File is being used by another process

Question

I have a program that roughly does this:

1. open a file to read from it.
2. close the file
3. Start a filewatcher to watch for changes in the file.

Answer 1

The problem is that the FileSystemWatcher tells you immediately when the file was created. It doesn't wait for the file to be released. For instance, when you copy a large file which takes 3 seconds to copy, so you have to open the file after that.
