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::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

Parameters
