我试图让Log4Net集成在.NET Core应用程序中运行，该应用程序将部署到AppEngine Flexible环境中。我的出发点是documentation中的示例代码。我的代码看起来像这样：
using log4net; // resolve Log4net
using log4net.Config; // resolve XmlConfigurator
using System.IO; // resolve FileInfo
using System.Reflection; // resolve Assembly
namespace Test
{
public class PlayWithStackdriverLog4net
{
public void Write()
{
log4net.Util.LogLog.InternalDebugging = true; // enable Log4net debugging
var xmlConfiguration = XmlConfigurator.Configure(LogManager.GetRepository(typeof(PlayWithStackdriverLog4net).Assembly), new FileInfo("log4net.xml"));
ILog log = LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
log.Info("An exciting log entry!");
}
}
}
不幸的是，最终结果是我在Google云端控制台的“日志记录”窗格中看不到令人兴奋的日志条目！。我做错了什么？
一些评论：
1）文件log4net.xml几乎是documentation中的文件，除了我用自己的ID替换了PROJECT-ID。
2）Log4net调试输出表明它已成功读取log4net.xml：

3）如果我按照使用Google.Cloud.Logging.V2的Stackdriver Logging Client Libraries的示例，那么我可以找到我的“你好世界”＃39;全局资源类型中的文本按预期方式。
