Parametri

• geometryCollectionTaggedText
  Tipo: System.Data.SqlTypes.SqlChars
  The WKT representation of the SqlGeometry instance you wish to return.

• srid
  Tipo: System.Int32
  An integer expression that represents the spatial reference ID (SRID) of the SqlGeometry instance you wish to return.

Valore restituito

Tipo: Microsoft.SqlServer.Types.SqlGeometry
A SqlGeometry value constructed from the specified WKT representation.

Osservazioni

The OGC type of the SqlGeometry instance returned by STGeomCollFromText is set to the corresponding WKT input.

This method will throw an exception if the input is not valid.

This member is static.
