You can use the CalculateStrokeLength method to determine the stroke length of the following vector items:
The following code computes a selected map item’s stroke length when the MapControl.SelectionChanged event occurs:
private void MapControl_SelectionChanged(object sender, MapItemSelectionChangedEventArgs e) {
MapShape mapShape = vectorLayer.SelectedItems[0] as MapShape;
double strokeLength = GeoUtils.CalculateStrokeLength(mapShape);
label.Content = $"StokeLength: {strokeLength / 1000:F2} km";
}
Private Sub MapControl_SelectionChanged(ByVal sender As Object, ByVal e As MapItemSelectionChangedEventArgs)
Dim mapShape As MapShape = CType(vectorLayer.SelectedItems(0),MapShape)
Dim strokeLength As Double = GeoUtils.CalculateStrokeLength(mapShape)
label.Content = "StokeLength: {strokeLength / 1000:F2} km"
End Sub
