Hi, i've seen many article on encrypt/decrypt of file and typically a button is used to choose the file for encrypt and another button to decrypt the file.

i've seen some application like truecrypt and probably others which does file encryption on-the-fly with transparent. this means that when a encrypted file is clicked to access, it will automatically decrypt and play/open the file. then when the file is closed, it will automatically encrypt again.

some have said that the only way to detect file open is through file system filter.

but is there other ways to do this in c# compact framework?

The dynamic type in C# 4.0 is a welcome addition to the language.
