Log4Net 入门示例

在网上看了几个教程，都有一些小问题，几经测试，试验了一下，写一个最简单的能用的出来，希望对初学者能有用！

首先在App.Config里面添加：

 

代码

   
     

    
      
    
      <
    
      configSections
    
      >
    
      
 
    
      <
    
      section 
    
      name
    
      ="log4net"
    
      
 type
    
      ="log4net.Config.Log4NetConfigurationSectionHandler,log4net-net-1.0"
    
      />
    
      
 
    
      </
    
      configSections
    
      >
    
      
 
    
      <
    
      log4net
    
      >
    
      
 
    
      <
    
      root
    
      >
    
      
 
    
      <
    
      level 
    
      value
    
      ="WARN"
    
       
    
      />
    
      
 
    
      <
    
      appender-ref 
    
      ref
    
      ="LogFileAppender"
    
       
    
      />
    
      
 
    
      <
    
      appender-ref 
    
      ref
    
      ="ConsoleAppender"
    
       
    
      />
    
      
 
    
      </
    
      root
    
      >
    
      
 
    
      <
    
      appender 
    
      name
    
      ="LogFileAppender"
    
       type
    
      ="log4net.Appender.FileAppender"
    
      >
    
      
 
    
      <
    
      file 
    
      value
    
      ="log-file.txt"
    
       
    
      />
    
      
 
    
      <
    
      appendToFile 
    
      value
    
      ="true"
    
       
    
      />
    
      
 
    
      <
    
      layout 
    
      type
    
      ="log4net.Layout.PatternLayout"
    
      >
    
      
 
    
      <
    
      header 
    
      value
    
      ="[Header]&#13;&#10;"
    
       
    
      />
    
      
 
    
      <
    
      footer 
    
      value
    
      ="[Footer]&#13;&#10;"
    
       
    
      />
    
      
 
    
      <
    
      conversionPattern 
    
      value
    
      ="%date ---[%thread] %-5level '%logger': %message%newline"
    
       
    
      />
    
      
 
    
      </
    
      layout
    
      >
    
      
 
    
      </
    
      appender
    
      >
    
       
 
    
      <
    
      appender 
    
      name
    
      ="ConsoleAppender"
    
       type
    
      ="log4net.Appender.ConsoleAppender"
    
       
    
      >
    
      
 
    
      <
    
      layout 
    
      type
    
      ="log4net.Layout.PatternLayout"
    
      >
    
      
 
    
      <
    
      param 
    
      name
    
      ="ConversionPattern"
    
      
 value
    
      ="%d [%t] %-5p (%c) - %m%n"
    
      
 
    
      />
    
      
 
    
      </
    
      layout
    
      >
    
      
 
    
      </
    
      appender
    
      >
    
      
 
    
      </
    
      log4net
    
      >
   
     

然后在AssemblyInfo.cs添加下面一行。

[assembly: log4net.Config.XmlConfigurator()]

最后就是在代码里使用了。

代码

   
     

    
      
    
      public
    
       
    
      class
    
       WorkerThreadExample
{
 
    
      private
    
       
    
      static
    
       
    
      readonly
    
       log4net.ILog log 
    
      =
    
       log4net.LogManager.GetLogger(
    
      "
    
      test
    
      "
    
      );

 
    
      static
    
       
    
      void
    
       Main()
 {
 
    
      if
    
       (log.IsInfoEnabled) log.Fatal(
    
      "
    
      Application [ConsoleApp] Start
    
      "
    
      );
 log.Info(
    
      "
    
      error
    
      "
    
      );
 log.Fatal(
    
      "
    
      wadsadasd
    
      "
    
      );
 
 }

}
   
     

 

更详细的信息参见文档和  某位博友的文章,不过这篇文章的config好像有一些问题，主要是param的设置上和文档中不一致。
