Copy
// Create a four sided polygon in Los Angeles, Ca.
Telogis.GeoBase.Geometry.Polygon myPolygon = new Telogis.GeoBase.Geometry.Polygon(
    new Telogis.GeoBase.Geometry.LineString[] {
        new Telogis.GeoBase.Geometry.LineString(
        new LatLon(33.694165,-117.956236),

        new LatLon(33.694165,-117.956236))

// Create a Line that crosses over the polygon
Telogis.GeoBase.Geometry.LineString newLine = new Telogis.GeoBase.Geometry.LineString(
    new Telogis.GeoBase.LatLon[] {
            new Telogis.GeoBase.LatLon(33.671409,-117.969853),
            new Telogis.GeoBase.LatLon(33.585837,-117.781247)}

// Use the Intersects method to test whether the polygon contains, intersects or touches the line
Console.WriteLine("Do the polygon and line intersect? {0}", myPolygon.Intersects(newLine.Points));
// 'Do the polygon and line intersect? True'
