File.ReadLines() method to read a text file that has lots of lines. File.ReadLines() method internally creates Enumerator. So we can call it in the foreach and every time foreach asks for a next value, it calls StreamReader.ReadLine under the hood.
C# Code: You can use File.ReadLines and foreach to read whole file line by line
