Replaces the Point at the specified index within the Polyline with a copy of the specified Point. If the Polyline has more than one path, the Point is set into the first path.

Namespace:  ESRI.ArcGISExplorer.Geometry

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

Syntax

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

Parameters

pointIndex
Type: System..::.Int32

The index of the existing Point to replace.
pt
Type: ESRI.ArcGISExplorer.Geometry..::.Point

The Point to set into the pointIndex.

Remarks

Use this method to set a new Point into a Polyline by replacing an existing Point (instead of using RemovePointAt followed by InsertPoint); the new point will have the specified pointIndex and all other existing points in the Polyline remain the same.

For a multipart Polyline, the Point is set into the first path; if working with multipart polylines, see the SetPoint(Int32, Int32, Point) overload in which a path index can be specified to set the new Point into.

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 exist in the Polyline.
