How to load the latitude and longitude pairs to a C# object and work them?

Question

Good night! I’m developing a web page where the user can plot a route. I use the google maps api. I need to take the latitude and longitude pairs of the route, press for an object c# and, after working the latitude and longitude information, return the lat. e long. for google maps to color the route according to the information I will return. For example: when I return latitude: -12.123, longitude: 13.123 I need it to be colored according to a weight I will pass. For example, if the weight is less than 5, then color yellow, greater than 5, blue. I will post my code that generates the route for who knows you help me.

<script type="text/javascript" src="http://maps.googleapis.com/maps/api/js?sensor=false"></script>
<script language="javascript" type="text/javascript">
    var directionsDisplay;
    var directionsService = new google.maps.DirectionsService();

    function InitializeMap() {
        directionsDisplay = new google.maps.DirectionsRenderer();
        var latlng = new google.maps.LatLng(-19.9412735, -44.07623219999999);
        var myOptions =
    {
        zoom: 16,
        center: latlng,
        mapTypeId: google.maps.MapTypeId.ROADMAP
    };
        var map = new google.maps.Map(document.getElementById("map"), myOptions);

        directionsDisplay.setMap(map);
        directionsDisplay.setPanel(document.getElementById('directionpanel'));

        var control = document.getElementById('control');
        control.style.display = 'block';
    }

    function calcRoute() {
        var start = document.getElementById('startvalue').value;
        var end = document.getElementById('endvalue').value;
        var request = {
            origin: start,
            destination: end,
            travelMode: google.maps.DirectionsTravelMode.DRIVING
        };
        directionsService.route(request, function (response, status) {
            if (status == google.maps.DirectionsStatus.OK) {
                directionsDisplay.setDirections(response);
            }
        });
    }
    function Button1_onclick() {
        calcRoute();
    }
    window.onload = InitializeMap;
</script>

There is the geocoordinate object in System.Device.Location which serves precisely to work with coordinates.

He has the methods Latitude and Longitude.
