所以，我的问题是:
如何在 Windows Phone 8.1 通用应用中获取街道地址的地理位置?

我在 this stackoverflow answer 中找到了解决方案，但是，它适用于旧的 Silverlight 应用程序，而不是新的 Universal Store我目前使用的应用 API.

I found a solution in this stackoverflow answer, however, it's for the old Silverlight apps and not the new Universal Store app APIs that I'm currently using.

推荐答案

这里是获取地理位置和启动默认地图路线的代码

Here is the code to get geolocation and also to launch the default map for directions

这里是 MSDN 链接

    // Nearby location to use as a query hint.
BasicGeoposition queryHint = new BasicGeoposition();
    // DALLAS
queryHint.Latitude = 32.7758;
queryHint.Longitude = -96.7967;

Geopoint hintPoint = new Geopoint(queryHint);

MapLocationFinderResult result = await MapLocationFinder.FindLocationsAsync(
                        "street, city, state zip",
                        hintPoint,
                        3);

if (result.Status == MapLocationFinderStatus.Success)
{
    if (result.Locations != null && result.Locations.Count > 0)
    {
        Uri uri = new Uri("ms-drive-to:?destination.latitude=" + result.Locations[0].Point.Position.Latitude.ToString() +
            "&destination.longitude=" + result.Locations[0].Point.Position.Longitude.ToString() + "&destination.name=" + "myhome");

        var success = await Windows.System.Launcher.LaunchUriAsync(uri);
    }
}
