionPattern" value="%d [%t] %-5p %c [%x] - %m%n%n"/>

</layout>

</appender>

</log4net>

<startup>

<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/>

</startup>

</configuration>

上层模块中可以直接调用
