Rectangle.IntersectsWith(Rectangle) Metodo

Definizione

Spazio dei nomi:

System.Drawing

Assembly:

System.Drawing.Primitives.dll

Origine:

Rectangle.cs

Determina se questo rettangolo interseca rect.

public:
 bool IntersectsWith(System::Drawing::Rectangle rect);

public readonly bool IntersectsWith (System.Drawing.Rectangle rect);

member this.IntersectsWith : System.Drawing.Rectangle -> bool

Public Function IntersectsWith (rect As Rectangle) As Boolean

Parametri

rect

Rectangle

Rettangolo da sottoporre a verifica.

Restituisce

Boolean

Questo metodo restituisce true se esiste un'intersezione; in caso contrario, restituisce false.

Esempio

Nell'esempio di codice seguente vengono illustrati i IntersectIsEmpty membri e IntersectsWith . Questo esempio deve essere usato con un Windows Form. Incollare questo codice in un modulo e chiamare questo metodo quando si gestisce l'evento del Paint modulo, passando e come PaintEventArgs.

private:
   void InstanceRectangleIntersection( 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 ) )
      {
         rectangle1.Intersect( rectangle2 );
         if (  !rectangle1.IsEmpty )
         {
            e->Graphics->FillRectangle( Brushes::Green, rectangle1 );
         }
      }
   }

private void InstanceRectangleIntersection(PaintEventArgs e)
{

    Rectangle rectangle1 = new Rectangle(50, 50, 200, 100);
    Rectangle rectangle2 = new Rectangle(70, 20, 100, 200);

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

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

  Private Sub InstanceRectangleIntersection( _
      ByVal e As PaintEventArgs)

      Dim rectangle1 As New Rectangle(50, 50, 200, 100)
      Dim rectangle2 As New Rectangle(70, 20, 100, 200)

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

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