我在我的EPiServer应用程序中使用Nlog并且它不记录

Question

我正在使用NLog在我的EPiserver应用程序中记录异常。我用这个blog作为参考，我的应用程序不记录任何东西。

我创建了一个NLOG桥附加器类，并且被配置EPiServerLog.config和NLog.config：

NLogBridgeAppender类：

using System; 
using System.Collections.Generic; 
using log4net.Appender; 
using log4net.Config; 
using log4net.Core; 
using NLog; 

namespace Tietgen.Web.Business.Core 
{ 
    public class NLogBridgeAppender : AppenderSkeleton 
    { 
     Dictionary<string, Logger> _loggers = new Dictionary<string, Logger>(); 
     readonly object _lockObject = new object(); 

     public static void Initialize() 
     { 
      BasicConfigurator.Configure(new NLogBridgeAppender()); 
     } 

     protected override void Append(LoggingEvent loggingEvent) 
     { 
      var nLogEvent = ToNLog(loggingEvent); 
      var nLogger = GetLogger(loggingEvent); 
      nLogger.Log(nLogEvent); 
     } 

     Logger GetLogger(LoggingEvent loggingEvent) 
     { 
      Logger nLogger; 
      if (_loggers.TryGetValue(loggingEvent.LoggerName, out nLogger)) 
      { 
       return nLogger; 
      } 

      lock (_lockObject) 
      { 
       if (_loggers.TryGetValue(loggingEvent.LoggerName, out nLogger)) 
       { 
        return nLogger; 
       } 
       nLogger = LogManager.GetLogger(loggingEvent.LoggerName); 
       _loggers = new Dictionary<string, Logger>(_loggers) 
      { 
      { loggingEvent.LoggerName, nLogger } 
      }; 
      } 
      return nLogger; 
     } 

     private static LogLevel ToNLogLevel(Level level) 
     { 
      LogLevel nLevel; 

      if (level == Level.Fatal) nLevel = LogLevel.Fatal; 
      else if (level == Level.Error) nLevel = LogLevel.Error; 
      else if (level == Level.Warn) nLevel = LogLevel.Warn; 
      else if (level == Level.Debug) nLevel = LogLevel.Debug; 
      else if (level == Level.Info) nLevel = LogLevel.Info; 
      else if (level == Level.Trace) nLevel = LogLevel.Trace; 
      else if (level == Level.Off) nLevel = LogLevel.Off; 
      else 
      { 
       var message = string.Format("Unsupported log level: {0}.", level); 
       throw new NotSupportedException(message); 
      } 

      return nLevel; 
     } 

     private static LogEventInfo ToNLog(LoggingEvent loggingEvent) 
     { 
      return new LogEventInfo 
      { 
       Exception = loggingEvent.ExceptionObject, 
       LoggerName = loggingEvent.LoggerName, 
       Message = Convert.ToString(loggingEvent.MessageObject), 
       Level = ToNLogLevel(loggingEvent.Level), 
       TimeStamp = loggingEvent.TimeStamp, 
       FormatProvider = null 
      }; 
     } 
    } 
} 

NLog.config：

<!--

好吧，我结束了在我们的web应用程序单独使用log4net的，以完成这项工作。
