内存泄漏 Windows Phone

Question

我正在解析 KML 文件以显示路线，但内存不足且应用程序终止，谁能帮我解决这个问题

public void DisplayRoute(int i)
        {
            content = new KmlContent();
            info = Application.GetResourceStream(new Uri("/AppStudio;Component/Resources/kml", UriKind.Relative));
            data = content.DeserializeKml(info.Stream);
           if (data.Document.Placemarks[i].LineString != null)
                {
                        routeQuery = new RouteQuery();
                        routeQuery.Waypoints = content.ParseLocation(data.Document.Placemarks[i].LineString.Coordinates);
                        routeQuery.QueryAsync(); 
                        routeQuery.QueryCompleted += routeQuery_QueryCompleted;
                }
           else
           {
               return;
           }
        }

        int count = 0;
        public void routeQuery_QueryCompleted(object sender, QueryCompletedEventArgs<Route> e)
        {
            if (e.Error == null)
            {
                Route MyRoute = e.Result;
                MapRoute mappedRoute = new MapRoute(MyRoute);
                MainMap.AddRoute(mappedRoute);
                MainMap.SetView(mappedRoute.Route.BoundingBox);
                routeQuery.Dispose();
                count++;
            }
            DisplayRoute(count);
        }

第一次运行时会显示路线，当我导航到起始页面然后返回地图时，内存不足

问题是您永远不会释放从Application.GetResourceStream 获得的流。将您的代码更改为

using (info = Application.GetResourceStream(new Uri("/AppStudio;Component/Resources/kml", UriKind.Relative)))
{
    //rest of the code using info variable
}
