Send (Pass) values from Code Behind to JavaScript for populaing Google Maps markers in ASP.Net

In need of desperate help. Is there any way of doing this by just using asp.net, c# and javascript. I dont wanna use visual basic if possible. My database table contains id, address, lat and lng.

I need x1 to be address, x2 to be lat and x3 to be lng.

And what should i do for the back end part(the aspx.cs)?

i searched and tried a lot of things but none seem to work

var locations = [
                   { title: x1, location: { lat: x2, lng: x3 } }
                ];

//create an array of markers
for (var i = 0; i < locations.length; i++) {
    //get position from array
    var position = locations[i].location;
    var title = locations[i].title;

    //create markers for each location & put into array
    var marker = new google.maps.Marker({
    //map: map, //here 2
    position: position,
    title: title,
    animation: google.maps.Animation.DROP,
    id: i
});
}
