Splitting a string into chunks of a certain size
...meone that just wants to look at a solution to this problem. A person must now understand what the Enumerable.Range() and .Select() functions do. I will not argue that you should have an understanding of that to write C#/.NET code as these functions have been in the BCL for many years now.
