備註

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

範例

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();
