clear cache in window phone 7

Question

I want Dipose cache in window phone 7. In my project I have download Images, after use I Dispose Image by:

Image.sou         


        

Answer 1

To remove a downloaded image from the cache you need to assign it's source to a separate BitmapImage and set that to null before setting the image's source to null.

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

Don't ask me why, but it works.
