LOG4NET用法(个人比较喜欢的用法)

web.config配置如下：

<?xml version="1.0" encoding="utf-8" ?><configuration> <configSections> <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net" /> </configSections> <log4net> <logger name="logerror"> <level value="ERROR" /> <appender-ref ref="ErrorAppender" /> </logger> <logger name="loginfo"> <level value="INFO" /> <appender-ref ref="InfoAppender" /> </logger> <appender name="ErrorAppender" type="log4net.Appender.RollingFileAppender"> <param name="File" value="Log//LogError//" /> <param name="AppendToFile" value="true" /> <param name="MaxSizeRollBackups" value="100" /> <param name="MaxFileSize" value="10240" /> <param name="StaticLogFileName" value="false" /> <param name="DatePattern" value="yyyyMMdd".htm"" /> <param name="RollingStyle" value="Date" /> <layout type="log4net.Layout.PatternLayout"> <param name="ConversionPattern" value="<HR COLOR=red>%n异常时间：%d [%t] <BR>%n异常级别：%-5p <BR>%n异 常 类：%c [%x] <BR>%n%m <BR>%n <HR Size=1>" /> </layout> </appender> <appender name="InfoAppender" type="log4net.Appender.RollingFileAppender"> <param name="File" value="Log//LogInfo//" /> <param name="AppendToFile" value="true" /> <param name="MaxFileSize" value="10240" /> <param name="MaxSizeRollBackups" value="100" /> <param name="StaticLogFileName" value="false" /> <param name="DatePattern" value="yyyyMMdd".htm"" /> <param name="RollingStyle" value="Date" /> <layout type="log4net.Layout.PatternLayout"> <param name="ConversionPattern" value="<HR COLOR=blue>%n日志时间：%d [%t] <BR>%n日志级别：%-5p <BR>%n日 志 类：%c [%x] <BR>%n%m <BR>%n <HR Size=1>" /> </layout> </appender> </log4net> <system.web> <compilation defaultLanguage="c#" debug="true" /> <customErrors mode="RemoteOnly" /> <authentication mode="Windows" /> <authorization> <allow users="*" /> </authorization> <trace enabled="false" requestLimit="10" pageOutput="false" traceMode="SortByTime" localOnly="true" /> <sessionState mode="InProc" stateConnectionString="tcpip=127.0.0.1:42424" sqlConnectionString="data source=127.0.0.1;Trusted_Connection=yes" cookieless="false" timeout="20" /> <globalization requestEncoding="utf-8" responseEncoding="utf-8" /> </system.web></configuration>

LOG操作类

using System;using System.IO;namespace TankAction.SystemLog{ /**//// <summary> /// LogHelper的摘要说明。 /// </summary> public class LogHelper { private SystemLog() { } public static readonly log4net.ILog loginfo = log4net.LogManager.GetLogger("loginfo"); public static readonly log4net.ILog logerror = log4net.LogManager.GetLogger("logerror"); public static void SetConfig() { log4net.Config.DOMConfigurator.Configure(); } public static void SetConfig(FileInfo configFile) { log4net.Config.DOMConfigurator.Configure(configFile); } public static void WriteLog(string info) { if(loginfo.IsInfoEnabled) { loginfo.Info(info); } } public static void WriteLog(string info,Exception se) { if(logerror.IsErrorEnabled) { logerror.Error(info,se); } } }}

Global.asax.cs文件配置如下：protected void Application_Start(Object sender, EventArgs e) { SystemLog.SetConfig(); } protected void Application_Error(Object sender, EventArgs e) { Exception objExp = HttpContext.Current.Server.GetLastError(); LogHelper.WriteLog("/r/n客户机IP:"+ Request.UserHostAddress +"/r/n错误地址:"+ Request.Url +"/r/n异常信息:"+ Server.GetLastError().Message,objExp); }

eg:
   try
   {}
   catch(Exception ex)
   {
       LogHelper.WriteLog("ErrorInfo"ex);
   }
