Параметры

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

Возвращаемое значение

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

Замечания

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.
