The following code computes the distance between two points:

C#

using DevExpress.Xpf.Map;

private void OnButtonClick(object sender, RoutedEventArgs e) {
    double distance = GeoUtils.CalculateDistance(new GeoPoint(-5.93107, -35.112723), new GeoPoint(4.253438, 5.47072), true);
}

VB.NET

Imports DevExpress.Xpf.Map

Private Sub OnButtonClick(ByVal sender As Object, ByVal e As RoutedEventArgs)
    Dim distance As Double = GeoUtils.CalculateDistance(New GeoPoint(-5.93107, -35.112723), New GeoPoint(4.253438, 5.47072), True)
End Sub
