ArcGIS.Core.Geometry Namespace / LineBuilderEx Class / LineBuilderEx Constructor / LineBuilderEx Constructor(Coordinate2D,Coordinate2D,SpatialReference)
The start point.
The end point.
(Optional) The spatial reference. The default value is null.
Example

In This Topic
    LineBuilderEx Constructor(Coordinate2D,Coordinate2D,SpatialReference)
    In This Topic
    Creates a new instance of the LineBuilderEx class defined from the start and end point.
    Syntax

    Parameters

    startPoint
    The start point.
    endPoint
    The end point.
    spatialReference
    (Optional) The spatial reference. The default value is null.
    Exceptions
    ExceptionDescription
    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;
