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