Sorting Arrays before going into a combobox

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?

If you need to keep them synced up then that maybe be a bit of trouble (since they aren't in the same array), but you can easily sort an array with the sort method.

VB Code:

Dim names() As String = {"Dan", "Ed", "Mike", "Cookie", "Claire"}
        Array.Sort(names)
        ListBox1.Items.AddRange(names)

Here is another example using an array of objects and sorting by an array of one of the field/properties.

VB Code:

Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
        Dim numbers() As Single = {1.5, 2, 5, 2.75, 3.3}
        Dim items() As Object = {New DualList("Dan", 1.5), New DualList("Ed", 2), New DualList("Mike", 5), New DualList("Cookie", 2.75), New DualList("Calire", 3.3)}
        Array.Sort(numbers, items)
        ListBox1.Items.AddRange(items)
    End Sub
 
End Class
 
Public Class DualList
    Public Name As String
    Public Number As Single
 
    Public Sub New(ByVal name As String, ByVal num As Single)
        Me.Name = name
        Me.Number = num
    End Sub
 
    Public Overrides Function ToString() As String
        Return Name & " {" & Number & "}"
    End Function
End Class
