Eu tenho o seguinte código para mostrar vários marcadores no gmap

<script type="text/javascript">

        function init() {
            var locations = [
              ['Bondi Beach', -33.890542, 151.274856, 4],
              ['Coogee Beach', -33.923036, 151.259052, 5],
              ['Cronulla Beach', -34.028249, 151.157507, 3],
              ['Manly Beach', -33.80010128657071, 151.28747820854187, 2],
              ['Maroubra Beach', -33.950198, 151.259302, 1]
            ];

            var map = new google.maps.Map(document.getElementById('map'), {
                zoom: 10,
                center: new google.maps.LatLng(-33.92, 151.25),
                mapTypeId: google.maps.MapTypeId.ROADMAP
            });

            var infowindow = new google.maps.InfoWindow();

            var marker, i;

            for (i = 0; i < locations.length; i++) {
                marker = new google.maps.Marker({
                    position: new google.maps.LatLng(locations[i][1], locations[i][2]),
                    map: map
                });

                google.maps.event.addListener(marker, 'click', (function (marker, i) {
                    return function () {
                        infowindow.setContent(locations[i][0]);
                        infowindow.open(map, marker);
                    }
                })(marker, i));
            }
            return false;
        }
    </script>

Eu quero fazer isso dinâmico, então eu tenho que passar isso

 var locations = [
              ['Bondi Beach', -33.890542, 151.274856, 4],
              ['Coogee Beach', -33.923036, 151.259052, 5],
              ['Cronulla Beach', -34.028249, 151.157507, 3],
              ['Manly Beach', -33.80010128657071, 151.28747820854187, 2],
              ['Maroubra Beach', -33.950198, 151.259302, 1]
            ];

de código c # para este js.

Eu tentei Hidden Field e este código

 List<String> oGeocodeList = new List<String>
                                         {
                                            "'Bondi Beach', -33.890542, 151.274856, 4",
                                            "'Coogee Beach', -33.923036, 151.259052, 5",
                                            "'Cronulla Beach', -34.028249, 151.157507, 3",
                                            "'Manly Beach', -33.80010128657071, 151.28747820854187, 2",
                                            "'Maroubra Beach', -33.950198, 151.259302, 1"
                                        };

        var geocodevalues = string.Join(",", oGeocodeList.ToArray());
        ClientScript.RegisterArrayDeclaration("locations", geocodevalues);

Mas sem sorte qualquer referência será útil para mim
