SqlGeography.STGeomFromWKB 方法

Returns a SqlGeography instance from an Open Geospatial Consortium (OGC) Well-Known Binary (WKB) representation.

命名空间：  Microsoft.SqlServer.Types
程序集：  Microsoft.SqlServer.Types（在 Microsoft.SqlServer.Types.dll 中）

语法

声明
<SqlMethodAttribute(IsDeterministic := True, IsPrecise := True)> _
Public Shared Function STGeomFromWKB ( _
    wkbGeometry As SqlBytes, _
    srid As Integer _
) As SqlGeography
用法
Dim wkbGeometry As SqlBytes 
Dim srid As Integer 
Dim returnValue As SqlGeography 

returnValue = SqlGeography.STGeomFromWKB(wkbGeometry, _
    srid)

[SqlMethodAttribute(IsDeterministic = true, IsPrecise = true)]
public static SqlGeography STGeomFromWKB(
    SqlBytes wkbGeometry,
    int srid
)

[SqlMethodAttribute(IsDeterministic = true, IsPrecise = true)]
public:
static SqlGeography^ STGeomFromWKB(
    SqlBytes^ wkbGeometry, 
    int srid
)

[<SqlMethodAttribute(IsDeterministic = true, IsPrecise = true)>]
static member STGeomFromWKB : 
        wkbGeometry:SqlBytes * 
        srid:int -> SqlGeography

public static function STGeomFromWKB(
    wkbGeometry : SqlBytes, 
    srid : int
) : SqlGeography

参数

• wkbGeometry
  类型：System.Data.SqlTypes.SqlBytes
  The WKB representation of the SqlGeography instance you wish to return.

• srid
  类型：System.Int32
  An int expression that represents the Spatial Reference ID (SRID) of the SqlGeography instance you wish to return.

返回值

类型：Microsoft.SqlServer.Types.SqlGeography
A SqlGeography instance constructed from the specified WKB representation.

注释

The OGC type of the SqlGeography instance returned by the STGeomFromText method is set to the corresponding WKB input.

This method throws a FormatException if the input is not well-formatted.
