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)]
