範例
下列程式碼範例會示範如何使用 Subtract 方法。 若要執行此範例,請將它貼到 Windows Form 中。 處理表單的事件 Paint ,並從事件處理方法呼叫 SubtractSizes
方法 Paint ,並傳遞 e
為 PaintEventArgs。
private void SubtractSizes(PaintEventArgs e)
{
Size size1 = new Size(100, 100);
Size size2 = new Size(50, 50);
e.Graphics.DrawRectangle(Pens.Black, new Rectangle(new Point(10, 10), size1));
size1 = Size.Subtract(size1, size2);
e.Graphics.DrawRectangle(Pens.Red, new Rectangle(new Point(10, 10), size1));
}
Private Sub SubtractSizes(ByVal e As PaintEventArgs)
Dim size1 As New Size(100, 100)
Dim size2 As New Size(50, 50)
e.Graphics.DrawRectangle(Pens.Black, _
New Rectangle(New Point(10, 10), size1))
size1 = System.Drawing.Size.Subtract(size1, size2)
e.Graphics.DrawRectangle(Pens.Red, _
New Rectangle(New Point(10, 10), size1))
End Sub
