谢谢,祝你圣诞快乐!我已经实现了这一点,添加一个SafeHandle类,我的进程安全描述符可以被修改,但它似乎没有做我想做的事情。我试图否认程序正确终止。我在添加拒绝规则之前和之后得到安全描述符,它看起来应该可以工作,但我仍然可以终止程序。我是否需要在进程安全描述符上设置访问控制? – 2009-12-16 19:35:54
这可能与您是所有者这一事实有关 - 可能存在一些未公开的特殊情况,用于处理ACL的自动特权扩展。拒绝ACE *应该总是优先于允许。也许尝试改变主人看看是否有任何影响。 – nitzmahone 2009-12-16 20:54:45
对不起,是的 - 您需要添加对受保护的Persist方法的调用,才能将ACL写入进程。我没有仔细查看NativeObjectSecurity。我添加了一个“SaveChanges”方法,将进程句柄传递给Persist,并且这样做了。 – nitzmahone 2009-12-16 21:14:35
