Parámetros

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

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

Valor devuelto

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

Comentarios

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.
