Silverlight 4.0: How to convert byte[] to image?

Question

public Image Base64ToImage(string base64String)
    {
        // Convert Base64 String to byte[]
        byte[] imageBytes = Convert.FromBase64String(base64String);
        MemoryStream ms = new MemoryStream(imageBytes, 0,
          imageBytes.Length);

        // Convert byte[] to Image
        ms.Write(imageBytes, 0, imageBytes.Length);
        System.Drawing.Image image = System.Drawing.Image.FromStream(ms, true);
        return image;
    }

I want to convert byte[] to image, however System.Drawing.Image is not supported in Silverlight. Any alternative?

You need to create an ImageSource and assign that to an Image control or use an ImageBrush to set on the background. BitmapImage is located in the System.Windows.Media.Imaging namespace.

        byte[] imageBytes = Convert.FromBase64String(base64String);
        using (MemoryStream ms = new MemoryStream(imageBytes, 0,
          imageBytes.Length))
        {
            BitmapImage im = new BitmapImage();
            im.SetSource(ms);
            this.imageControl.Source = im;
        }

or for the ImageBrush

        byte[] imageBytes = Convert.FromBase64String(base64String);
        using (MemoryStream ms = new MemoryStream(imageBytes, 0,
          imageBytes.Length))
        {
            BitmapImage im = new BitmapImage();
            im.SetSource(ms);
            imageBrush.ImageSource = im;
            this.BoxBorder.Background = imageBrush;
        }
