第一步：添加app.log4net配置文件

<?

xml version="1.0" encoding="utf-8"

?>

<

configuration

>

　

<

configSections

>

<

section

name

="log4net"

type

="log4net.Config.Log4NetConfigurationSectionHandler, log4net"

/>

</

configSections

>

<

log4net

>

<

root

>

<

level

value

="ALL"

/>

<

appender-ref

ref

="rollingFile"

/>

</

root

>

<

appender

name

="rollingFile"

type

="log4net.Appender.RollingFileAppender,log4net"

>

<

param

name

="File"

value

="log\\log.txt"

/>

<

param

name

="AppendToFile"

value

="false"

/>

<

param

name

="RollingStyle"

value

="Date"

/>

<

param

name

="DatePattern"

value

="yyyy.MM.dd"

/>

<

param

name

="StaticLogFileName"

value

="true"

/>

<

layout

type

="log4net.Layout.PatternLayout,log4net"

>

<

param

name

="ConversionPattern"

value

="%d [%t] %-5p %c - %m%n"

/>

<

param

name

="Header"

value

="&#13;&#10;----------------------header--------------------------&#13;&#10;"

/>

<

param

name

="Footer"

value

="&#13;&#10;----------------------footer--------------------------&#13;&#10;"

/>

</

layout

>

</

appender

>

</

log4net

>

</

configuration

第二步：启用配置文件，在AssemblyInfo.cs文件里面添加配置

[

assembly:

log4net.Config.XmlConfigurator(ConfigFile =

"

ba.log4net

"

, Watch = true)]

第三步：使用Log4net记录日志

1、获取日志对象

private

static

readonly

log4net.ILog log

=

log4net.LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);

2、写日志

log.Info(

"

生成成功

"

);
