    Members
    MemberDescription
    EnvelopeEnvelope geometry. See Envelope.
    GeometryBagBag of geometries. See GeometryBag.
    MultipatchMultiPatch 3D surface. See Multipatch.
    MultipointMultipoint geometry. See Multipoint.
    PointPoint geometry. See MapPoint.
    PolygonPolygon geometry. See Polygon.
    PolylinePolyline geometry. See Polyline.
    Unknown Unknown type. There will be no Geometry instance existing with this type.
    Example
    Get the individual parts of a multipart feature
    /// <summary>
    /// This method takes an input multi part geometry and breaks the parts into individual standalone geometries.
    /// This method must be called on the MCT. Use QueuedTask.Run.
    /// </summary>
    /// <param name="inputGeometry">The geometry to be exploded into the individual parts.</param>
    /// <returns>An enumeration of individual parts as standalone geometries. The type of geometry is maintained, i.e.
    /// if the input geometry is of type Polyline then each geometry in the return is of type Polyline as well.
    /// If the input geometry is of type Unknown then an empty list is returned.</returns>
    /// <remarks>This method must be called on the MCT. Use QueuedTask.Run.</remarks>
