Summary

### Recap:
- `File.ReadAllText(filePath)` method returns all the content of a file in string form. It is useful when we want to retrieve all the text of a file;
- `File.ReadAllLines(filePath)` method returns all the content of a file in the form of an array of strings. It is useful when we want to retrieve all the text of a file already organized into an array based on lines;
- `StreamReader` object can be used for loading and reading a file line by line. It is useful when we want to read a file partially.
