IO.Stream to Image in WPF

Question

I am trying to read an image from a resource only DLL file. I am able to read the image name and image bytes, but How do I set the Image control to stream buffer? In windows form, I know I can use this :

pictureBox1.Image=new System.Drawing.Bitmap(IOStream);

since there is no Drawing namespace in wpf, how can I achieve the same thing?

In WPF, you can set the Source property of an Image, as in this example:

Image image = new Image();
using (MemoryStream stream = new MemoryStream(byteArray))
{
    image.Source = BitmapFrame.Create(stream,
                                      BitmapCreateOptions.None,
                                      BitmapCacheOption.OnLoad);
}

Where byteArray is the array of bytes with the source of the image.

In WPF you probably have an Image element in your xaml. The Source can be any BitmapImage. You can bind a BitmapImage from your ViewModel, where you can create an instance from a Stream like this.
