DbGeography.PointFromBinary(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 DbGeography 点值。

public:
 static System::Data::Spatial::DbGeography ^ PointFromBinary(cli::array <System::Byte> ^ pointWellKnownBinary, int coordinateSystemId);
public static System.Data.Spatial.DbGeography PointFromBinary (byte[] pointWellKnownBinary, int coordinateSystemId);
static member PointFromBinary : byte[] * int -> System.Data.Spatial.DbGeography
Public Shared Function PointFromBinary (pointWellKnownBinary As Byte(), coordinateSystemId As Integer) As DbGeography

参数

pointWellKnownBinary
Byte[]

包含地理值的知名二进制表示形式的字节数组。

coordinateSystemId
Int32

新 DbGeography 值应使用的坐标系的标识符。

返回

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

例外

pointWellKnownBinary

coordinateSystemId
