Inserts a copy of the specified Point at the specified point index in the specified ring of the Polygon.

Namespace:  ESRI.ArcGISExplorer.Geometry

Assembly:  ESRI.ArcGISExplorer (in ESRI.ArcGISExplorer.dll) Version: 2.0.0.1500 (2.0.0.1500)

Syntax

C#
public void InsertPoint(
	int ringIndex,
	int pointIndex,
	Point pt
)
Visual Basic (Declaration)
Public Sub InsertPoint ( _
	ringIndex As Integer, _
	pointIndex As Integer, _
	pt As Point _
)

Parameters

ringIndex
Type: System..::.Int32

The index of the ring to copy the new Point into.
pointIndex
Type: System..::.Int32

The point index within the specified ringIndex to copy the new Point into.
pt
Type: ESRI.ArcGISExplorer.Geometry..::.Point

The Point to copy into the Polygon.

Remarks

Use this method to insert a new Point into an existing ring of a multipart Polygon; the inserted point will have the specified pointIndex and all following points in the ring will increase their index position by 1. If the pointIndex is equal to the number of points, this method behaves like the AddPoint method, copying the Point after all existing points in the specified ring. The specified ringIndex must already exist in the Polygon.

If working with single part polygons, the InsertPoint(Int32, Point) overload is also available.

Note that the CoordinateSystem property of any new points added, inserted or set into existing an existing Polygon or Polyline will be discarded, and the coordinates (X and Y properties) of the point assumed to be in the same CoordinateSystem as the Polygon or Polyline to which they are added.

Exceptions

ExceptionCondition
System..::.ArgumentOutOfRangeExceptionThe specified pointIndex must not be greater than the number of existing points in the specified ring, and the specified ringIndex must already exist in the Polygon.
System..::.InvalidOperationExceptionA Point cannot be inserted into an empty Polygon.
