Help reading from csv file!

I'm creating a program that reads values from a csv file and then displays them into a datagrid. The only problem is I have no clue how to do either of the two tasks, any help would be greatly appreciated.

.txt file is like this

John Doe, 15,17,15,18,19
John Deer, 18,16,82,16,19


I need each csv to be shown on each corresponding column, and I'm lost... :(

Thank you in advance
