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;
