In This Topic
    Copy2DCoordinatesToList Method (Multipoint)
    In This Topic
    Gets a copy of all the points as a read-only list of 2D coordinates.
    Syntax
    public IReadOnlyList<Coordinate2D> Copy2DCoordinatesToList()
    Public Function Copy2DCoordinatesToList() As IReadOnlyList(Of Coordinate2D)

    Return Value

    A readonly list of Coordinate2D.
    Example
    Modify the points of a Multipoint
    // assume a multiPoint has been built from 4 points
    // the modified multiPoint will have the first point removed and the last point moved
    
    // use the builderEx constructors = don't need to run on the MCT.
    MultipointBuilderEx builderEx = new MultipointBuilderEx(multipoint);
    // remove the first point
    builderEx.RemovePoint(0);
    // modify the coordinates of the last point
    var ptEx = builderEx.GetPoint(builderEx.PointCount - 1);
    builderEx.RemovePoint(builderEx.PointCount - 1);
    
    var newPtEx = MapPointBuilderEx.CreateMapPoint(ptEx.X + 1.0, ptEx.Y + 2.0);
    builderEx.AddPoint(newPtEx);
    Multipoint modifiedMultiPointEx = builderEx.ToGeometry() as Multipoint;
    
    Retrieve Points, 2D Coordinates, 3D Coordinates from a multipoint
    ReadOnlyPointCollection points = multipoint.Points;
    IReadOnlyList<Coordinate2D> coords2d = multipoint.Copy2DCoordinatesToList();
    IReadOnlyList<Coordinate3D> coords3d = multipoint.Copy3DCoordinatesToList();
