How to split a string by x amount of characters

Question

I have a program where a user enters a list of numbers in the form of a string. This list of numbers is always a multiple of 8.

So the list can contain 8, 16, 32, 40

Answer 1

This should split the string into an array of 8-character substrings

Dim orig = "12344321678900987"
Dim res = Enumerable.Range(0,orig.Length\8).[Select](Function(i) orig.Substring(i*8,8))
