Winform Log4net 配置写不同文件

以下配置了二种写文件，第一种根据日期写文件yyyyMMdd.txt，第二种是写固定文件login.txt。

1， 下载Log4net组件：

http://logging.apache.org/log4net/download.html

2，将log4net.dll加到项目引用中；
 
3，在app.config中添加相关配置信息，文件内容如下：

   <?xml version="1.0"?>
<configuration>
  <configSections>
    <sectionGroup name="applicationSettings" type="System.Configuration.ApplicationSettingsGroup, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089">
      <section name="ChinaBank.Properties.Settings" type="System.Configuration.ClientSettingsSection, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false"/>
    </sectionGroup>
    <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net-net-1.0"/>
  </configSections>
  <log4net>
    <logger name="Daily.Logging">
      <level value="INFO"/>
      <appender-ref ref="DailyAppender" />
    </logger>
    <logger name="Login.Logging">
      <level value="INFO"/>
      <appender-ref ref="LoginAppender" />
    </logger>
    <appender name="DailyAppender" type="log4net.Appender.RollingFileAppender,log4net" >
      <param name="File" value="Logs/" />
      <param name="AppendToFile" value="true" />
      <param name="RollingStyle" value="Date" />
      <param name="DatePattern" value="yyyyMMdd.'txt'" />
      <param name="StaticLogFileName" value="false" />
      <layout type="log4net.Layout.PatternLayout,log4net">
        <param name="ConversionPattern" value="%m%n" />
      </layout>
    </appender>
    <appender name="LoginAppender" type="log4net.Appender.RollingFileAppender,log4net" >
      <param name="File" value="Logs/login.txt" />
      <param name="AppendToFile" value="true" />
      <layout type="log4net.Layout.PatternLayout,log4net">
        <param name="ConversionPattern" value="%d|%m|%n" />
      </layout>
    </appender>
  </log4net>
<!--这里为appSettings等其它节点信息-->
</configuration>
 
 
4，在AssemblyInfo.cs最下面添加(其中XXXXX.exe.config为app.config在binDebug中生成的文件名，以实际为准)：
[assembly: log4net.Config.XmlConfigurator(ConfigFile = "./XXXXX.exe.config", ConfigFileExtension = "config", Watch = true)]
 

5，在项目中使用Log4net：

//根据日期写文件yyyyMMdd.txt
log4net.ILog log = log4net.LogManager.GetLogger("Daily.Logging");  
log.Info("这是一条普通信息");    

//写固定文件login.txt
log4net.ILog log2 = log4net.LogManager.GetLogger("Login.Logging");
log2.Info("用户张三登录");
