我正在尝试使用企业库将异常记录到数据库中。我有应用程序设置以在连接到数据库时使用模拟，但是当它尝试记录任何内容时它似乎不起作用（其余时间工作正常）。

日志记录块是否忽略模拟或我错过了什么？跟踪数据库时，它显示机器名称正在尝试连接到数据库的错误，而不是我用来模拟的服务帐户。

以下是一些配置：

<identity impersonate="true" userName="name" password="pwd"/>

更新： 我在 loggingConfiguration 部分添加了 revertImpersonation="false" 属性，但它似乎没有任何效果。

更新 2： 如果其他人遇到同样的问题，这不是 EnterpriseLibrary 问题。它与页面生命周期和模拟有关。在生命周期的这一点（应用程序错误块）中，尚未发生模拟，因此无法连接到数据库进行日志记录。对于这一部分，我改为在代码中手动启动模拟来解决这个问题。
