Definizione

Spazio dei nomi:
System.Drawing
Assembly:
System.Drawing.dll
Assembly:
netstandard.dll

Determina se questo rettangolo si interseca con rect.

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

Valori restituiti

Boolean

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

Esempio

Nell'esempio di codice seguente vengono illustrati i Intersectmembri e IsEmptyIntersectsWith . Questo esempio deve essere usato con un modulo Windows. 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
