Memory Leak changing images in Windows Phone 7

Question

I have a problem when I change multiple times the image of an Image Container in the Windows Phone 7.5

Here\'s the faulty code:

public void displayIm         


        

Answer 1

The default behaviour of the Image control is to cache the image for future reuse. This means that the memory is still used by the contorl. You need to explicitly release the references to the image to free the memory

Like this:

  BitmapImage bitmapImage = image.Source as BitmapImage;
  bitmapImage.UriSource = null;
  image.Source = null;
