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

<!--<br /> <br /> Code highlighting produced by Actipro CodeHighlighter (freeware)<br /> http://www.CodeHighlighter.com/<br /> <br /> -->[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

<!--<br /> <br /> Code highlighting produced by Actipro CodeHighlighter (freeware)<br /> http://www.CodeHighlighter.com/<br /> <br /> --><?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

<!--<br /> <br /> Code highlighting produced by Actipro CodeHighlighter (freeware)<br /> http://www.CodeHighlighter.com/<br /> <br /> -->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
