【问题描述】：

现在如果我点击按钮 A，按钮 B 会显示 DropShadow 效果：

 Private Sub ButtonA_Click(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs) Handles ButtonA.Click

 Dim objDropShadow As New DropShadowEffect
            objDropShadow.ShadowDepth = 0
            objDropShadow.BlurRadius = 30
            objDropShadow.Color = Colors.GreenYellow

            Me.ButtonB.Effect = objDropShadow

End Sub

如果我点击了按钮 C，我将如何从按钮 B 中移除 DropShadow 效果？
