Determines whether the specified object is equal to the current object.(Inherited from Object.)
Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)

Windows Presentation Foundation (WPF) hit testing only considers the filled area of a geometry during a hit test. If you create a point Geometry, the hit test would not intersect anything because a point has no area.
The following example shows how to set up a hit test using HitTest method. The Point value that is passed to the OnMouseDown method is used to create a Geometry object in order to expand the range of the hit test.for the
The IntersectionDetail property of GeometryHitTestResult provides information about the results of a hit test that uses a Geometry as a hit test parameter. The following illustration shows the relationship between the hit test geometry (the blue circle) and the target object (the red square).
