Convert stored string of numbers to an array of integers

Question

I have a comma string of numbers inside var named num_str

the contents of num_str look like this: "1,2,3,4,5", etc.

I'm looking for a way to add num_str to an expression to convert the number of numbers it contains into an array of integers

I want to make sure I can just refer to 'num_str' to get numbers instead of writing like {"1,2,3,4,5"}

I tried this where 'num_str' contains numbers

Dim test As String = Nothing
Dim result() As Integer = Int32.TryParse(num_str.Split(","c))
For i = 0 To result.Length - 1
   test += result(i)
Next

but it does not work

what I'm looking for is a result with an array of numbers

Answer 1

Dim totalValue = str.
                 Split(","c).
                 Select(Function(n) Integer.Parse(n)).
                 Sum()

Answer 2

Try creating an integer array

Dim numbers = str.Split(","c).[Select](Function(n) Integer.Parse(n)).ToList()

Dim num_str As String = ...
Dim str() As String = num_str.Split(",")
Dim result(str.Length - 1) As Integer
For i = 0 To str.Length - 1
    result(i) = str(i)
Next
