    private void simpleButton1_Click(object sender, EventArgs e) {
        double distance = GeoUtils.CalculateDistance(new GeoPoint(-5.93107, -35.112723), new GeoPoint(4.253438, 5.47072), true);
    }

VB.NET

Imports DevExpress.XtraMap
'...
    Private Sub simpleButton1_Click(ByVal sender As Object, ByVal e As EventArgs)
        Dim distance As Double = GeoUtils.CalculateDistance(New GeoPoint(-5.93107, -35.112723), New GeoPoint(4.253438, 5.47072), True)
    End Sub
