Parametri

Valore restituito

Tipo: Microsoft.SqlServer.Types. . :: . .SqlGeometry
A SqlGeometry object that represents the unique points in the calling SqlGeometry.

Osservazioni

This method always returns null Nothing nullptr unit riferimento Null (Nothing in Visual Basic). if the spatial reference IDs (SRIDs) of the SqlGeometry instances do not match.
