名稱 Description
Intersect(Rectangle, Rectangle)

回傳第三 Rectangle 個結構，代表兩個結構 Rectangle 的交集。 若無交叉點，則返回空 Rectangle 位。
Intersect(Rectangle)

將此 Rectangle 取代為自身與指定 Rectangle的交集。

範例

以下程式碼範例展示了 Intersect、 以及 IsEmpty 成員。IntersectsWith 此範例應用於 Windows 表單。 將此程式碼貼入表單，並在處理表單 Paint 事件時呼叫此方法，傳遞 e 為 PaintEventArgs。

private:
   void StaticRectangleIntersection( PaintEventArgs^ e )
   {
      Rectangle rectangle1 = Rectangle(50,50,200,100);
      Rectangle rectangle2 = Rectangle(70,20,100,200);
      e->Graphics->DrawRectangle( Pens::Black, rectangle1 );
      e->Graphics->DrawRectangle( Pens::Red, rectangle2 );
      if ( rectangle1.IntersectsWith( rectangle2 ) )
      {
         Rectangle rectangle3 = Rectangle::Intersect( rectangle1, rectangle2 );
         if (  !rectangle3.IsEmpty )
         {
            e->Graphics->FillRectangle( Brushes::Green, rectangle3 );
         }
      }
   }

private void StaticRectangleIntersection(PaintEventArgs e)
{
    Rectangle rectangle1 = new Rectangle(50, 50, 200, 100);
    Rectangle rectangle2 = new Rectangle(70, 20, 100, 200);
    Rectangle rectangle3 = new Rectangle();

    e.Graphics.DrawRectangle(Pens.Black, rectangle1);
    e.Graphics.DrawRectangle(Pens.Red, rectangle2);

    if (rectangle1.IntersectsWith(rectangle2))
    {
        rectangle3 = Rectangle.Intersect(rectangle1, rectangle2);
        if (!rectangle3.IsEmpty)
        {
            e.Graphics.FillRectangle(Brushes.Green, rectangle3);
        }
    }
}

Private Sub StaticRectangleIntersection(ByVal e As PaintEventArgs)
    Dim rectangle1 As New Rectangle(50, 50, 200, 100)
    Dim rectangle2 As New Rectangle(70, 20, 100, 200)
    Dim rectangle3 As New Rectangle

    e.Graphics.DrawRectangle(Pens.Black, rectangle1)
    e.Graphics.DrawRectangle(Pens.Red, rectangle2)

    If (rectangle1.IntersectsWith(rectangle2)) Then
        rectangle3 = Rectangle.Intersect(rectangle1, rectangle2)
        If Not rectangle3.IsEmpty Then
            e.Graphics.FillRectangle(Brushes.Green, rectangle3)
        End If
