Beispiele
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();
