Méthode STIsClosed

Determines whether the calling SqlGeography instance is closed.

Espace de noms :  Microsoft.SqlServer.Types
Assembly :  Microsoft.SqlServer.Types (en Microsoft.SqlServer.Types.dll)

Syntaxe

'Déclaration
<SqlMethodAttribute(IsDeterministic := True, IsPrecise := False)> _
Public Function STIsClosed As SqlBoolean
'Utilisation
Dim instance As SqlGeography
Dim returnValue As SqlBoolean

returnValue = instance.STIsClosed()
[SqlMethodAttribute(IsDeterministic = true, IsPrecise = false)]
public SqlBoolean STIsClosed()
[SqlMethodAttribute(IsDeterministic = true, IsPrecise = false)]
public:
SqlBoolean STIsClosed()
[<SqlMethodAttribute(IsDeterministic = true, IsPrecise = false)>]
member STIsClosed : unit -> SqlBoolean 
public function STIsClosed() : SqlBoolean

Valeur de retour

Type : System.Data.SqlTypes. . :: . .SqlBoolean
A SqlBoolean value indicating whether the start and end points of the SqlGeography instance are the same. Returns true if both points are the same. Otherwise, false.

Notes

This method returns false if any figures of a geography instance are points, or if the instance is empty.

This method returns true for geography collection types if each contained SqlGeography instance is closed.

All Polygon instances are considered closed.
