Li,

Look at the File class, specifically the FileShare enumeration.

Li, I didn't give you the correct information. I was thinking about
something else (I'm doing that alot lately :| ) I actually don't know how
to do what you are looking for. You might try the FileIOPermission class,
or start there anyways.

I think there is no way to check it. You can try to open it using the needed
access permission. If it fails, the file is locked.

Or READ ONLY or in a READ ONLY directory--if on a network, this is VERY
possible.

I didn't say that only this error can occur. It is obvious that he/she has
to check /which/ exception was thrown.

One solution may be to check the timestamp of the file. If it's changed then it can be considered as available again.
