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

There are a number of things that could be going on.

First, make sure you properly dispose of the file writer (close isn't good enough) by utilizing the using clause around everything that implements IDisposable.

Second, it you are simply reading, make sure you have the correct flags set when opening the file.

To go any further it would help if you provided a code block which showed how you were accomplishing this; particularly around the reading of the file
