Initializes a call sequence for a geometry type.

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

Syntax

public virtual void BeginGeometry(
    OpenGisGeometryType type
)

public:
virtual void BeginGeometry(
    OpenGisGeometryType type
)

abstract BeginGeometry : 
        type:OpenGisGeometryType -> unit
override BeginGeometry : 
        type:OpenGisGeometryType -> unit

Public Overridable Sub BeginGeometry (
    type As OpenGisGeometryType
)

Parameters

type
Type: Microsoft.SqlServer.Types.OpenGisGeometryType

OpenGisGeometryType object that indicates the type being created by the call sequence.

Implements

IGeometrySink.BeginGeometry(OpenGisGeometryType)

Remarks

Call sequences that open with a BeginGeometry() must close with a EndGeometry().

BeginGeometry() and EndGeometry() pairs can be nested.

Valid values for type are Point, MultiPoint, LineString, MultiLineString, Polygon, MultiPolygon, and GeometryCollection.

The following example is a WKI (Well Known Interface) call sequence for a MultiLineString object.

BeginGeometry MultiLineString

BeginGeometry LineString

BeginFigure 1 0

AddLine 2 0

EndFigure

EndGeometry

BeginGeometry LineString
