SqlGeometry.InstanceOf Method
Tests if the SqlGeometry instance is the same as the specified type.
Namespace: Microsoft.SqlServer.Types
Assembly: Microsoft.SqlServer.Types (in Microsoft.SqlServer.Types.dll)
Syntax
'Declaration

'Usage
Dim instance As SqlGeometry
Dim geometryType As String
Dim returnValue As SqlBoolean

member InstanceOf :
geometryType:string -> SqlBoolean
public function InstanceOf(
geometryType : String
) : SqlBoolean
Parameters
- geometryType
Type: System.String
Specifies the type of geometry that the calling SqlGeometry will be compared to.
Return Value
Type: System.Data.SqlTypes.SqlBoolean
A SqlBoolean value indicating if the calling SqlGeometry is of the specified geometry type. Returns true if the type of a SqlGeometry instance is the same as the specified type, or if the specified type is an ancestor of the instance type. Otherwise, returns false.
Remarks
The input for the method must be one of the following: Geometry, Point, Curve, LineString, Surface, Polygon, GeometryCollection, MultiSurface, MultiPolygon, MultiCurve, MultiLineString, and MultiPoint. This method throws an ArgumentException if any other strings are used for the input.
