Rect.IntersectsWith Method (Rect)


The .NET API Reference documentation has a new home. Visit the .NET API Browser on to see the new experience.

Indicates whether the specified rectangle intersects with the current rectangle.

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

public bool IntersectsWith(
	Rect rect


Type: System.Windows.Rect

The rectangle to check.

Return Value

Type: System.Boolean

true if the specified rectangle intersects with the current rectangle; otherwise, false.

The following example shows how to use the IntersectsWith method to determine if two rectangles intersect.

private bool intersectsWithExample()
    // 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);

    // IntersectsWith method indicates whether the specified rectangle intersects 
    // with this rectangle. doesIntersect returns true because the two rectangles
    // intersect. 
    bool doesIntersect = myRectangle.IntersectsWith(myRectangle2);

    // Returns true.
    return doesIntersect;
