如何检测文件是否被访问（打开） [英] How to detect if a file is accessed (Opened)
问题描述
嗨！
我想创建一个在访问文件时打开的事件（打开）。
我想要什么要做的是监视目录和子目录，如果文件是打开的话。
我试图使用FileSystemWatcher。但它并没有像我预期的那样工作。
我无法在访问文件时触发事件。
任何提示？想法，链接？
问候
马丁

它可以完成（至少在Windows中） - 查看工具FileMon来自
www.sysinternals.com 的示例。我怀疑你需要互操作
到Windows API。抱歉，我不能指出你需要哪个API电话
需要。

It can be done (in Windows at least) - check out the tool FileMon from
www.sysinternals.com for an example. I suspect you will need interop
to the Windows API. Sorry I can''t point you to which API call you will
need.

您是否尝试过NotifyFilters.LastAccess？
如果还不够好为了你，那么你将不得不p / invoke一些win api
（这应该不是很好）

Hi,
Did you try NotifyFilters.LastAccess ?
If not good enough for you , then you will have to p/invoke some win api
(which should not be nice)

嗨！
是的，但是当我打开文件时没有触发任何事件。
我做错了吗？
