Question

I am trying to convert a varbinary to an image in my silverlight project.

First I get the Binary from my database in my service.

    [OperationContract]
    public byte[] getAfbeelding(int id)
    {

        var query = (from p in dc.Afbeeldings
                     where p.id == id
                     select p.source).Single();

        byte[] source = query.ToArray();

Then I try to convert the varbinary to an image, using code found on StackOverflow:

    public static string convertToImage(byte[] source)
    {
        MemoryStream ms = new MemoryStream(source);
        Image img = Image.FromStream(ms);
        return img.Source.ToString();
    }

But as it turns out, the silverlight Image does not have a .FromStream, I tried all the examples found in this thread but NONE of them work in silverlight.

'System.Windows.Controls.Image' does not contain a definition for 'FromStream'

So yeah, I’m kinda lost and am not sure what to do.
Any ideas on how to do this in silverlight?

You’re almost right. The following code should be all you need:

var bitmapImage = new BitmapImage();
bitmapImage.SetSource(new MemoryStream(imageData));
newImage.Source = bitmapImage;

where imageData is of type byte[] and newImage is the image you want to update.
