推荐答案

您可以使用<一个href="http://msdn.microsoft.com/en-us/library/system.io.filesystemwatcher.aspx"><$c$c>FileSystemWatcher - 但是，这并不让你截获该事件，做事前手 - 它只是告诉你一个事实，即一个特定的文件或目录已影响到以某种方式后

You can use FileSystemWatcher - but this doesn't let you intercept the event and do things before hand - it only informs you after the fact that a particular file or directory has been affected in some way.

截取文件访问是不是你可以很容易做到。

Intercepting file access is not something you can do easily.

您可以编写一个文件系统过滤驱动，这是一个非托管的DLL文件，将O / S将加载，可以对文件或文件夹 拦截行动。然而，这不是一个简单的任务。

You can write a file system filter driver, which is an unmanaged DLL which the O/S will load that can intercept operations on files or folders. However, this isn't a trivial task.

什么是你想达到的，也许还有一个更简单的方法吗？

What are you trying to achieve, perhaps there's a simpler alternative?
