SqlGeography.RingN Method
Returns the specified ring of the SqlGeography instance: 1 ≤ n ≤ NumRings().
Namespace: Microsoft.SqlServer.Types
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)>]
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.
