Run Code as Admin... (find option in IDE).

Answer 3

Try to make it smaller.

Try to create a file in "d:\", do you have rights there ?
if you use : Directory.getfiles(@"d:\"); does it work ?

If the small thing is working, you can go bigger.

SearchAllDirectory is a pretty huge area, you probably do not have access everywhere.

Thank you, @sneeze. :)
I just follow your suggestions.
and found that it is a problem of permission like @ValentinHacker's mention above. because when i skip secured folder, it work well.
