So my quetion is how to make the CD unusable so that it is not used by anyone after its first use. I have to do it using .Net 3.5

推荐答案

将任何内容写入C:root也是非常不友好的. 15年前，这已经不是一个好主意.

Writing anything into C: root is pretty unfriendly too. That was already not a good idea 15 years ago.

您的计划"存在几个问题.

0)并非每个人都为可移动媒体打开了自动运行功能(例如，我没有).

1)您不能禁用"特定的CD.根本不可能做到.

2)您唯一的办法是让应用程序在运行时注册其媒体.这可以通过以下几种方式之一完成-用户的本地注册表(可以由用户手动发现和删除)，用户的应用程序数据文件夹(可以由用户手动删除)或远程注册表数据库(这实际上会锁定应用程序本身，使其无法使用.

如果应用程序也不能从CD上运行，也可以使它拒绝运行.

There are several issues with your "plan".

0) Not everyone has auto-run turned on for removable media (for instance, I don''t).

1) You can''t "disable" a particular CD. It''s simply impossible to do.

2) Your only recourse is to have the application register its media when it''s run. This can be accomplished one of several ways - the user''s local registry (can be discovered and removed manually by the user), the user''s application data folder (can be removed manually by the user), or a remote registry database (this would actually lock out the app itself from being used.

You could make the app refuse to run if it''s not running from a CD, as well.

您可以保存信息，表明该光盘已经在计算机上变红并拒绝.再次执行此操作，但这不会阻止人们将同一张光盘与另一台计算机一起使用.

我认为您不能真正阻止CD(即销毁光盘上的数据)，至少不能用cd-r，阻止，但是为什么不使用cd-rw并在首次使用后擦除数据呢? 好的，不好的主意，请参见答案下方的约翰·西蒙斯(John Simmons)的评论.

You could save information, that this disc hase been red already on the computer and refuse to do it a second time, but that won''t stop people from using the same disc with another computer.

I don''t think you can really block the cd (i.e. destroy the data on the disc), at least not with a cd-r, but why not use cd-rw and erase the data after its first use? edit: Ok, bad idea, see John Simmons'' comment below the answers.
