LineBuilderEx Constructor(MapPoint,MapPoint,SpatialReference)

In This Topic

Creates a new instance of the LineBuilderEx class defined from the start and end point.

Syntax

C#
Visual Basic (Declaration)

public LineBuilderEx( 
   MapPoint startPoint,
   MapPoint endPoint,
   SpatialReference spatialReference
)

Public Function New( _
   ByVal startPoint As MapPoint, _
   ByVal endPoint As MapPoint, _
   Optional ByVal spatialReference As SpatialReference _
)

Parameters

startPoint: The start point.
endPoint: The end point.
spatialReference: (Optional) The spatial reference. The default value is null. The spatial references of the start point and end point are ignored.

Exceptions

Exception	Description
System.ArgumentNullException	startPoint or endPoint is null or empty.

Remarks

This is a straight line segment between the start and end point.

Line Segment

Example

Construct a LineSegment using two MapPoints

// Use a builderEx convenience method or use a builderEx constructor.

MapPoint startPt = MapPointBuilderEx.CreateMapPoint(1.0, 1.0);
MapPoint endPt = MapPointBuilderEx.CreateMapPoint(2.0, 1.0);

// BuilderEx convenience methods don't need to run on the MCT.
LineSegment lineFromMapPoint = LineBuilderEx.CreateLineSegment(startPt, endPt);

// coordinate2D
Coordinate2D start2d = (Coordinate2D)startPt;
Coordinate2D end2d = (Coordinate2D)endPt;

LineSegment lineFromCoordinate2D = LineBuilderEx.CreateLineSegment(start2d, end2d);

// coordinate3D
Coordinate3D start3d = (Coordinate3D)startPt;
Coordinate3D end3d = (Coordinate3D)endPt;

LineSegment lineFromCoordinate3D = LineBuilderEx.CreateLineSegment(start3d, end3d);

// lineSegment
LineSegment anotherLineFromLineSegment = LineBuilderEx.CreateLineSegment(lineFromCoordinate3D);


// builderEx constructors don't need to run on the MCT
LineBuilderEx lbEx = new LineBuilderEx(startPt, endPt);
lineFromMapPoint = lbEx.ToSegment() as LineSegment;

lbEx = new LineBuilderEx(start2d, end2d);
lineFromCoordinate2D = lbEx.ToSegment() as LineSegment;

lbEx = new LineBuilderEx(start3d, end3d);
lineFromCoordinate3D = lbEx.ToSegment() as LineSegment;

lbEx = new LineBuilderEx(startPt, endPt);
lineFromMapPoint = lbEx.ToSegment() as LineSegment;

lbEx = new LineBuilderEx(lineFromCoordinate3D);
anotherLineFromLineSegment = lbEx.ToSegment() as LineSegment;
