Rect::Intersect Method (Rect)

 

Finds the intersection of the current rectangle and the specified rectangle, and stores the result as the current rectangle.

Namespace:   System.Windows
Assembly:  WindowsBase (in WindowsBase.dll)

public:
void Intersect(
	Rect rect
)

Parameters

rect
Type: System.Windows::Rect

The rectangle to intersect with the current rectangle.

If no intersection exists, the current rectangle becomes Rect::Empty.

The following example shows how to use the Intersect(Rect) method to find the intersection of two rectangles and store the result as a rectangle.

private Rect intersectExample1()
{
    // Initialize new rectangle.
    Rect myRectangle = new Rect();

    // The Location property specifies the coordinates of the upper left-hand 
    // corner of the rectangle. 
    myRectangle.Location = new Point(10, 5);

    // Set the Size property of the rectangle with a width of 200
    // and a height of 50.
    myRectangle.Size = new Size(200, 50);

    // Create second rectangle to compare to the first.
    Rect myRectangle2 = new Rect();
    myRectangle2.Location = new Point(0, 0);
    myRectangle2.Size = new Size(200, 50);

    // Intersect method finds the intersection between the current rectangle and the 
    // specified rectangle, and stores the result as the current rectangle. If no 
    // intersection exists, the current rectangle becomes the Empty rectangle. 
    // myRectangle now has a size of 190,45 and location of 10,5. 
    myRectangle.Intersect(myRectangle2);

    // myRectangle has been changed into the intersection area between the old myRectangle
    // and myRectangle2 (new size of 190,45 and new location of 10,5).
    return myRectangle;
