C# 与发布模式相比，log4net在调试模式下使用不同的xml配置文件

我有一个webapp，在调试模式下运行时，与在发布模式下运行时相比，我希望使用不同的log4net配置文件

我使用的是log4net版本2.0.3

在我的AssemblyInfo.cs类中，我有以下代码：

#if DEBUG
[assembly: log4net.Config.XmlConfigurator(ConfigFile = "log4netDebug.xml",     Watch = true)]
#else
[assembly: log4net.Config.XmlConfigurator(ConfigFile = "log4netLive.xml", Watch = true)]
#endif

log4net.Config.XmlConfigurator.Configure(); 
log = LogManager.GetLogger(typeof(GlobalApp));

信息

我已经测试了这个配置脚本，如果我把它放在web.config文件中，它就会工作。 log4netDebug.xml文件设置了“始终复制”属性

当我尝试这样做时： System.IO.FileInfo fi=new System.IO.FileInfo（“Log4NetDebug.xml”）； log4net.Config.XmlConfigurator.ConfigureAndWatch（fi）

这也不行。
我已经阅读了几个stackoverflow和其他网页，描述了如何做到这一点，我似乎正在做他们建议我做的事情，但它似乎仍然不起作用

你知道为什么吗？

如果你查看这个类，你会发现它需要新文件的完全限定名或相对文件名

因此，当您执行此操作时，

System.IO.FileInfo fi=new System.IO.FileInfo（“Log4NetDebug.xml”）您需要指定文件的完整路径

由于这是在web应用程序中，您可能需要以下内容：

var logFile = new FileInfo(Path.Combine(HttpRuntime.BinDirectory, "Log4NetDebug.xml"));
