You can't delete the file for very good reasons. Suppose that an accounting process is busy reading from the file to create ledger entries and you take the file out from underneath them - all of a sudden the ledger will not balance. In this case, Windows is trying to protect you.

If you must delete the file, then theoretically you could issue a DEL filename command (the equivalent of calling DEL at the command prompt) through Process.Start. The alternative is to kill the lock on the file using a much more complex process which involves a lot of p/invoking.

All correct, a 5.
I added more useful information to it. OP cannot delete the file, but can take care about the situation. Please see my answer.
you cannot. when a file is open, it is locked by os. you cannot rename, delete, move that file. As I understand, you don't close that file after using it. first close file and all references to it, then you can delete it.
You cannot delete such files, but you can take care about it. Please see my past answer:
File used by another process exception[^].
