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

Syntax

'Declaration
<SqlMethodAttribute(IsDeterministic := True, IsPrecise := True)> _
Public Function RingN ( _
    n As Integer _
) As SqlGeography
'Usage
Dim instance As SqlGeography
Dim n As Integer
Dim returnValue As SqlGeography

returnValue = instance.RingN(n)

[SqlMethodAttribute(IsDeterministic = true, IsPrecise = true)]
public SqlGeography RingN(
    int n
)

[SqlMethodAttribute(IsDeterministic = true, IsPrecise = true)]
public:
SqlGeography^ RingN(
    int n
)

[<SqlMethodAttribute(IsDeterministic = true, IsPrecise = true)>]
member RingN : 
        n:int -> SqlGeography

public function RingN(
    n : int
) : SqlGeography

Parameters

• n
  Type: System.Int32
  An int expression between 1 and the number of rings in a polygon instance.

Return Value

Type: Microsoft.SqlServer.Types.SqlGeography
A SqlGeography object that represents the ring specified by n.

Remarks

If the value of the ring index n is less than 1, this method throws an ArgumentOutOfRangeException. The ring index value must be greater than or equal to 1 and should be less than or equal to the number returned by NumRings.
