C#

MapRuler ruler = mapControl1.Measurements.CreateRuler(RulerType.Distance, 
                                                       new List<CoordPoint>() {
                                                           new GeoPoint(48.864716, 2.349014), // Paris
                                                           new GeoPoint(45.46427, 9.18951),   // Milan
                                                           new GeoPoint(48.20849, 16.37208)   // Vienna
                                                       });
double distance = ruler.Measurement;

VB.NET

Dim ruler As MapRuler = mapControl1.Measurements.CreateRuler(RulerType.Distance, New List(Of CoordPoint)() From {
       New GeoPoint(48.864716, 2.349014), ' Paris
New GeoPoint(45.46427, 9.18951),   ' Milan
New GeoPoint(48.20849, 16.37208)   ' Vienna
})
Dim distance As Double = ruler.Measurement
