Determines if this rectangle intersects with rect
.
public:
bool IntersectsWith(System::Drawing::Rectangle rect);
public readonly 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
Parameters
- rect
- Rectangle
The rectangle to test.
Returns
This method returns true
if there is any intersection, otherwise false
.
Examples
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.
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
