windows phone 8.1 bing maps clustering

Question

您好我正在使用this链接中描述的Windows地图控件，我有一个MapLayer，其中多个MapOverlay在地图上有不同的pois。我想做集群的事情。我尝试this，但没有ClusteringLayer，也没有Pushpin。我该如何进行聚类？

var cluster = new ClusteringLayer();

layer = new ClusteringLayer(Mymap)
        {
            ClusterRadius = 10,
            ClusterType = ClusteringType.Grid
        };

//Add event handlers to create the pushpins 
layer.CreateClusteredItemPushpin += CreateClusteredItemPushpin1;
layer.CreateItemPushpin+=layer_CreateItemPushpin;

    private MapOverlay layer_CreateItemPushpin(object item, ClusteredPoint clusterInfo)
    {
        var x = clusterInfo.Location;
        var poi = new BuildingPoi { Coordinate = x, Buid = _selectedBuild };
        var imagePoiLocation = new Image
        {
            Source = new BitmapImage(new Uri("/Assets/MapPin.png", UriKind.Relative)),
            DataContext = poi
        };

        var over = new MapOverlay();

        imagePoiLocation.Tap += loadClickedBuilding;
        over.Content = imagePoiLocation;
        over.PositionOrigin = new Point(0.5, 0.5);
        over.GeoCoordinate = new GeoCoordinate(x.Latitude, x.Longitude);

        return over;
    }

    private MapOverlay CreateClusteredItemPushpin1(ClusteredPoint clusterInfo)
    {
        var x = clusterInfo.Location;
        var poi = new BuildingPoi { Coordinate = x, Buid = _selectedBuild };
        var imagePoiLocation = new Image
        {
            Source = new BitmapImage(new Uri("/Assets/MapPin.png", UriKind.Relative)),
            DataContext = poi
        };

        var over = new MapOverlay();

        imagePoiLocation.Tap += loadClickedBuilding;
        over.Content = imagePoiLocation;
        over.PositionOrigin = new Point(0.5, 0.5);
        over.GeoCoordinate = new GeoCoordinate(x.Latitude, x.Longitude);

        return over;
    }

由于他们没有任何nuget包或dll直接引用，您需要下载ClusteringLayer等特定类source code。 PushPin将相关.cs文件或项目本身添加到您的计算机，并在您的Windows Phone项目中添加此项目的引用，以获取ClusteringLayer和PushPin类。

请参阅ClusteringLayer课程的以下屏幕截图。对于其他类，只需将解决方案导入visual studio，您将看到所有类的源代码。 BTW，ClusteringLayer构造函数需要在集群中至少有一个参数。

我建议您下载源代码，并从源代码中的示例中熟悉它的用法。
