SqlGeography.STGeomCollFromWKB 方法

Returns a GeometryCollection 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 STGeomCollFromWKB ( _
    wkbGeometryCollection As SqlBytes, _
    srid As Integer _
) As SqlGeography
用法
Dim wkbGeometryCollection As SqlBytes 
Dim srid As Integer 
Dim returnValue As SqlGeography 

returnValue = SqlGeography.STGeomCollFromWKB(wkbGeometryCollection, _
    srid)

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

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

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

public static function STGeomCollFromWKB(
    wkbGeometryCollection : SqlBytes, 
    srid : int
) : SqlGeography

参数

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

• srid
  类型：System.Int32
  An int expression representing the spatial reference ID (SRID) of the GeometryCollection instance you wish to return.

返回值

类型：Microsoft.SqlServer.Types.SqlGeography
A SqlGeography value constructed from the specified WKB geometry collection.

注释

The OGC type of the SqlGeography instance returned by STGeomCollFromWKB is set to GeometryCollection, MultiPolygon, MultiLineString, or MultiPoint, depending on the corresponding WKB input.

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