Set background of a stackpanel to an image in c#

Question

I need to set the Background of a Stackpanel to some image in the resources.
I know that i should set the background as follows:

Stack.Background= image; // don't know of what type the image should be how to set it   

Any help is appreciated,

Answer 1

string fileName = "/Background.png";
BitmapImage image = new BitmapImage(new Uri(fileName, UriKind.Relative));
ImageBrush brush = new ImageBrush();
brush.ImageSource = image;
stack.Background = brush;

Answer 2

StackPanel.Background is of type Brush, and you'll need to create an ImageBrush in order to display an image on the StackPanel.
