Trying to display a rectangular array (update)

I'm trying to do a tic-tac-toe console application for practice. I created a case statement for the user to pick which square they want to fill in.

Public Class TwoDi
    Shared Sub twodimension()
        Console.WriteLine("Do you want to go first?")
        first = Console.ReadLine()

        If first = "yes" Then
            Console.WriteLine("Please enter a X or O.")
            x2 = Console.ReadLine()

            Console.WriteLine("Pick a spot.")
            pickone(x2)
        End If
    End Sub

    Shared Sub pickone(ByVal x As String)
        Dim choice As String
        Dim tic(2, 2) As开发者_如何学编程 String
        Dim x2 As String
        Dim bound0 As Integer = tic.GetUpperBound(0)
        Dim bound1 As Integer = tic.GetUpperBound(1)
        Dim i As Integer
        Dim x1 As Integer
        Dim populate As String = "n"

        For i = 0 To bound0
          For x1 = 0 To bound1
            Console.Write("{0}", show)
          Next
         Console.WriteLine()
        Next

        x2 = x
        choice = Console.ReadLine()

        Select Case choice
            Case "middle"    //putting in one case statement for example.
                choice = "middle"
                tic(1, 1) = x2        
        End Select

        Console.Write("" & vbLf & "Pick a spot.")
        pickone(x2)
    End Sub
End Class

Now I tried a few loops to update the display to show the 3x3 2-d array. Specifically this one:

For i = 0 To bound0
    For x1 = 0 To bound1
        Console.Write("{0}", tic(bound0, bound1))
    Next
    Console.WriteLine()
Next

I prepopulate the 3x3 grid with "n" but when I run the loop it just shows a single x or o and not even spaced correctly.

Also a somewhat seperate question, when I loop to run a block of code again, is it best practice to just to call the Sub/Function again?

Addressing the "all filled with X or O depending if I pick a X or O" part:

Did you really mean to type Console.Write("{0}", tic(1, 1)) instead of maybe this?

For i = 0 To bound0
     For x1 = 0 To bound1
       Console.Write("{0}", tic(i, x1))
     Next
   Console.WriteLine()
Next
