SqlGeometryBuilder.BeginGeometry-Methode

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
)

Parameter

• type
  Typ: Microsoft.SqlServer.Types.OpenGisGeometryType
  OpenGisGeometryType object that indicates the type being created by the call sequence.

Implementiert

IGeometrySink.BeginGeometry(OpenGisGeometryType)

Hinweise

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.
