sharepoint下的log4net，错过了神奇之处

我花了一上午的时间研究了一整套可能的问题，即为什么在SharePoint 2010下安装时log4net没有写入文件

我尝试了单独的log4net文件路由，但目前正在web.config中配置它

我已经在web.config中将trust更新为medium，log4net dll也在GAC中。当我设置断点时，我的记录器在启用所有日志记录的情况下看起来很好，但是.Info（）通过时没有错误，但是日志文件没有创建

幸运的是，我给了每个人&asp.net应用程序池运行方式用户对根日志文件夹的完全控制权。以下是配置代码段和应用程序启动代码：

<configuration>
  <configSections>
    <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net, Version=1.2.10.0, Culture=neutral, PublicKeyToken=1b44e1d426115821" />
    ...

    <log4net>
<appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
  <file value="c:\temp\log.txt" />
  <appendToFile value="true" />
  <rollingStyle value="Size" />
  <maxSizeRollBackups value="10" />
  <maximumFileSize value="5MB" />
  <staticLogFileName value="true" />
  <layout type="log4net.Layout.PatternLayout">
    <conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}] - %message%newline" />
  </layout>
</appender>
  </log4net>




    private static ILog logger; 

    protected void Application_Start(object sender, EventArgs e)
    {
      ////This tells log4net where to go and look for its configuration file and also to watch it for any changes
      //log4net.Config.XmlConfigurator.ConfigureAndWatch(new System.IO.FileInfo(@"C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\Config\Moogle\Log4Net.config"));

      SPSecurity.RunWithElevatedPrivileges(delegate
        {
          log4net.Config.XmlConfigurator.Configure();

          logger = LogManager.GetLogger("Moogle.Web");
          logger.Info("Application_Start Fired");
        });
    }

有什么想法吗？

我知道log4net很棒，而且在SP2010环境下速度更快。我强烈建议将自定义错误消息写入ULS（现在SP2010中也有DB选项）

好样本

在做了一些挖掘之后，我发现了log4net的一个有用特性，可以让它自己进行诊断

您可以添加以下应用程序设置：

<add key="log4net.Internal.Debug" value="true"/>

我一直认为这是许可证。。。那么这个配置是怎么回事

编辑-工作配置

这里有一个独立的log4net.config，它确实有效（在剪切和粘贴的地方要小心！）

<add key="log4net.Internal.Debug" value="true"/>

<configuration>
    ...

    <system.diagnostics>
        <trace autoflush="true">
            <listeners>
                <add 
                    name="textWriterTraceListener" 
                    type="System.Diagnostics.TextWriterTraceListener" 
                    initializeData="C:\tmp\log4net.txt" />
            </listeners>
        </trace>
    </system.diagnostics>

    ...
</configuration>
