1、添加log4net dll 2、在文件AssemblyInfo.cs加入一句代码,AssemblyInfo.cs的路径所在Properties目录下添加代码如下：// 日志组件配置 [assembly: log4net.Config.DOMConfigurator(ConfigFile = “log4net.config”, Watch = true)] 3、//代码中调用<P></P>//private static readonly log4net.ILog log = log4net.LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod ().DeclaringType);<P> log4net.ILog log= log4net.LogManager.GetLogger(this.GetType());</P><P> logger.Debug(“调试”); logger.Error(“这是一个错误日志”); logger.Fatal(“这是一个致命的错误日志”); logger.Warn(“这是一条警告日志”); logger.Info(“这是一条普通信息”); 4、配置文件</P><P><?xml version=”1.0″ encoding=”utf-8″ ?> <log4net> <appender type=”log4net.Appender.RollingFileAppender,log4net”> <param value=”Logs/Log.log” /> <param value=”true” /> <param value=”10″ /> <param value=”10MB” /> <param value=”Size” /> <param value=”true” /> <param value=”yyyy-MM-dd HH:mm” /> <layout type=”log4net.Layout.PatternLayout”> <param value=”%d [%t] %-5p %c [%x] – %m%n” /> </layout> </appender><!– Print only messages of level DEBUG or above in the packages –> <logger> <level value=”DEBUG”/> </logger> <appender type=”log4net.Appender.RollingFileAppender,log4net” > <param value=”logs/” /> <param value=”true” /> <param value=”Date” /> <param value=””Logs_”yyyyMMdd”.txt”” /> <param value=”false” /> <layout type=”log4net.Layout.PatternLayout,log4net”> <param value=”%d [%t] %-5p %c – %m%n” /> <param value=”—-header——” /> <param value=”—-footer——” /> </layout> </appender> <appender type=”log4net.Appender.ConsoleAppender,log4net”> <layout type=”log4net.Layout.PatternLayout,log4net”> <param value=”%d [%t] %-5p %c – %m%n” /> </layout> </appender> </P> <root> <!–<level value=”DEBUG” />–> <priority value=”ERROR” /> <appender-ref ref=”RollingLogFileAppender” /> </root> </log4net>
，学习会使你永远立于不败之地。
