IPolygon
A polygon is a two-dimensional surface stored as a sequence of points that has a bounding ring and 0 or more interior rings. In addition to the other properties inherited from IGeometry, polygons have area.

Gets the number of interior rings. |
|
|
|
PointOnSurface |
An IPoint representing a point on the surface of the polygon. |

An IRings representing all of the polygon’s interior and exterior rings. |
|
|
|
An ISpatialOperator representing the selected geometry’s interaction with another geometry object. (Inherited from IGeometry) |
|
|
|
An ISpatialRelation that tests the geometry’s spatial relationship with other geometries. (Inherited from IGeometry) |
|
|
|
An IWks representing methods for transferring coordinate system information (WKT and WKB). (Inherited from IGeometry) |
|
|
|
Methods |
|
|
|
Creates an exact copy of the selected geometry. (Inherited from IGeometry) |
|
|
|
Terminates the edit item mode. (Inherited from IGeometry) |
|
|
|
Returns whether or not the set of points in the selected geometry is empty. (Inherited from IGeometry) |
|
|
|
Returns whether or not the geometry is simple. (Inherited from IGeometry) |
|
|
|
Removes all points from this geometry. (Inherited from IGeometry) |
|
|
|
Starts the edit item mode. (Inherited from IGeometry) |
Area
Gets the polygon’s area.

|
|
C# |
|
|
double Area { get; } |
|

HRESULT Area([out, retval] double* dArea) |

InteriorRing
Gets the ILinearRing in the specified zero-based index, representing a specific interior ring. This property is exposed in C# and JavaScript in the following ways:
§ In C#, this property is exposed as InteriorRing, e.g.,
IPolygon myPoly;
ILinearRing thisLinearRing = myPoly.InteriorRing[0];
Note: In older versions of C#, this property is exposed as get_InteriorRing, e.g.,
IPolygon myPoly;
ILinearRing thisLinearRing = myPoly.get_InteriorRing[0];
§ In JavaScript use:
var myPoly;
var thisLinearRing = myPoly.InteriorRing(0);
