SqlGeography.STIsClosed Method
Determines whether the calling SqlGeography instance is closed.
Namespace: Microsoft.SqlServer.Types
Assembly: Microsoft.SqlServer.Types (in Microsoft.SqlServer.Types.dll)
Syntax
'Declaration
<SqlMethodAttribute(IsDeterministic := True, IsPrecise := False)> _
Public Function STIsClosed As SqlBoolean
'Usage
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
Return Value
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.
Remarks
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.
