LOG4NET用法

log 4net组件下载:log4net.dll

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&quot;.htm&quot;" /><param name="RollingStyle" value="Date" /><layout type="log4net.Layout.PatternLayout"><param name="ConversionPattern" value="&lt;HR COLOR=red&gt;%n异常时间：%d [%t] &lt;BR&gt;%n异常级别：%-5p &lt;BR&gt;%n异 常 类：%c [%x] &lt;BR&gt;%n%m &lt;BR&gt;%n &lt;HR Size=1&gt;" /></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&quot;.htm&quot;" /><param name="RollingStyle" value="Date" /><layout type="log4net.Layout.PatternLayout"><param name="ConversionPattern" value="&lt;HR COLOR=blue&gt;%n日志时间：%d [%t] &lt;BR&gt;%n日志级别：%-5p &lt;BR&gt;%n日 志 类：%c [%x] &lt;BR&gt;%n%m &lt;BR&gt;%n &lt;HR Size=1&gt;" /></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);
   }
