Using polymorphism in VB

Question

been struggling to find a solution to this...

What is the equivalent of the following c# in vb?

var v = something as control;

Been trying for a while and haven't really found much, the following is what i have managed to get to so far.

If TypeOf ctrl Is Control Then
   'what to put here? 
   ctrl = ctrl as control??? 'nope...      
End If

   ctrl = Directcast(ctrl, control)
End If

Found a solution that seems to work well.

If TypeOf ctrl Is Control Then
    ctrl = CType(ctrl, Control)
End If

using explicit Casting.
