推荐答案

根据此http://bytes.com/topic/c-sharp/answers/259010-reading-file-permissions [ ^ ].您可以通过Windows API和P/Invoke来执行此操作.

另请参见有用的相关小代码集: http://www.java2s .com/Tutorial/CSharp/0300__File-Directory-Stream/0240__File-Permission.htm [

There is no a managed way to acquire file/directory permissions (Access Control List), according to this http://bytes.com/topic/c-sharp/answers/259010-reading-file-permissions[^]. You can do this via Windows API and P/Invoke.

See also this, a useful set of related codelets: http://www.java2s.com/Tutorial/CSharp/0300__File-Directory-Stream/0240__File-Permission.htm[^].

Permission is not the only reason for inaccessible files.

However, do you really need to get into this sophisticated stuff? I have my own practical non-nonsense approach to this. I do access under try-catch block, catch access exception and process it the way I want. It is very practical, because it''s very hard to do all checks. This is exactly what structured exceptions are design for. As access to a new file system object does not happen often, there is no performance hit.
