DbSpatialServices.GeometryPolygonFromBinary(Byte[], Int32) 方法

定义

创建基于指定已知二进制值和坐标系统标识符 (SRID) 的新 DbGeometry 多多边形值。Creates a new DbGeometry polygon value based on the specified well-known binary value and coordinate system identifier (SRID).

public:
 abstract System::Data::Spatial::DbGeometry ^ GeometryPolygonFromBinary(cli::array <System::Byte> ^ polygonWellKnownBinary, int coordinateSystemId);
public abstract System.Data.Spatial.DbGeometry GeometryPolygonFromBinary (byte[] polygonWellKnownBinary, int coordinateSystemId);
abstract member GeometryPolygonFromBinary : byte[] * int -> System.Data.Spatial.DbGeometry
Public MustOverride Function GeometryPolygonFromBinary (polygonWellKnownBinary As Byte(), coordinateSystemId As Integer) As DbGeometry

参数

polygonWellKnownBinary
Byte[]

包含几何值的知名二进制表示形式的字节数组。A byte array that contains a well-known binary representation of the geometry value.

coordinateSystemId
Int32

新建 DbGeometry 值应使用的坐标系的标识符。The identifier of the coordinate system that the new DbGeometry value should use.

返回

DbGeometry

通过指定坐标系统标识符 (SRID) 由知名二进制值定义的新的 DbGeometryDefaultCoordinateSystemIdA new DbGeometry value as defined by the well-known binary value with the specified coordinate system identifier (SRID) (DefaultCoordinateSystemId).

例外
