유형: Microsoft.SqlServer.Types.OpenGisGeometryType
OpenGisGeometryType object that indicates the type being created by the call sequence.
구현
IGeometrySink.BeginGeometry(OpenGisGeometryType)
주의
Call sequences that open with a BeginGeometry() must close with a EndGeometry().
BeginGeometry() and EndGeometry() pairs can be nested.
Valid values for type are Point, MultiPoint, LineString, MultiLineString, Polygon, MultiPolygon, and GeometryCollection.
The following example is a WKI (Well Known Interface) call sequence for a MultiLineString object.
