內存泄漏的Windows Phone

Question

我解析KML文件顯示的路線，但我跑出的內存和應用程序可以終止有人幫助我解決這個問題

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); 
     } 

用於顯示路由的第一次運行，當我導航到開始頁面，然後回到地圖我用盡內存

問題是，你永遠不會釋放你從Application.GetResourceStream得到的流。更改您的代碼爲

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