Rectangle.IntersectsWith(Rectangle) Rectangle.IntersectsWith(Rectangle) Rectangle.IntersectsWith(Rectangle) Rectangle.IntersectsWith(Rectangle) Method


Determines if this rectangle intersects with rect.

 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


Rectangle Rectangle Rectangle Rectangle

The rectangle to test.


This method returns true if there is any intersection, otherwise false.


The following code example demonstrates the Intersect, IsEmpty and the IntersectsWith members. This example should be used with a Windows Form. Paste this code into a form and call this method when handling the form's Paint event, passing e as PaintEventArgs.

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