问题描述

为什么我在洛到事件查看器收到此错误。我looging在事件查看器异常以及滚动平面文件。如果删除了事件查看器部分，然后滚动平面文件完美的作品，但只有当我添加此它给人的例外

解决方案

我有同样的问题，它在我的配置文件中的错误所致。我引用从我categorySources部分，它并没有在我的听众部分存在跟踪侦听器。我删除了类别和映射（我没有反正使用它们），然后它的工作。我想你可以验证您的配置文件中的配置控制台，然后它会告诉你是什么问题。

I am getting this error while loggin into eventviewer. I am looging the exception in event viewer as well as rolling flat file. If i remove the eventviewer section then rolling flat file works perfectly, but only when i add this it gives the exception

解决方案

I had the same problem and it was due to an error in my configuration file. I referenced trace listeners from my categorySources section which did not exist in my listeners section. I removed the categories and the mappings (i did not use them anyway) and then it worked. I guess you can validate your configuration file in the configuration console and then it will tell you what the problem is.
