[Resolved] Fastest way to comapre lines in a txt files

[goldenix]

i would like to know whats the fastest way to compare lines in txt files? ( assume both files have around 1 million lines ) (ya im comparing registry files)

This is how im planning to do it atm:

 My.Computer.FileSystem.ReadAllText(BOTH FILES)

 Dim array1() As String
 array1 = Split(file1, vbNewLine) etc. for array2

Loop through both arrays & compare lines:
