この例は、Windows フォームでの使用を意図してデザインされています。この例を実行するには、このコードをフォームに貼り付けて、フォームの Paint イベント処理で AddShadow メソッドを呼び出します。フォームに listBox1 という名前の ListBox が含まれていることを確認します。
Private Sub AddShadow(ByVal e As PaintEventArgs) ' Create two SizeF objects. Dim shadowSize As SizeF = Size.op_Implicit(listBox1.Size) Dim addSize As New SizeF(10.5F, 20.8F) ' Add them together and save the result in shadowSize. shadowSize = SizeF.op_Addition(shadowSize, addSize) ' Get the location of the ListBox and convert it to a PointF. Dim shadowLocation As PointF = Point.op_Implicit(listBox1.Location) ' Add a Size to the Point to get a new location. shadowLocation = PointF.op_Addition(shadowLocation, New Size(5, 5)) ' Create a rectangleF. Dim rectFToFill As New RectangleF(shadowLocation, shadowSize) ' Create a custom brush using a semi-transparent color, and ' then fill in the rectangle. Dim customColor As Color = Color.FromArgb(50, Color.Gray) Dim shadowBrush As SolidBrush = New SolidBrush(customColor) e.Graphics.FillRectangles(shadowBrush, _ New RectangleF() {rectFToFill}) ' Dispose of the brush. shadowBrush.Dispose() End Sub
private void AddShadow(PaintEventArgs e) { // Create two SizeF objects.

private void AddShadow(PaintEventArgs e) { // Create two SizeF objects. SizeF shadowSize = Size.op_Implicit(listBox1.get_Size()); SizeF addSize = new SizeF(10.5F, 20.8F); // Add them together and save the result in shadowSize. shadowSize.set_Width(shadowSize.get_Width() + addSize.get_Width()); shadowSize.set_Height(shadowSize.get_Height() + addSize.get_Height()); // Get the location of the ListBox and convert it to a PointF. PointF shadowLocation = Point.op_Implicit(listBox1.get_Location()); // Add two points to get a new location. shadowLocation.set_X(shadowLocation.get_X() + (new Size(5, 5).get_Width())); shadowLocation.set_Y(shadowLocation.get_Y() + (new Size(5, 5).get_Height())); // Create a rectangleF. RectangleF rectFToFill = new RectangleF(shadowLocation, shadowSize); // Create a custom brush using a semi-transparent color, and // then fill in the rectangle.
