Try This,

VB

Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        Dim Readtxt As String = "1,2,3,4,5"
        Dim arrTxt() As String = Split(Readtxt, ",")
        Dim arrLength As Integer = arrTxt.Length
        Dim arrNumber(arrLength - 1) As Integer
        For i As Integer = 0 To arrLength - 1
            arrNumber(i) = Integer.Parse(arrTxt(i))
            
        Next
    End Sub

Solution 1

What is the problem? For each itme of the array of strings use Int32.Parse[^] (or TryParse[^]) method to convert the string into a number and add the obtained number to the integer array.
You may also skip the 'fill-the-array-of-strings' step and produce directly the array of integers.

This is correct, a 5.
However, there is a library generic method to do in in one line of code. Please see my answer.

Solution 2

Essentially, you should create an array of the target type and convert it element by element, in a loop. However, there is a convenient universal generic method in .NET FCL, to do it in one line of code: http://msdn.microsoft.com/en-us/library/exc45z53.aspx[^].
