asp.net-mvc - 访问自定义 asp.net 应用程序配置文件时出现 DirectoryNotFoundException

Question

我有一个 ASP.NET MVC 应用程序，有时会在应用程序类别下的 Windows 事件日志中抛出以下消息错误（敏感数据已被其他字符串替换）：

Custom event details: 

此时我要做的是访问“C:\inetpub\wwwroot\MyAspMvcApp\bin\AppConfig.config”文件以读取标签，具体来说，就是放置订单的文件夹路径。

AppConfig.config 是一个简单的 XML 文件。此外，路径“C:\inetpub\wwwroot\MyAspMvcApp\bin”和配置文件 AppConfig.config 始终存在。

此错误并非总是发生，只会发生几次。

我已将 C:\inetpub\wwwroot\MyAspMvcApp\ 的完整权限授予我的应用程序池标识 MyDomain\MyCustomIdentity，并且我已授予 IIS_IUSRS 读取和执行、显示文件夹内容和读取权限。注意：未授予 IUSR 用户访问此文件夹的权限。

任何想法为什么会发生这种情况？
