SqlGeometryBuilder.BeginGeometry Method

Initializes a call sequence for a geometry type.

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

Syntax

'Declaration
Public Overridable Sub BeginGeometry ( _
    type As OpenGisGeometryType _
)
'Usage
Dim instance As SqlGeometryBuilder
Dim type As OpenGisGeometryType

instance.BeginGeometry(type)

public virtual void BeginGeometry(
    OpenGisGeometryType type
)

public:
virtual void BeginGeometry(
    OpenGisGeometryType type
)

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

public function BeginGeometry(
    type : OpenGisGeometryType
)

Parameters

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.
