Cannot Access Closed Stream

Question

I\'m trying to use the Caching Application Block to cache some images (these images take a long time to render)

  BitmapSource bitmapSource; ///some bitmap s         


        

Answer 1

The problem is that the stream is closed (via Dispose()) at the end of the using block. You retain a reference to the closed stream.

Instead, save the contents of the stream to your cache:

_cache.Add(someId, stream.ToArray());

When you call the PngBitmapDecoder constructor, you'll have to create a new MemoryStream to read from that byte array.
