Why do we need to use the DirectoryInfo class?

There were a lot of new classes that I've not been familar with, so I was researching them one by one.

            string currentDirectory = Directory.GetCurrentDirectory();
            DirectoryInfo directory = new DirectoryInfo(currentDirectory);

            var fileName = Path.Combine(directory.FullName, "SoccerGameResults.csv");
            var fileContents = ReadFile(fileName);

It looks like in the code we wrote directory.FullName returns a string and is identical to the string currentDirectory.
That is, so far as I can tell, we didn't need to make the DirectoryInfo object at all.

Is the directory not also used for other things later in the code? If not, you may have found a bug! :beetle:

You might want to submit this using the instructions on the Support page.

I also notice that there wasn't a need to use the DirectoryInfo class. Although I know that using DirectoryInfo gives us lots of instance methods, they were not used in the video.

Using Directory.GetCurrentDirectory() was sufficient to get the working directory path.

It did confuse/clutter things a bit.
