passing data to an array

Question

I have to pass a whole load of values of personal info, eg name age height etc from a text file (.txt) into a vb array, what is the best way of doing this? There are probably around 10 pieces of info for each 'record' and approx 20 records. Do i have to declare an array and its size before hand, of or can this be done on a button click when the data is requested?
