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.
