问题
In the application I am writing, the user has the ability to add some folder to search for some files recursively.
The problem is the files he wants to add to the app might be stored in the base drive like K:. So if he add this drive directly, I get an exception.
Or if he adds C:\, then I get UnauthorizedAccessException where it says:
Access to the path 'C:\System Volume Information' is denied.
How can I just scan where I can scan? And give the ability to scan another non-system drive fully (all directories)?
回答1:
Catch the exception, ignore it, and move on to the next directory.
回答2:
Why does this not work for me then. I try/catch the unauthorizedAccessException and it still just stops the program.
