Microsoft.SqlServer.Types 命名空间

The Microsoft.SqlServer.Types namespace contains classes used when working with the HierarchyID data type and the spatial data types, such as the geometry and geographic data types.

	GeographyConvexHullAggregate	基础结构。Represents the convex hull for the given set of SqlGeography objects.
	GeographyEnvelopeAggregate	基础结构。Represents a geography envelope from the given set of SqlGeography objects.
	GeographyTessellationFunction	基础结构。Represents the geography tessellation functions.
	GeographyUnionAggregate	基础结构。Represents a union of a set of SqlGeography objects.
	GeometryCollectionAggregate	基础结构。Represents a geometry collection from the given set of SqlGeometry objects.
	GeometryConvexHullAggregate	基础结构。Represents the convex hull for the given set of SqlGeometry objects.
	GeometryEnvelopeAggregate	基础结构。Represents a geometry envelope based on the given set of SqlGeometry objects.
	GeometryTessellationFunction	基础结构。Provides static methods for creating a geometry tessellation.
	GeometryUnionAggregate	基础结构。Represents a union from a set of SqlGeometry objects.
	HierarchyIdException	The exception that is thrown for invalid SqlHierarchyId values.
	SpaceFillingCurve	基础结构。Provides methods for calculating a space-filling curve.
	SpatialGridCoverage	基础结构。Provides methods for obtaining a spatial grid coverage.
	SpatialTessellationFunction	基础结构。Provides static methods for creating a spatial tessellation.
	SqlGeography	The SqlGeography type represents data in a geodetic (round earth) coordinate system.
	SqlGeographyBuilder	Constructs instances of SqlGeography objects by using IGeographySink interface.
	SqlGeometry	The SqlGeometry type represents data in a Euclidean (flat) coordinate system.
	SqlGeometryBuilder	Constructs instances of SqlGeometry objects by using IGeometrySink interface.

	结构	说明
	SqlHierarchyId	The SqlHierarchyId type represents a position in a hierarchical structure, specifying depth and breadth.

接口

	接口	说明
	IGeographySink	已过时。Interface used by SqlGeographyBuilder to construct a SqlGeography object. This API is obsolete. IGeographySink110 should be used instead.
	IGeographySink110	Defines the interface used by SqlGeographyBuilder to construct a SqlGeography object.
	IGeometrySink	已过时。Defines the interface that the SqlGeometryBuilder class uses to construct a SqlGeometryBuilder object. This API is obsolete. IGeometrySink110 should be used instead.
	IGeometrySink110	Defines the interface used by SqlGeometryBuilder to construct a SqlGeometry object.
	ISqlSpatialGridIndexable	基础结构。Defines the interface that is implemented by SqlGeography and SqlGeometry type objects to support spatial indexing.

枚举

	枚举	说明
	OpenGisGeographyType	Lists supported and extended Open GIS geography types.
	OpenGisGeometryType	Lists Open GIS geometry types.
