DbSpatialServices.GeographyPolygonFromBinary(Byte[], Int32) 方法

定义

命名空间:

System.Data.Spatial

程序集:

System.Data.Entity.dll

创建基于指定已知二进制值和坐标系统标识符 (SRID) 的新 DbGeography 多多边形值。

public:
 abstract System::Data::Spatial::DbGeography ^ GeographyPolygonFromBinary(cli::array <System::Byte> ^ polygonWellKnownBinary, int coordinateSystemId);

public abstract System.Data.Spatial.DbGeography GeographyPolygonFromBinary (byte[] polygonWellKnownBinary, int coordinateSystemId);

abstract member GeographyPolygonFromBinary : byte[] * int -> System.Data.Spatial.DbGeography

Public MustOverride Function GeographyPolygonFromBinary (polygonWellKnownBinary As Byte(), coordinateSystemId As Integer) As DbGeography

参数

polygonWellKnownBinary

Byte[]

包含地理值的知名二进制表示形式的字节数组。

coordinateSystemId

Int32

新建 DbGeography 值应使用的坐标系的标识符。

返回

DbGeography

通过指定坐标系统标识符 (SRID) 由知名二进制值定义的新的 DbGeography 值 DefaultCoordinateSystemId。

例外

ArgumentNullException

polygonWellKnownBinary

ArgumentException

coordinateSystemId
