Visual Basic 2010 Express - Loading CSV Value into a 2 Dimensional Array and explaining to me how it works

I am new to Visual Basic and am self-learning how to write VB.net applications in Visual Studio 2010 Express. I need someone to help me finish writing this small amount of code, as well as explain to me how it works. I am writing a Visual Basic 2010 Express console application that does the following: 1) Using TextFieldParser to read a CSV file with 2150 comma delimited values, all integers 2) Take each of those integers and place them into a 2-Dimensional Array, where the array will be set up like this: Array (x, y) where x is 0 to 49, and y is 0 to 42 (total 2150 values). When the CSV file is being read, x will increment by 1, when 43 (0 to 42) values have been loaded, then when x = 2, the next 43 values will be loaded (with y incrementing by 1) I have written the code so far to read the CSV file, however I need to be able to load that into the 2D array. Can you please help me load these values into a 2D array? I have attached the code of what I have made so far, as well as a copy of the CSV file that is being read. Thanks!
