반환 값

유형: System.Data.SqlTypes.SqlDouble
A SqlDouble value containing the total length.

If a SqlGeography instance is closed, its length is calculated as the total length around the instance; the length of any polygon is its perimeter, and the length of a point is 0. The length of a GeometryCollection is found by calculating the sum of the lengths of all of the SqlGeography instances contained within the collection.
