SqlGeometryBuilder Class

Constructs instances of SqlGeometry objects by using IGeometrySink interface.

Object
  Microsoft.SqlServer.Types.SqlGeometryBuilder

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

public class SqlGeometryBuilder implements IGeometrySink110, IGeometrySink

The SqlGeometryBuilder type exposes the following members.

  NameDescription

  NameDescription
Public methodAddCircularArc(Double, Double, Double, Double)Adds a circular arc to the path.
Public methodAddCircularArc(Double, Double, Nullable(Double), Nullable(Double), Double, Double, Nullable(Double), Nullable(Double))Adds a circular arc to the path.
Public methodAddLine(Double, Double)Constructs additional points in a geometry type figure.
Public methodAddLine(Double, Double, Nullable(Double), Nullable(Double))Constructs additional points in the call sequence for a geometry type.
Public methodBeginFigure(Double, Double)Starts the call sequence for a geometry figure.
Public methodBeginFigure(Double, Double, Nullable(Double), Nullable(Double))Starts the call sequence for a geometry figure.
Public methodBeginGeometryInitializes a call sequence for a geometry type.
Public methodEndFigureFinishes a call sequence for a geometry figure.
Public methodEndGeometryFinishes a call sequence for a geometry type.
Public methodEquals (Inherited from Object.)
Protected methodFinalize (Inherited from Object.)
Public methodGetHashCode (Inherited from Object.)
Public methodGetType (Inherited from Object.)
Protected methodMemberwiseClone (Inherited from Object.)
Public methodSetSridSets the Spatial Reference Identifier (SRID) for a geometry type call sequence.
Public methodToString (Inherited from Object.)

Throws FormatException for an invalid call sequence or when a call sequence is incomplete when ConstructedGeometry() is invoked.

The following example constructs a SqlGeometry object from a MultiLineString.

SqlGeometryBuilder b = new SqlGeometryBuilder();

b.SetSrid(0);

b.BeginGeometry(OpenGisGeometryType.MultiLineString);

b.BeginGeometry(OpenGisGeometryType.LineString);

b.BeginFigure(1, 1);

b.AddLine(3, 4);

b.EndFigure();

b.EndGeometry();

b.BeginGeometry(OpenGisGeometryType.LineString);

b.BeginFigure(-5, -3);

b.AddLine(2, 2);

b.EndFigure();

b.EndGeometry();

b.EndGeometry();

SqlGeometry g = b.ConstructedGeometry();

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
