Rectangle.Intersect Metode

Definisi

Ruang nama:

System.Drawing

Rakitan:

System.Drawing.Primitives.dll

Rectangle Menentukan struktur yang mewakili persimpangan dua persegi panjang.

Overload

Intersect(Rectangle, Rectangle)	Mengembalikan struktur ketiga Rectangle yang mewakili persimpangan dua struktur lainnya Rectangle . Jika tidak ada persimpangan, kosong Rectangle akan dikembalikan.
Intersect(Rectangle)	Mengganti ini Rectangle dengan persimpangan dirinya sendiri dan yang ditentukan Rectangle.

Intersect(Rectangle, Rectangle)

Sumber:

Rectangle.cs

Mengembalikan struktur ketiga Rectangle yang mewakili persimpangan dua struktur lainnya Rectangle . Jika tidak ada persimpangan, kosong Rectangle akan dikembalikan.

public:
 static System::Drawing::Rectangle Intersect(System::Drawing::Rectangle a, System::Drawing::Rectangle b);

public static System.Drawing.Rectangle Intersect (System.Drawing.Rectangle a, System.Drawing.Rectangle b);

static member Intersect : System.Drawing.Rectangle * System.Drawing.Rectangle -> System.Drawing.Rectangle

Public Shared Function Intersect (a As Rectangle, b As Rectangle) As Rectangle

Parameter

a

Rectangle

Persegi panjang untuk bersinggungan.

b

Rectangle

Persegi panjang untuk bersinggungan.

Mengembalikan

Rectangle

Rectangle yang mewakili persimpangan a dan b.

Contoh

Contoh kode berikut menunjukkan Intersect, IsEmpty dan IntersectsWith anggota. Contoh ini harus digunakan dengan Formulir Windows. Tempelkan kode ini ke dalam formulir dan panggil metode ini saat menangani peristiwa formulir Paint , meneruskan e sebagai 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
    End If
End Sub

public:
 void Intersect(System::Drawing::Rectangle rect);

public void Intersect (System.Drawing.Rectangle rect);

member this.Intersect : System.Drawing.Rectangle -> unit

Public Sub Intersect (rect As Rectangle)

Parameter

rect

Rectangle

yang Rectangle akan bersinggungan.
