Log4Net的使用

1)、添加对log4net.dll的引用

 

 

 2）、在配置文件中，对log4net进行配置

"1.0" encoding="utf-8" ?>


  
    
"log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net"/>
  

  
    
    
    "RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
      
      "test.txt"/>
      
      "true"/>
      
      "10"/>
      
      "1024KB"/>
      
      
      "Size"/>
      
      "true"/>
      
      "log4net.Layout.PatternLayout">
        
        "%date [%thread] %-5level %logger - %message%newline"/>
      
    
    
      
      "DEBUG"/>
      ref ref="RollingLogFileAppender"/>
    
  
  
     
        "v4.0" sku=".NETFramework,Version=v4.5.1" />

MVC中：

    
    
"log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net" />
  


  
    
      "ERROR" />
      
      ref ref="SysAppender" />
    
    "WebLogger">
      "DEBUG" />
    

    "SysAppender" type="log4net.Appender.RollingFileAppender,log4net">
      
      "File" value="App_Data/" />
      
      "AppendToFile" value="true" />
      
      "RollingStyle" value="Date" />
      
      "DatePattern" value=""Logs_"yyyyMMdd".txt"" />
      
      "StaticLogFileName" value="false" />
      
      "log4net.Layout.PatternLayout,log4net">
        
        "ConversionPattern" value="%d [%t] %-5p %c - %m%n" />
        
        "Header" value="
---------header-------
" />
        
        "Footer" value="
---------fotter-------
" />
      
    

    "consoleApp" type="log4net.Appender.ConsoleAppender,log4net">
      "log4net.Layout.PatternLayout,log4net">
        "ConversionPattern" value="%d [%t] %-5p %c - %m%n" />

 3）、从配置文件中读取log4net的配置，然后进行初始化

log4net.Config.XmlConfigurator.Configure();

4）、获取日志记录器

ILog logWriter = LogManager.GetLogger("TestDemo");

5）、写入日志（默认写入在bin目录下）

//创建一个调试级别的消息
logWriter.Debug("ssss调试级别的消息");
//创建一个错误级别的消息
logWriter.Error("ssss错误级别的消息");
