Custom event details:
在这一点上，我想要访问的是“ C：\ inetpub \ wwwroot \ MyAspMvcApp \ bin \ AppConfig.config”文件，以便以具体的方式读取将要在其中订购的文件夹路径放置。
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，仅几次。
我已将C：\ inetpub \ wwwroot \ MyAspMvcApp \上的全部权限授予我的应用程序池标识MyDomain \ MyCustomIdentity，并且还授予了IIS_IUSRS的读取和执行，显示文件夹内容和读取权限。注意：尚未授予IUSR用户访问此文件夹的权限。
任何想法为何会发生这种情况？
