Log4Net使用

Posted 2021-12-01 ywkcode

1.引用Log4Net.dll

 

2.LogHelper类定义

 

 private static readonly ILog _logger = LogManager.GetLogger("LogTrace");

        //private static log4net.ILog _logger = log4net.LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);

 public static void Info(string message)

 {

    _logger.Info(message);

 }

 public static void Debug(string message)

 {

    _logger.Debug(message);

 }

 

3.配置文件内容添加

  <configSections>

    <!--Add Log4Net Section-->

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

  </configSections>

 

  <log4net>

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

      <param name="File" value="D:\App.log" />

      <!--file可以指定具体的路径 eg : d:\\test.log。不指定的话log被生成在项目的bin/Debug 或者 bin/Release目录下 （web的项目 默认生成在根目录下）-->

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

      <rollingStyle value="Size" />

      <maxSizeRollBackups value="10" />

      <maximumFileSize value="10MB" />

      <staticLogFileName value="true" />

      <layout type="log4net.Layout.PatternLayout">  <!--指定log的格式--> 

        <conversionPattern value="%nTime：%date           %Info：%message%newline" />

      </layout>

    </appender>

    <logger name="LogTrace">

      <level value="ALL" />

      <appender-ref ref="LogFileAppender" />

    </logger>

  </log4net>

 

4.AssemblyInfo配置

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