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的新 DbGeography 值。

重载

GeographyFromBinary(Byte[], Int32)	创建基于指定已知二进制值和坐标系统标识符 (SRID) 的新 DbGeography 值。
GeographyFromBinary(Byte[])	创建基于指定已知二进制值的新 DbGeography 值。

GeographyFromBinary(Byte[], Int32)

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

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

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

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

Public MustOverride Function GeographyFromBinary (wellKnownBinary As Byte(), coordinateSystemId As Integer) As DbGeography

参数

wellKnownBinary

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

wellKnownBinary

ArgumentException

coordinateSystemId

GeographyFromBinary(Byte[])

创建基于指定已知二进制值的新 DbGeography 值。

public:
 abstract System::Data::Spatial::DbGeography ^ GeographyFromBinary(cli::array <System::Byte> ^ wellKnownBinary);

public abstract System.Data.Spatial.DbGeography GeographyFromBinary (byte[] wellKnownBinary);

abstract member GeographyFromBinary : byte[] -> System.Data.Spatial.DbGeography

Public MustOverride Function GeographyFromBinary (wellKnownBinary As Byte()) As DbGeography

参数

wellKnownBinary

Byte[]

包含地理值的知名二进制表示形式的字节数组。

返回

DbGeography

通过默认的 DbGeography 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
