Use String.Split and Int32.Parse in this Linq query:

Dim intArr = str.Split(","c).Select(Function(s) Int32.Parse(s)).ToArray()

or, if you find the query-syntax easier:

Dim ints = From str In str.Split(","c)
           Select Int32.Parse(str)
dim intArr = ints.ToArray()

here the old approach without Linq but correctly sized array:

Dim strArr = str.Split(","c)
Dim intArr(strArr.Length - 1) As Int32
For i As Int32 = 0 To strArr.Length - 1
    intArr(i) = Int32.Parse(strArr(i))
