The end point.
(Optional) The SpatialReference. The default value is null.
Example Version

CreateLineSegment(Coordinate2D,Coordinate2D,SpatialReference) Method
Convenience method to create a new instance of the LineSegment class.
Syntax

Parameters

startPoint
The start point.
endPoint
The end point.
spatialReference
(Optional) The SpatialReference. The default value is null.

Return Value

Exceptions
ExceptionDescription
startPoint or endPoint is null or empty.
Remarks
The new instance will build 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;
