Definição

Namespace:

System.Drawing

Assembly:

System.Drawing.Primitives.dll

Origem:

Rectangle.cs

Determina se esse retângulo faz interseção com 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

Parâmetros

rect

Rectangle

O retângulo a ser testado.

Retornos

Boolean

Esse método retorna true se houver alguma interseção, caso contrário, false.

Exemplos

O exemplo de código a seguir demonstra os Intersectmembros e IntersectsWith . IsEmpty Este exemplo deve ser usado com um Formulário do Windows. Cole esse código em um formulário e chame esse método ao manipular o evento do Paint formulário, passando e como 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
