如何从纬度/经度坐标添加地图标记？ Windows 8 手机

Question

我已经从工具箱向应用程序添加了一个地图，但我试图弄清楚如何向地图添加一个标记，该标记将由按钮的单击事件触发。我知道如何获取设备的当前位置，如下所示。

但是我将如何添加到此以使用此位置数据在地图上绘制图钉/标记？有没有一种简单的方法可以使用从这段代码 sn-p 计算的 lat/lng 添加标记？

Geolocator geolocator = new Geolocator();
geolocator.DesiredAccuracyInMeters = 50;

try
{
    Geoposition geoposition = await geolocator.GetGeopositionAsync(
        maximumAge: TimeSpan.FromMinutes(5),
        timeout: TimeSpan.FromSeconds(10)
        );

    LatitudeTextBlock.Text = geoposition.Coordinate.Latitude.ToString("0.00");
    LongitudeTextBlock.Text = geoposition.Coordinate.Longitude.ToString("0.00");
}
catch (Exception ex)
{
    if ((uint)ex.HResult == 0x80004004)
    {
        // the application does not have the right capability or the location master switch is off
        StatusTextBlock.Text = "location  is disabled in phone settings.";
    }
    //else
    {
        // something else happened acquring the location
    }
}

这比 Windows 8 多一点工作：

        var overlay = new MapOverlay { PositionOrigin = new Point(0.5, 0.5), GeoCoordinate = coordinate };

        var img = new Image { Width = 56, Height = 56 };
        img.Source = new BitmapImage { UriSource = new Uri("/Assets/Icons/pin.png", UriKind.Relative) };
        img.Tag = coordinate;
        img.Tap += delegate
        {
            // handle tap
        };

        overlay.Content = img;

        var mapLayer = new MapLayer { overlay };
        map.Layers.Add(mapLayer);
