Definition

Namespace:

System.Data.Entity.Spatial

Assembly:

EntityFramework.dll

Overloads

Distance(DbGeography, DbGeography)	Computes the distance between the closest points in two DbGeography values.
Distance(DbGeometry, DbGeometry)	Computes the distance between the closest points in two DbGeometry values.

Distance(DbGeography, DbGeography)

Computes the distance between the closest points in two DbGeography values.

public abstract double Distance (System.Data.Entity.Spatial.DbGeography geographyValue, System.Data.Entity.Spatial.DbGeography otherGeography);

abstract member Distance : System.Data.Entity.Spatial.DbGeography * System.Data.Entity.Spatial.DbGeography -> double

Public MustOverride Function Distance (geographyValue As DbGeography, otherGeography As DbGeography) As Double

Parameters

geographyValue

DbGeography

The first geography value.

otherGeography

DbGeography

The second geography value.

Returns

Double

A double value that specifies the distance between the two closest points in geographyValue and otherGeography.

Exceptions

ArgumentNullException

geographyValue or otherGeography is null.

ArgumentException

geographyValue or otherGeography is not compatible with this spatial services implementation.

Distance(DbGeometry, DbGeometry)

Computes the distance between the closest points in two DbGeometry values.

public abstract double Distance (System.Data.Entity.Spatial.DbGeometry geometryValue, System.Data.Entity.Spatial.DbGeometry otherGeometry);

abstract member Distance : System.Data.Entity.Spatial.DbGeometry * System.Data.Entity.Spatial.DbGeometry -> double

Public MustOverride Function Distance (geometryValue As DbGeometry, otherGeometry As DbGeometry) As Double

Parameters

geometryValue

DbGeometry

The first geometry value.

otherGeometry

DbGeometry

The second geometry value.

Returns

Double

A double value that specifies the distance between the two closest points in geometryValue and otherGeometry.

Exceptions

ArgumentNullException

geometryValue or otherGeometry is null.

ArgumentException

geometryValue or otherGeometry is not compatible with this spatial services implementation.
