ASP.Net2.0使用Log4Net(二)

（二）使用单独的配置文件，不放在web.config里
 1.新建一website.
 2.添加一个类库工程，取名LogNet
 
3. 为LogNet工程引用log4net.dll
4. 双击打开AssemblyInfo.cs在最后添加

<!----> [assembly: log4net.Config.XmlConfigurator(ConfigFile  =   " log4net.config " , Watch  =   true )]

5. 为LogNet工程添加一个logBLL.cs文件，我们把日志调用封装到这一层

using  System;
using  System.Collections.Generic;
using  System.Text;
namespace  LogNet
{
    public class LogBLL
    {
        public static void debug(string message)
        {
            log4net.ILog log = log4net.LogManager.GetLogger("Test");
            if (log.IsDebugEnabled)
            {
                log.Debug(message);
            }
            log = null;
        }
        public static void error(string message)
        {
            log4net.ILog log = log4net.LogManager.GetLogger("Test");
            if (log.IsErrorEnabled)
            {
                log.Error(message);
            }
            log = null;
        }
        public static void fatal(string message)
        {

            log4net.ILog log = log4net.LogManager.GetLogger("Test");
            if (log.IsFatalEnabled)
            {
                log.Fatal(message);
            }
            log = null;
        }
        public static void info(string message)
        {
            log4net.ILog log = log4net.LogManager.GetLogger("Test");
            if (log.IsInfoEnabled)
            {
                log.Info(message);
            }
            log = null;
        }

        public static void warn(string message)
        {
            log4net.ILog log = log4net.LogManager.GetLogger("Test");
            if (log.IsWarnEnabled)
            {
                log.Warn(message);
            }
            log = null;
        }
    }
}

6.在web站点根目录下添加一个log4net.config文件，内容如下

<!----> <? xml version="1.0" encoding="utf-8"  ?>
< configuration >
     < configSections >
         < section  name ="log4net"   type ="log4net.Config.Log4NetConfigurationSectionHandler,log4net"   />
     </ configSections >
     < log4net >
         < root >
             <!--
            <level value="ALL" />
            <appender-ref ref="rootFile" />
             -->
         </ root >
         < logger  name ="Test" >
             < level  value ="DEBUG"   />
             < appender-ref  ref ="rollingFile"   />
         </ logger >
         < appender   name ="rollingFile"  type ="log4net.Appender.RollingFileAppender,log4net"   >
             < param  name ="File"  type =""   value ="log/"   />
             < param  name ="AppendToFile"  value ="true"   />
             < param  name ="RollingStyle"  value ="Date"   />
             < param  name ="DatePattern"  value ="yyyyMMdd"   />
             < param  name ="StaticLogFileName"  value ="false"   />
             < layout  type ="log4net.Layout.PatternLayout,log4net" >                
                 < param  name ="ConversionPattern"  value ="%d [%t] %-5p %c - %m%n"   />
                 < param  name ="Header"  value =" ----------------------header-------------- "   />
                 < param  name ="Footer"  value =" ----------------------footer-------------- "   />         
             </ layout >
         </ appender >         
     </ log4net >
</ configuration >

7.编译LogNet工程
8.为web引入LogNet工程bin目录下的LogNet.dll
9.在default.aspx.cs里写入如下代码

<!----> using  System;
using  System.Configuration;
using  System.Data;
using  System.Web;
using  System.Web.Security;
using  System.Web.UI;
using  System.Web.UI.HtmlControls;
using  System.Web.UI.WebControls;
using  System.Web.UI.WebControls.WebParts;
using  LogNet;  // 引用程序集
public  partial  class  _Default : System.Web.UI.Page 
{
     protected   void  Page_Load( object  sender, EventArgs e)
    {
         if  ( ! Page.IsPostBack)
        {
            LogBLL.debug( " 测试信息 " );          
        }
    }
}

10.运行，将在web目录下的log目录下看到日志文件
  ----------------------header--------------------------
2007-11-24 12:16:24,171 [4] DEBUG LiveBookings - 测试信息
2007-11-24 12:16:46,312 [4] DEBUG LiveBookings - 测试信息
----------------------footer--------------------------
