Ejemplos

The following example constructs a SqlGeometry object from a MultiLineString.

SqlGeographyBuilder b = new SqlGeographyBuilder();

b.SetSrid(4326);

b.BeginGeography(OpenGisGeographyType.MultiLineString);

b.BeginGeography(OpenGisGeographyType.LineString);

b.BeginFigure(-122.358, 47.653);

b.AddLine(-122.348, 47.649);

b.EndFigure();

b.EndGeography();

b.BeginGeography(OpenGisGeographyType.LineString);

b.BeginFigure(-118.481, 48.328);

b.AddLine(-119.002, 47.324);

b.EndFigure();

b.EndGeography();

b.EndGeography();

SqlGeography g = b.ConstructedGeography();
