SqlGeometry.STIsRing Method

Determines whether the calling SqlGeometry instance is a ring.

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

Syntax

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

returnValue = instance.STIsRing()

[SqlMethodAttribute(IsDeterministic = true, IsPrecise = false)]
public SqlBoolean STIsRing()

[SqlMethodAttribute(IsDeterministic = true, IsPrecise = false)]
public:
SqlBoolean STIsRing()

[<SqlMethodAttribute(IsDeterministic = true, IsPrecise = false)>]
member STIsRing : unit -> SqlBoolean

public function STIsRing() : SqlBoolean

Return Value

Type: System.Data.SqlTypes.SqlBoolean

Returns true if a geometry instance fulfills the following requirements:

• It is a LineString instance.

• It is closed.

• It is simple.

Returns false if the LineString instance does not meet the requirements.

Remarks

For a SqlGeometry instance to be closed and simple, both STIsClosed and STIsSimple must return true when invoked on the instance. To determine the instance type of a SqlGeometry, use STGeometryType.
