Public Class Geometry |
Remarks
A geometry is an object defining a geometric shape. It provides access to properties and methods shared by all geometric objects; for example the center of the shape (GetCenter()()()), the bounding box of the shape (GetEnvelope()()()), and also the CoordinateSystem associated with the geometry which helps locate it exactly on the earth.
The Geometry class is a superclass for all classes representing different types of geometrical shapes in ArcGIS Explorer; Point, Multipoint, Polygon, Polyline, Envelope, and Multipatch.
A Geometry is returned from various members which can store different types of geometrical shape, for example Row.Geometry, Filter.Geometry, and Graphic.Geometry. Use the GeometryType property to determine which type of geometry is referenced (or alternatively try casting).
