public SqlBoolean STIsValid()

반환 값

유형: System.Data.SqlTypes.SqlBoolean
Returns true if a SqlGeometry instance is well-formed, based on its Open Geospatial Consortium (OGC) type. Returns false if a SqlGeometry instance is not well-formed.

The OGC type of a SqlGeometry instance can be determined by invoking STGeometryType.

SQL Server produces only valid SqlGeometry instances, but allows for the storage and retrieval of invalid instances. A valid instance that represents the same point set of any invalid instance can be retrieved using the MakeValid method.
