从Windows窗体应用调用Google Maps API V3 Javascript API？

Question

Google推出了这款精美的全新Google Maps API v3,它是一款"Javascript API".

是否有可能从用Visual C#.net 3.5编写的Windows窗体应用程序中调用此API？

编辑:
目标是使用Google Maps Geocoder将地址转换为纬度/经常格式.

我想使用API​​的v3,因为它不再需要API密钥.API密钥应绑定到Web服务器,而Windows Forms应用程序则不然.

编辑:看起来不再需要api密钥.

您可以使用REST API并解析响应(XML/JSON/CSV).

http://maps.google.com/maps/geo?q=State+St,+Troy,+NY&output=csv&oe=utf8&sensor=false

输出:

200,6,42.730070,-73.690570

这是:

• 200 - G_GEO_SUCCESS
• 6 - 街道级精度
• 42.730070 - 纬度
• -73.690570 - 经度

如果您不熟悉System.Net API,它们将是这样的:

const string GeoCodeUrlFormat = "http://maps.google.com/maps/geo?q={0}&output=csv&oe=utf8&sensor=false";

string location = "State St, Troy, NY";
string url = String.Format(GeoCodeUrlFormat, HttpUtility.UrlEncode(location));

HttpRequest request = (HttpWebRequest)HttpWebRequest.Create(url);
HttpResponse response = (HttpResponse)request.GetResponse(); // Can throw an exception
Stream responseStream = response.GetResponseStream();

using (StreamReader reader = new StreamReader(responseStream)
{
    string firstLine = reader.ReadLine();

    string[] lineParts = firstLine.Split();

    GeolocationResult result = GoogleMapper.MapGeolocationResult(lineParts);

    // TADA
}

显然没有错误处理,它不支持多个返回值,我实际上没有实现MapGeolocationResult,但它应该给你一个开始.
