log4g使用《转》

log4net下载地址:http://logging.apache.org/log4net/download.html
下载 incubating-log4net-1.2.10.zip
在webform开发环境中,log4net的配置必须放在网站根目录下的web.config中,
添加以下配置
<configSections>
    <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net"/>
</configSections>
上边的配置必须紧挨着<configuration>,否则会提示错误
"Error    49    D:\wwwroot\Default.aspx: ASP.NET runtime error: 每个配置文件中只允许存在一个 <configSections> 元素，并且，如果存在该元素，它还必须是根 <configuration> 元素的第一个子元素。 (D:\wwwroot\web.config line 18)    D:\wwwroot\Default.aspx    1    1    D:\wwwroot\
"

然后添加

<log4net>
    <appender name="LogFileAppender" type="log4net.Appender.FileAppender">
      
      <param name="File" value="Logs\\Log4Net.log"/>
      
      <layout type="log4net.Layout.PatternLayout">
        <param name="ConversionPattern" value="%d [%t] %-5p %c %m%n"/>
      </layout>
    </appender>
    <appender name="SmtpAppender" type="log4net.Appender.SmtpAppender">
      <to value="" />
      <from value="" />
      <subject value="" />
      <smtpHost value="" />
      <bufferSize value="512" />
      <lossy value="true" />
      <evaluator type="log4net.Core.LevelEvaluator">
        <threshold value="WARN"/>
      </evaluator>
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%newline%date [%thread] %-5level %logger [%property] - %message%newline%newline%newline" />
      </layout>
    </appender>

    <logger name="File">
      <level value="All" />
      <appender-ref ref="LogFileAppender" />
    </logger>
    <logger name="EmailLog">
      <level value="All" />
      <appender-ref ref="SmtpAppender" />
    </logger>
</log4net>

需要注意的是,多数网上的教程都提到,需要在AssemblyInfo.cs文件中,
[assembly: log4net.Config.XmlConfigurator(ConfigFile = "Web.config", Watch = true)]

按照要求做了可是写不到文件里?怎么回事?
后来在CSDN中找到了答案,大意就是说,VS2005(我使用的VS2008)中,不会生成固定名称的DLL
不保证上行代码总被执行,建议款封装成静态类

按此说法,经实验表明是可取的!~以下为封装好了的Log类,在保证上述要求后,记得添加DLL引用,
然后直接Copy下边的代码就可以了.
