Loading Icons from a given path to display in WPF window

I have a tree that displays the directory and another panel that displays the files. Right now the files displayed have no icons. All i know is the path to the file. What i woudl like to do is get that files icon to display in that panel. I need the output to be and Image.source. Currently this is what i have

    private ImageSource GetIcon(string filename)
    {
        System.Drawing.Icon extractedIcon = System.Drawing.Icon.ExtractAssociatedIcon(filename);
        ImageSource imgs;

        using (System.Drawing.Icon i = System.Drawing.Icon.FromHandle(extractedIcon.ToBitmap().GetHicon()))
            {
                imgs = Imaging.CreateBitmapSourceFromHIcon(
                                        i.Handle,
                                        new Int32Rect(0, 0, 16, 16),
                                        BitmapSizeOptions.FromEmptyOptions());
            }

        return imgs;

From there i call my itme and try to change its default icon with:

ImageSource i = GetIcon(f.fullname)
ic.image = i

ic is the given item to the list, f.fullname contains the path here is the get and set of image

        public BitmapImage Image
        {
            get { return (BitmapImage)img.Source; }
            set { img.Source = value; }
        }

It doesn't work and this is one of many ways I've tried it says it cant cast the different types. Does anyone have a way to do this?
I'm completely lost.

I'm assuming that img is a standard Image control.

Your Image property is of type BitmapImage , which is a specific kind of ImageSource . CreateBitmapSourceFromHIcon returns an instance of an internal class called InteropBitmap , which cannot be converted to BitmapImage , resulting in an error.

You need to change you property to ImageSource (or BitmapSource , which CreateBitmapSourceFromHIcon returns, and inherits ImageSource ), like this:

public ImageSource Image
{
    get { return img.Source; }
    set { img.Source = value; }
}
