Log4net 怎么试都不行，help me

[joedong]

使用Log4net 将记录写到文件中却怎么试都不行，帮忙看看


web.config 中配置如下
================================================================
<configSections>
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net" />
</configSections>

......

<log4net>
<!-- Define some output appenders -->
<appender name="LogFileAppender" type="log4net.Appender.FileAppender">
<param name="File" value="Visits-log.txt" />
<param name="AppendToFile" value="true" />
<layout type="log4net.Layout.PatternLayout">
<param name="ConversionPattern" value="%d [%t] %-5p %c [%x] - %m%n" />
</layout>
</appender>
<!-- Setup the root category, add the appenders and set the default level -->
<root>
<level value="DEBUG" />
<appender-ref ref="LogFileAppender" />
</root>
</log4net>

程序代码实现如下(编译通过，运行也不会错误)
＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝
private static readonly log4net.ILog log = log4net.LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);

......

private void Button1_Click(object sender, System.EventArgs e)
{
log.Warn(DateTime.Now.ToString());
}

多谢，问题解决了 ！ 应该在global.asax.cs 的 application_onstart 中启动log4net相关配置即可。
多谢各位指点

请尝试一下配置文件。
<log4net>
<logger name="YourApplicationName">
<level value="DEBUG" />
<appender-ref ref="RollingFile" />
</logger>
<appender name="RollingFile" type="log4net.Appender.RollingFileAppender">
<file value="Logs/rb_log.log" />
<appendToFile value="true" />
<rollingMode value="Date" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%d %-4r [%t] %-5p %c %x - %m%n" />
</layout>
</appender>
</log4net>
CS文件如下：
private static readonly ILog log = LogManager.GetLogger("YourApplicationName");
usage:
log.Error("Error!");
有关详细内容请参考log4net的API接口文档以及手册。上面的代码在VS.NET2003上测试通过。

检查有没有对文件夹的write权限。

Q:Why can't I log to a FileAppender from a web application?
A:The web application runs as a special user account on the web server called ASPNET. This account has restricted permissions to protect the web server from attacks. By default this account may not have permission to write to the file system. Make sure that the ASPNET account has permission to create and write to files in the directory chosen for logging.
