Параметры

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

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

Возвращаемое значение

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

Замечания

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.
