How to make BitmapImage disposable

Question

I need to use a BitmapImage in a using statement, how could this be done?

using (BitmapImage bitmap = new BitmapImage())
{
    ...

I am guessing the way to do it is by extending IDisposable but I have never done that before.

Thanks in advance

You can't do it. BitmapImage is sealed so you can't derive from it. Furthermore, I don't know why you would implement IDisposable in a .NET Framework class. The most you could do is a wrapper class which would contain your BitmapImage, and implement IDisposable.

Example:

class DisposableBitmapImageWrapper : IDisposable
{
    public BitmapImage Bitmap { get; private set; }

    public DisposableBitmapImageWrapper(BitmapImage bitmap)
    {
        Bitmap = bitmap;
    }

    public void Dispose()
    {
        //Do something with the BitmapImage
    }
}
