Consider the following where class "Circle" inherits from "Shape":

dim objListOfCircles as new List(of Circle)

DrawShapes(objListOfCirlces)


Private sub DrawShapes(byref objListOfShapes as List(of Shape))

for each objShape as Shape in objListOfShapes
  objShape.Draw()
next 

end sub

I can't get this to work. What is the explaination as to why this doesn't work?
