Тип: System.Data.SqlTypes.SqlBoolean
A SqlBoolean value indicating whether the start and end points of the SqlGeography instance are the same. Returns true if both points are the same. Otherwise, false.

This method returns false if any figures of a geography instance are points, or if the instance is empty.
This method returns true for geography collection types if each contained SqlGeography instance is closed.
