  It is interesting to notice that the File.ReadAllText and File.ReadAllLines methods were added in the version 2.0 of the .NET framework; mainly because in the previous versions, the necessary usage of a Stream object made reading text files difficult and unintuitive for most of the developers.

  Good, what about case when I need to use the text line by line. Should I split it after that? or do I need to read it into array

  If you have a lot of processing to do within the file itself, the fastest way is to read the entire file contents into an array, close the file, then loop over the array using a Parallel.For loop.

  Benchmarks and sample code here to prove it’s the fastest way to go:
