Hi oompa,
I don't see where you switch between spaces and commas.. but fine, it
doesn't really matter.
The difference between Lists and Arrays is that Lists are just
wrappers around arrays and they make it easier to manage them.
Dim parts As String() = line.Split(",".ToCharArray())
Dim label As String = parts(0)
Dim area As Double = Convert.ToDouble(parts(1))
Dim pieValuesStr As String() = parts(2).Split(" ".ToCharArray())
Dim pieValuesDbl As New List(Of Double)
For Each value As String in pieValuesStr
pieValuesDbl.Add(Convert.ToDouble(value))
Next
