SqlGeometry.STDistance-Methode

Returns the shortest distance between a point in a SqlGeometry instance and a point in the specified SqlGeometry instance.

Namespace:  Microsoft.SqlServer.Types
Assembly:  Microsoft.SqlServer.Types (in Microsoft.SqlServer.Types.dll)

Syntax

'Declaration
<SqlMethodAttribute(IsDeterministic := True, IsPrecise := False)> _
Public Function STDistance ( _
    other As SqlGeometry _
) As SqlDouble
'Usage
Dim instance As SqlGeometry 
Dim other As SqlGeometry 
Dim returnValue As SqlDouble 

returnValue = instance.STDistance(other)

[SqlMethodAttribute(IsDeterministic = true, IsPrecise = false)]
public SqlDouble STDistance(
    SqlGeometry other
)

[SqlMethodAttribute(IsDeterministic = true, IsPrecise = false)]
public:
SqlDouble STDistance(
    SqlGeometry^ other
)

[<SqlMethodAttribute(IsDeterministic = true, IsPrecise = false)>]
member STDistance : 
        other:SqlGeometry -> SqlDouble

public function STDistance(
    other : SqlGeometry
) : SqlDouble

Parameter

• other
  Typ: Microsoft.SqlServer.Types.SqlGeometry
  The SqlGeometry instance from which to measure the distance between the instance on which STDistance is invoked. If other is an empty set, STDistance returns null.

Rückgabewert

Typ: System.Data.SqlTypes.SqlDouble
A SqlDouble value that represents the shortest distance between a point in the calling SqlGeometry and a point in the specified SqlGeometry.

Hinweise

STDistance always returns null if the spatial reference IDs (SRIDs) of the SqlGeometry instances do not match.
