Sorting Arrays before going into a combobox

[silky]

I need to sort the arrays in to alphabetical order the one holds products and the other the corresponding prices.

Here is the code for the split
Do While sr.Peek <> -1
myArray = Split(sr.ReadLine, ",")
cboProduct.Items.Add(myArray(0))
PriceArray(counter) = myArray(1)
counter = counter + 1
Loop
sr.Close()

where would I put the sort?
