示例1: New
Shared Sub New()
Aquarium.AquariumSizeKey.OverrideMetadata(GetType(Aquarium), New PropertyMetadata(Double.NaN, Nothing, New CoerceValueCallback(AddressOf CoerceFishbowlAquariumSize)))
End Sub
Private Shared Function CoerceFishbowlAquariumSize(ByVal d As DependencyObject, ByVal baseValue As Object) As Object
'Aquarium is 2D, a Fishbowl is a round Aquarium, so the Size we return is the ellipse of that height/width rather than the rectangle
Dim fb As Fishbowl = CType(d, Fishbowl)
'other constraints assure that H,W are positive
Return Convert.ToInt32(Math.PI * (fb.Width / 2) * (fb.Height / 2))
End Function
