Comentários
When this method is used on a subtype of a GeometryCollection, such as MultiPoint or MultiLineString, this method returns the SqlGeography instance if called with N=1.
This method returns null if the parameter is larger than the result of STNumGeometries and will throw an ArgumentOutOfRangeException if the expression parameter is less than 1.
