DbSpatialServices.GeometryFromText Method

Definition

Namespace:

System.Data.Spatial

Assembly:

System.Data.Entity.dll

Creates a new DbGeometry value based on the specified well-known text value.

Overloads

GeometryFromText(String)	Creates a new DbGeometry value based on the specified well-known text value.
GeometryFromText(String, Int32)	Creates a new DbGeometry value based on the specified well-known text value and coordinate system identifier (SRID).

GeometryFromText(String)

Creates a new DbGeometry value based on the specified well-known text value.

public:
 abstract System::Data::Spatial::DbGeometry ^ GeometryFromText(System::String ^ wellKnownText);

public abstract System.Data.Spatial.DbGeometry GeometryFromText (string wellKnownText);

abstract member GeometryFromText : string -> System.Data.Spatial.DbGeometry

Public MustOverride Function GeometryFromText (wellKnownText As String) As DbGeometry

Parameters

wellKnownText

String

A string that contains a well-known text representation of the geometry value.

Returns

DbGeometry

A new DbGeometry value as defined by the well-known text value with the default DbGeometry coordinate system identifier (SRID) (DefaultCoordinateSystemId).

Exceptions

ArgumentNullException

wellKnownText

GeometryFromText(String, Int32)

Creates a new DbGeometry value based on the specified well-known text value and coordinate system identifier (SRID).

public:
 abstract System::Data::Spatial::DbGeometry ^ GeometryFromText(System::String ^ wellKnownText, int coordinateSystemId);

public abstract System.Data.Spatial.DbGeometry GeometryFromText (string wellKnownText, int coordinateSystemId);

abstract member GeometryFromText : string * int -> System.Data.Spatial.DbGeometry

Public MustOverride Function GeometryFromText (wellKnownText As String, coordinateSystemId As Integer) As DbGeometry

Parameters

wellKnownText

String

A string that contains a well-known text representation of the geometry value.

coordinateSystemId

Int32

The identifier of the coordinate system that the new DbGeometry value should use.

Returns

DbGeometry

A new DbGeometry value as defined by the well-known text value with the specified coordinate system identifier (SRID) (DefaultCoordinateSystemId).

Exceptions

ArgumentNullException

wellKnownText

ArgumentException

coordinateSystemId
