I am using the following code to split a string and retrieve them:
Private Sub Button1_Click(sender As Object, e As EventArgs)
Handles Button1.Click
You already have each part - just display it:
For Each part In parts
MsgBox(part)
Next
part(0)
will return the first item in the character collection that is a string.
If you want a specific index into the returned string array (as suggested by your comment), just access it directly:
Dim parts As String() = s.Split(New Char() {","c})
Dim firstPart As String = parts(0)
Dim thirdPart As String = parts(2)
