Menghitung jarak antara titik terdekat dalam dua nilai.

Overload

Distance(DbGeography, DbGeography)	Menghitung jarak antara titik terdekat dalam dua DbGeography nilai.
Distance(DbGeometry, DbGeometry)	Menghitung jarak antara titik terdekat dalam dua DbGeometry nilai.

Distance(DbGeography, DbGeography)

Menghitung jarak antara titik terdekat dalam dua DbGeography nilai.

public:
 abstract double Distance(System::Data::Spatial::DbGeography ^ geographyValue, System::Data::Spatial::DbGeography ^ otherGeography);

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

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

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

Parameter

geographyValue

DbGeography

Nilai geografi pertama.

otherGeography

DbGeography

Nilai geografi kedua.

Mengembalikan

Double

Nilai ganda yang menentukan jarak antara dua titik terdekat dalam geographyValue dan otherGeography.

Pengecualian

ArgumentNullException

geographyValue otherGeography

ArgumentException

geographyValue otherGeography

Distance(DbGeometry, DbGeometry)

Menghitung jarak antara titik terdekat dalam dua DbGeometry nilai.

public:
 abstract double Distance(System::Data::Spatial::DbGeometry ^ geometryValue, System::Data::Spatial::DbGeometry ^ otherGeometry);

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

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

otherGeometry

DbGeometry

Nilai geometri kedua.

Mengembalikan

Double

Nilai ganda yang menentukan jarak antara dua titik terdekat dalam geometryValue dan otherGeometry.

Pengecualian

ArgumentNullException
