如何枚举进程的句柄？

Question

有没有办法如何枚举Windows中给定PID的进程,并获取所有打开的句柄列表(锁定文件等)？

编辑:我不关心语言.如果它在.NET中,我会很高兴,如果在WinApi(C)中,它不会受到伤害.如果在别的东西,我想我可以重写它:-)

我做了一个深谷搜索,发现了这篇文章.本文提供了下载源代码的链接:

我尝试了NtSystemInfoTest.cpp(下载的源代码)中的方法,它工作得非常好.

void ListHandles( DWORD processID, LPCTSTR lpFilter )

该代码具有以下声明:

我希望这可以帮助你.

如果你只是想要一个工具,Sysinternals 的命令行' Handle '工具会这样做.但是,如果您正在寻找代码解决方案,这对您没有帮助.

Answer 3

这是使用ZwQueryProcessInformationDDK的示例。DDK 现在称为“WDK”，可在 MSDN 中使用。如果您没有 MSDN，显然，您也可以从这里获取。

我没有试过，我只是在谷歌上搜索了你的问题。
