Windows phone 7 诺基亚地图Windows Phone中的边框

如何获取access地图边框

在WP7 Bing地图中，我可以使用属性BoundingRectangle，但在新的诺基亚地图中，我看不到类似的属性

感谢您的帮助。

我的方法是简单地为Map控件添加一个扩展方法，使用控件上的ConvertViewPortPointToGeoCoordination方法返回边界矩形：

public static class MapExtensions
{
    /// <summary>
    /// Returns the bounding rectangle representing the area displayed by the map contorl.
    /// </summary>
    /// <param name="map">The map control whose bounding rectangle should be returned.</param>
    /// <returns>The bounding rectangle representing the area displayed by the map contorl.</returns>
    public static MapBoundingRectangle GetBoundingRectangle( this Microsoft.Phone.Maps.Controls.Map map )
    {
        var lowerLeft   = map.ConvertViewportPointToGeoCoordinate( new System.Windows.Point( 0, map.ActualHeight ) );
        var upperRight  = map.ConvertViewportPointToGeoCoordinate( new System.Windows.Point( map.ActualWidth, 0 ) );

        return new MapBoundingRectangle( lowerLeft, upperRight );
    }
}

可能不是最棒的解决方案，但它解决了我的需要，所以我希望它能有所帮助。

试试看

 GeoCoordinate topLeft = Map.ConvertViewportPointToGeoCoordinate(new Point(0, 0));
            GeoCoordinate bottomRight = Map.ConvertViewportPointToGeoCoordinate(new Point(e.NewSize.Width, e.NewSize.Height));
            var bounds = LocationRectangle.CreateBoundingRectangle(topLeft, bottomRight);

请参阅LocationRectangle文档

 GeoCoordinate topLeft = Map.ConvertViewportPointToGeoCoordinate(new Point(0, 0));
            GeoCoordinate bottomRight = Map.ConvertViewportPointToGeoCoordinate(new Point(e.NewSize.Width, e.NewSize.Height));
            var bounds = LocationRectangle.CreateBoundingRectangle(topLeft, bottomRight);
