Parámetros

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

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

Valor devuelto

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

Comentarios

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

This method will throw a FormatException if the input is not well-formatted.

This member is static.
