Overloads

PointAt(DbGeography, Int32)

Returns a point element of the given DbGeography value, if it represents a linestring or linear ring.
PointAt(DbGeometry, Int32)

Returns a point element of the given DbGeometry value, if it represents a linestring or linear ring.

PointAt(DbGeography, Int32)

Returns a point element of the given DbGeography value, if it represents a linestring or linear ring.

public abstract System.Data.Entity.Spatial.DbGeography PointAt (System.Data.Entity.Spatial.DbGeography geographyValue, int index);
abstract member PointAt : System.Data.Entity.Spatial.DbGeography * int -> System.Data.Entity.Spatial.DbGeography
Public MustOverride Function PointAt (geographyValue As DbGeography, index As Integer) As DbGeography

Parameters

geographyValue
DbGeography

The geography value, which need not represent a linestring or linear ring.

index
Int32

The position within the geography value from which the element should be taken.

Returns

DbGeography

The point in geographyValue at position index, if it represents a linestring or linear ring; otherwise null.

Exceptions

ArgumentNullException

geographyValue is null.

ArgumentException

geographyValue is not compatible with this spatial services implementation.

Applies to

Parameters

geometryValue
DbGeometry

The geometry value, which need not represent a linestring or linear ring.

index
Int32

The position within the geometry value from which the element should be taken.

Returns

DbGeometry

The point in geometryValue at position index, if it represents a linestring or linear ring; otherwise null.
