如何通过ASP.NET MVC访问Program Files文件夹
[英]How to access Program Files folder via ASP.NET MVC
问题描述
我们必须从ASP.NET MVC应用程序访问Program Files夹（用于读/写操作）。
你可以猜到； Windows不允许这样做。 我尝试按照.NET错误日志中的建议，使用用户ASPNET （ASP.NET计算机帐户）手动授予对文件夹和文件的完全控制访问权限，但是它不起作用。
- IIS：版本8.5.9600.16384 @ Windows 8.1 x64
- 流水线模式：集成
- 应用程序池：自定义（我们的自定义应用程序池）
**这是.Net错误日志：**
