ArcGIS.Core.Geometry Namespace / GeometryBag Class / Geometries Property
Example

In This Topic
    Geometries Property (GeometryBag)
    In This Topic
    Gets a list of geometries in this GeometryBag.
    Syntax
    public IReadOnlyList<Geometry> Geometries {get;}
    Public ReadOnly Property Geometries As IReadOnlyList(Of Geometry)
    Remarks
    An Envelope is converted to a Polygon when it is inserted into a GeometryBag. When retrieving an Envelope from a GeometryBag, it will be a Polygon.
    Example
    Construct GeometryBag
    MapPoint point = MapPointBuilderEx.CreateMapPoint(1, 2, SpatialReferences.WebMercator);
    
    List<Coordinate2D> coords2D = new List<Coordinate2D>()
    {
      new Coordinate2D(0, 0),
      new Coordinate2D(0, 1),
      new Coordinate2D(1, 1),
      new Coordinate2D(1, 0)
    };
    
    Multipoint multipoint = MultipointBuilderEx.CreateMultipoint(coords2D, SpatialReferences.WGS84);
    Polyline polyline = PolylineBuilderEx.CreatePolyline(coords2D, SpatialReferences.WebMercator);
    
    GeometryBagBuilderEx builder = new GeometryBagBuilderEx(SpatialReferences.WGS84);
    
    GeometryBag emptyBag = builder.ToGeometry();
    // emptyBag.IsEmpty = true
    
    builder.AddGeometry(point);
    // builder.GeometryCount = 1
    
    GeometryBag geometryBag = builder.ToGeometry();
    // geometryBag.PartCount = 1
    // geometryBag.PointCount = 1
    // geometryBag.IsEmpty = false
    
    IReadOnlyList<Geometry> geometries = geometryBag.Geometries;
    // geometries.Count = 1
    // geometries[0] is MapPoint with a sr of WGS84
    
    bool isEqual = geometryBag.IsEqual(emptyBag);   // isEqual = false
    
    builder.InsertGeometry(0, multipoint);
    geometryBag = builder.ToGeometry();
    // geometryBag.PartCount = 2
    
    geometries = geometryBag.Geometries;
    // geometries.Count = 2
    // geometries[0] is Multipoint
    // geometries[1] is MapPoint
    
    builder.AddGeometry(polyline);
    builder.RemoveGeometry(1);
    geometryBag = builder.ToGeometry();
    // geometryBag.PartCount = 2
    
    geometries = geometryBag.Geometries;
    // geometries.Count = 2
    // geometries[0] is Multipoint
    // geometries[1] is Polyline
