FileIOPermissions-阻止对目录的写访问 [英] FileIOPermissions - Preventing write access to a directory

问题描述

我目前正在研究一个项目，该项目将阻止在将USB闪存驱动器插入计算机时对其进行写访问.我已经研究过使用FileIOPermission类使程序集具有只读访问权限，但是使用该类会阻止其他应用程序写入驱动器吗?
我还从本文 [ ^ ]，但这将阻止对所有USB设备的写访问.

I''m currently working on a project that would prevent write access to a usb flash drive when it''s inserted into a machine. I''ve looked into using the FileIOPermission class to make the assembly have read-only access, but would using that class prevent other applications from writing to the drive?
I''ve also looked at editing the registry from this article[^], but that would prevent write access to all usb devices.

Is there a way to prevent write access to one usb device?

But, it does show techniques for write-protecting all USB drives, not a specific one.
