I have 25 numbers coming up from 1 to 25, now I want it to
go from 25 to 1 with array.reverse. I get a reverse is not
a member of array. Help
 
This works just fine;-

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles Button1.Click

Dim myArray() As String = {"hello", "My", "Friend"}

Dim i As Integer
'Prints forward
For i = 0 To myArray.Length - 1

Debug.WriteLine(myArray(i))

' Next reverse array
myArray.Reverse(myArray)

'Prints reverse of original order using same loop as before
For i = 0 To myArray.Length - 1

Debug.WriteLine(myArray(i))

Next

End Sub
