windows-phone-8 - 使用 NuGet 将 lat long 转换为地址

Question

我正在开发一个 windows phone 应用程序，它需要将当前的纬度和经度转换为地图上的地址。如何使用 GoogleMaps.LocationServices Nu Get 包将地理坐标转换为指向地图的地址。

Answer 1

GoogleMaps.LocationServices NuGet 包没有查找街道地址的方法。试试下面的代码。

const string API_ADDRESS_FROM_LATLONG = "http://maps.googleapis.com/maps/api/geocode/xml?latlng={0},{1}&sensor=false";

public void GetAddressFromLatLong(string Lat, string Long)
{
    try 
    {           
        var webClient = new WebClient();
        webClient.DownloadStringAsync(new Uri(string.Format(API_ADDRESS_FROM_LATLONG, Lat, Long)));
        webClient.DownloadStringCompleted += webClient_DownloadStringCompleted;
    }
    catch (Exception)
    {
    }
}

void webClient_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e)
{
    try
    {
        XDocument doc = XDocument.Parse(e.Result);
        var Address = doc.Descendants("result").FirstOrDefault().Descendants("formatted_address").FirstOrDefault().Value;
        MessageBox.Show(Address);
    }
    catch (Exception)
    {
    }
}
