方法一：js

<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script>
<script type="text/javascript">
var geocoder;
var map;
function initialize() {

var latlng =new google.maps.LatLng(31.23, 121.47);

<body onload="initialize()">
<div>
<input id="address" type="text" value="上海市">
<input type="button" value="地址解析" onclick="codeAddress()">

<div id="map_canvas" style="height:90%;top:30px"></div>
</body>
</html>
方法二：c#
Geo g = new Geo("地址");然后g.Latitude和g.Longtitude就是输入地址的纬度和经度
