C#: Creation of a Google Map with a line?
after three days of trying I'm near givin开发者_运维百科g it up.. I try to use the Google Maps API to create a map with a longer line formed by several points. Unfortunately not even uploading a XML file worked out for me (Though I successfully authorized myself with my Google account).
Can someone please give me help and post a C#/VB code (snippet) on how to create a map and draw a line on it? Thanks for you help!

If you use javascript API for Google map, here is a sample:
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="initial-scale=1.0, user-scalable=no" />
<meta http-equiv="content-type" content="text/html; charset=UTF-8"/>
<title>Google Maps JavaScript API v3 Example: Polyline Simple</title>
<link href="http://code.google.com/apis/maps/documentation/javascript/examples/default.css" rel="stylesheet" type="text/css" />
<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script>
<script type="text/javascript">
function initialize() {
var myLatLng = new google.maps.LatLng(0, -180);
var myOptions = {
zoom: 3,
center: myLatLng,
mapTypeId: google.maps.MapTypeId.TERRAIN
};
var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
var flightPlanCoordinates = [
new google.maps.LatLng(37.772323, -122.214897),
new google.maps.LatLng(21.291982, -157.821856),
new google.maps.LatLng(-18.142599, 178.431),
new google.maps.LatLng(-27.46758, 153.027892)
];
var flightPath = new google.maps.Polyline({
path: flightPlanCoordinates,
strokeColor: "#FF0000",
strokeOpacity: 1.0,
strokeWeight: 2
});
flightPath.setMap(map);
}
</script>
</head>
<body onload="initialize()">
<div id="map_canvas"></div>
</body>
</html>
