Возвращаемое значение
Тип: System.Data.SqlTypes.SqlBoolean
Returns true if the start and end points of the given SqlGeometry instance are the same. Returns false if the instance is not closed, if any figures of the instance are points, or if the instance is empty.Returns true for geometry collection types if each contained SqlGeometry instance is closed. Otherwise, false.
Замечания
All Polygon instances are considered closed.
